14 CFR Part 25

[Docket No. NM299; Special Conditions No. 25-283-SC]


Special Conditions: Boeing Model 767-300 Airplane; Forward Lower 
Deck Service/Cargo Compartment

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions; request for comments.

-----------------------------------------------------------------------

SUMMARY: These special conditions are issued for a Boeing Model 767-300 
airplane modified by Jet Aviation Engineering Services (JAES), Spring 
Branch, Texas. This modified airplane will have a novel or unusual 
design feature when compared to the state of technology envisioned in 
the airworthiness standards for transport category airplanes. The 
modification is associated with a forward lower deck compartment that 
will serve as both a service compartment and a Class C cargo 
compartment. The applicable airworthiness regulations do not contain 
adequate or appropriate safety standards for this design feature. These 
special conditions contain the additional safety standards that the 
Administrator considers necessary to establish a level of safety 
equivalent to that established by the existing airworthiness standards.

DATES: The effective date of these special conditions is February 14, 
2005.
    Comments must be received on or before February 28, 2005.

ADDRESSES: Comments on these special conditions may be mailed in 
duplicate to: Federal Aviation Administration, Transport Airplane 
Directorate, Attention: Rules Docket (ANM-113), Docket No. NM299, 1601 
Lind Avenue SW., Renton, Washington 98055-4056; or delivered in 
duplicate to the Transport Airplane Directorate at the above address. 
All comments must be marked: Docket No. NM299.

FOR FURTHER INFORMATION CONTACT: Gerald Lakin, FAA, Standardization, 
ANM-113, Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, 
Washington, 98055-4056; telephone (425) 227-1187; facsimile (425) 227-
1149.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice and 
opportunity for prior public comment hereon are impracticable, because 
those procedures would significantly delay issuance of the approval 
design and thus delivery of the affected aircraft. The FAA, therefore, 
finds that good cause exists for making these special conditions 
effective upon issuance.

Comments Invited

    Interested persons are invited to submit such written data, views, 
or arguments as they may desire. Comments should identify the rules 
docket number and be submitted in duplicate to the address specified 
above. The Administrator will consider all comments received on or 
before the closing date for comments. The special conditions may be 
changed in light of the comments received. All comments received will 
be available in the Rules Docket for examination by interested persons, 
both before and after the closing date for comments. A report 
summarizing each substantive public contact with FAA personnel 
concerning this rulemaking will be filed in the docket. Persons wishing 
the FAA to acknowledge receipt of their comments submitted in response 
to these special conditions must include with those comments a self-
addressed postcard on which the following statement is made: ``Comments 
to Docket No. NM299. The postcard will be date stamped and returned to 
the commenter.

Background

    On December 4, 2003, Jet Aviation Engineering Services (JAES) 
applied for a supplemental type certificate that would allow 
modification of a Boeing Model 767-300 airplane interior to an 
executive jet interior configuration. Boeing Model 767-300 series 
airplanes, currently approved under Type Certificate A1NM, are large 
transport category airplanes with a main passenger deck limited to 290 
passengers or fewer, depending on the interior configuration. As part 
of the type design, certified Class C cargo compartments are installed 
below the main deck.
    Jet Aviation Engineering Services proposes to include as part of 
the interior STC modification, access to the forward lower deck Class C 
cargo compartment and to convert that compartment for use as a combined 
service compartment and Class C cargo compartment (service/cargo 
compartment). Access will be provided by two hatches installed in the 
cabin floor, a primary hatch in the galley and a secondary hatch 
located in the crew rest area. A ladder will be installed at each hatch 
to provide access from the hatch to the forward lower deck service 
compartment floor.
    Access would be limited to one trained crewmember and would be 
allowed during level flight, but would not be allowed during taxi, 
takeoff and landing or during a fire.
    As part of the safety enhancement necessary to allow occupancy of 
the forward lower deck service/cargo compartment by a crewmember, JAES 
proposes the installation of warning and emergency equipment, as 
defined for a lower lobe service compartment in 14 CFR 25.819. 
Speakers, warning lights, and buzzers will be installed in the forward 
lower deck service/cargo compartment to warn an occupant of turbulent 
conditions, the presence of smoke or fire, or the need to leave the 
area. A crew interphone will be provided for communications with the 
flightdeck.
    Jet Aviation Engineering Services indicates that the forward lower 
deck service/cargo compartment will meet the Class C cargo requirements 
of Sec. Sec.  25.855 and 25.857. The compartment will be built using 
materials meeting the flammability standards for Class C cargo 
compartments and will have a smoke detection system. The compartment 
will be equipped with an approved built-in fire suppression system, 
which is controllable from the cockpit to eliminate the need to send 
someone into the compartment to fight a fire. In the event of a fire, 
the forward lower deck service/cargo compartment will be evacuated, and 
the pilot will activate the built-in fire suppression system. A means 
will be provided to prevent inadvertent access to the compartment when 
the fire suppression system has been activated.
    Current regulations specify the requirements for a forward lower 
deck service compartment (Sec.  25.819) and a Class C cargo compartment 
(Sec. Sec.  25.855 and 25.857) but the regulations did not envision a 
dual-purpose compartment. Currently, Sec.  25.819 specifies that a 
service compartment may be occupied and does not need to be evacuated 
under certain normal conditions or under certain unsafe conditions 
(e.g., in the case of fire, the occupant could function as a 
firefighter). The fire control system of a service compartment, 
however, would not utilize a flood-type fire suppressant, since the 
compartment might be occupied. Section 25.857, however, specifies that 
a Class C cargo compartment have a fire detection system and a built-in 
fire suppression system, i.e., a total flood system. The applicant 
intends to use the compartment as a dual-purpose service/cargo 
compartment and intends for the operator to use the built-in systems to 
fight fires in every instance.
    The concept of a multi-use compartment, which JAES proposes, would 
be acceptable if the FAA could be assured that whether the compartment 
is used as a service compartment or as a Class C cargo compartment, the 
level of safety would be equivalent to that of a separate service 
compartment or a separate Class C cargo compartment. Therefore, special 
conditions that provide an equivalent level of safety are being 
required. These special conditions pertain to visible and audible 
warnings, placards and limitations, equipment, evacuation routes, 
training, and the use of ladders between the main deck and the forward 
lower deck service/cargo compartment.

Type Certification Basis

    Under the provisions of 14 CFR 21.101, Jet Aviation Engineering 
Services must show that the Boeing Model 767-300 airplane, as modified, 
continues to meet the applicable provisions of the regulations 
incorporated by reference in Type Certificate A1NM or the applicable 
regulations in effect on the date of application for the change.
    The regulations incorporated by reference in the type certificate 
are commonly referred to as the ``original type certification basis.'' 
The regulations incorporated by reference in Type Certificate A1NM for 
the Boeing Model 767-300 series airplanes include 14 CFR part 25, as 
amended by Amendments 25-1 through 25-37 with certain additions and 
special conditions as listed in the type certificate data sheet. The 
U.S. type certification basis for the Boeing Model 767-300 series 
airplane is established in accordance with Sec. Sec.  21.17 and 21.21 
and the type certification application date.
    The type certification basis listed in Type Certificate Data Sheet 
No. A1NM, for the Boeing Model 767-300 does not include Sec.  25.819, 
which was introduced in Amendment 25-53. In this case, Sec.  25.819 
does provide appropriate safety standards for that portion of this 
STC's design considered a service compartment. Therefore, in lieu of 
applying the requirements of Sec.  25.819 as a special condition, Sec.  
25.819 (Amendment 25-110) will be added as a requirement to this STC's 
certification basis.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for a Boeing Model 767-300 series airplane 
because of a novel or unusual design feature, special conditions are 
prescribed under the provisions of Sec.  21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the Boeing Model 767-300 must comply with the fuel vent and 
exhaust emission requirements of 14 CFR part 34 and the noise 
certification requirements of 14 CFR part 36.
    Special conditions, as defined in 14 CFR 11.19, are issued in 
accordance with Sec.  11.38 and become part of the type certification 
basis in accordance with Sec.  21.101.
    Special conditions are initially applicable to the model for which 
they are issued. Should the applicant apply for a supplemental type 
certificate to modify any other model included on the same type 
certificate to incorporate the same novel or unusual design feature, 
the special conditions would also apply to the other model under the 
provisions of Sec.  21.101.

Novel or Unusual Design Features

    The Boeing Model 767-300 airplane will incorporate a novel or 
unusual design feature; specifically, the forward lower deck 
compartment will be used as a combined service compartment and Class C 
cargo compartment.

Discussion

    To allow the use of a dual-purposed service/cargo compartment, 
these

[[Page 2327]]

special conditions require certain visible and audible warnings, 
placards and limitations, equipment, and training. The applicant has 
not proposed a means of satisfying regulatory requirements governing 
occupancy of the forward lower deck service/cargo compartment during 
taxi, takeoff, and landing. Therefore, the FAA will specify appropriate 
limitations for such occupancy. A discussion of each specific special 
condition follows but is limited where the specific special condition 
is self-explanatory:

Special Condition 1--Visible and Audible Warnings

    To maintain the advantages of both a service compartment and a 
Class C cargo compartment, certain warnings need to be provided.
    Special Condition 1a requires a visible advisory in the cockpit to 
notify the flightcrew when the forward lower deck service/cargo 
compartment is occupied. The potential exists that the forward lower 
deck service/cargo compartment may inadvertently be occupied when it 
should not be, such as during taxi, takeoff or landing or during 
certain emergencies. Special Condition 1a also ensures that the 
flightcrew is aware that the forward lower deck service/cargo 
compartment is occupied in order that the flightcrew can take 
appropriate action to evacuate the compartment before flooding it with 
fire suppressant. There must be a placard or sign adjacent to the 
warning light which indicates that the light means that the compartment 
is occupied.
    Special Condition 1b requires an ``on/off'' visible warning placard 
stating ``Do Not Enter'' (or similar words) placard to be located on or 
near each hatch. The location should be on the main deck side of the 
hatch. The warning is to be controlled from the flightdeck to prevent 
someone from entering the forward lower deck service/cargo compartment 
when it should not be occupied; such as during taxi, takeoff or 
landing, or when smoke or fire has been detected. Opening the door 
during a fire would degrade the effectiveness of the fire suppressant 
and allow smoke, flame, and/or fire suppressant into the cabin.
    Special Condition 1c requires a visible and audible warning in the 
forward lower deck service/cargo compartment to notify an occupant that 
he or she must leave the compartment. This warning must be one which 
can be seen and heard from any part of the compartment. The visible and 
audible warning is to be controlled from the flightdeck. Because the 
forward lower deck service/cargo compartment may be occupied on the 
ground or in the air, a warning must be provided to notify an occupant 
to leave the compartment prior to taxi, takeoff or landing or during 
certain emergencies (other than fire, which is dealt with under Special 
Condition 1e). A visible warning is required, in case the audible 
warning becomes masked or distorted by engine, equipment, or ground 
noises.
    Special condition 1d requires a visible and audible warning in the 
forward lower deck service/cargo compartment to notify an occupant of 
the need to use a portable oxygen bottle in the event of decompression. 
This warning must be one which can be seen and heard from any part of 
the compartment and must be distinct from other warnings in the 
compartment to prevent confusion and to elicit correct action. The 
decompression warning must be automatic (i.e., not require separate 
crew action) to ensure that an occupant of the forward lower deck 
service/cargo compartment does not delay putting on the mask attached 
to the portable oxygen bottle. This section of the special conditions 
is partially in lieu of the visible effect provided by the automatic 
presentation feature required by Sec.  25.1447.
    Special Condition 1e requires a visible and audible warning in the 
forward lower deck service/cargo compartment when a fire is detected to 
notify an occupant that he or she must evacuate the compartment. The 
warning must be one which can be seen and heard from any part of the 
compartment and must be distinct from other warnings in the compartment 
in order to prevent confusion and to elicit the correct actions. The 
fire or smoke detection warning must be automatic (i.e., not require or 
depend on separate crew action) to ensure that an occupant of the 
forward lower deck service/cargo compartment leaves before the 
flightdeck crew releases fire suppressant in the compartment.

Special Condition 2--Placards and Limitations

    The forward lower deck service/cargo compartment must be evacuated 
if a fire occurs. In addition, there must be a way to prevent access 
into the compartment during taxi, takeoff or landing or in the event of 
a fire. Placards and limitations are specified for these situations.
    Special Condition 2a requires a placard to be located outside each 
hatch to the forward lower deck service/cargo compartment, indicating 
that access is limited to one crewmember trained in evacuation 
procedures.
    Special Condition 2b requires placards to be located inside and 
outside each hatch of the forward lower deck service/cargo compartment, 
indicating that the compartment hatch must remain closed, except when 
someone is entering or leaving the compartment. The hatches should 
remain closed except for entering or leaving the compartment so as to 
not degrade the fire detection and suppression systems, which are 
tested and certified with the compartment hatches closed. Further, with 
this limitation there is less chance someone will accidentally step 
through an open hatch.
    Special Condition 2c requires a limitation to be placed in the 
airplane flight manual (AFM) and placards to be posted inside and 
outside the hatches of the forward lower deck service/cargo 
compartment, all stating that (1) the compartment may not be occupied 
during taxi, takeoff, or landing or during a fire and (2) only 
authorized personnel are permitted access. These placards are being 
required, because the compartment is not being certified for occupancy 
during taxi, takeoff, or landing and because the compartment must not 
be occupied during a fire so that an occupant is not exposed to fire or 
to fire suppressant. These placards are somewhat redundant, given the 
warning required under Special Conditions 1b and 1c but would provide 
information to an occupant, if the flightcrew failed to activate the 
warnings of Special Conditions 1b and 1c.
    Special Condition 2d requires in the AFM (or AFM supplement) 
instructions for the flightcrew to follow regarding--
    (1) Permissible access and occupancy;
    (2) The need to exit (or evacuate in the event of an incapacitated 
person) and discharge (flood) extinguishing agent in the compartment; 
and
    (3) The need, after decompression warning, to immediately don the 
oxygen mask and exit the compartment.
    These requirements are to ensure that a single member of the crew 
could access the cargo compartment safely during flight and exit safely 
during failure conditions.
    Special Condition 2e. Because access is being provided to the 
forward lower deck service/cargo compartment, there is concern that 
during flight, passengers may retrieve hazardous materials or weapons 
stored in luggage. Access could be prevented by locking the forward 
lower deck service/cargo compartment, and that is being specified as 
one solution (in Special Condition 2e(1)). However, this airplane is 
being designed for use by a head-of-state, it will have limited access, 
and it will have placards limiting access.

[[Page 2328]]

Furthermore, there will be notification to the flightcrew when the 
forward lower deck service/cargo compartment is occupied (in Special 
Condition 1a). Special Condition 2e(2), therefore, would prohibit the 
airplane from being operated for hire or offered for common carriage.

Special Condition 3--Equipment

    In addition to that required by Sec.  25.819, Special Condition 3 
requires the following equipment:
    Special Condition 3a requires that two portable oxygen bottles be 
readily available at all times and that each be sufficient to supply a 
member of the crew who is occupying the forward lower deck service/
cargo compartment (except during taxi, takeoff, or landing, or during a 
fire). The supply of oxygen must be compatible with the emergency 
descent profile following a decompression. Because it would not be 
advisable to provide drop-down masks in a cargo compartment or to store 
a portable oxygen bottle in the compartment, the FAA is requiring that 
a portable oxygen bottles be mounted outside and near the main deck 
entrance of the forward lower deck service/cargo compartment. A member 
of the crew must carry the portable oxygen bottle, when he or she 
enters the compartment. The second bottle is for a second crewmember's 
use who must evacuate an incapacitated crewmember.
    Special Condition 3b requires supplemental handheld lighting (with 
locator light) when an occupant enters the forward lower deck service/
cargo compartment and any of the following three conditions exist: (1) 
Power to the compartment is off, (2) the emergency escape path lighting 
is off or lost, or (3) visibility is poor. At least two flashlights are 
required. One flashlight would be located adjacent to each emergency 
exit in the forward lower deck service/cargo compartment at the foot of 
the stairs in the compartment. Note that this requirement is in 
addition to the automatic emergency lighting system required by Sec.  
25.819(a).

Special Condition 4--Evacuation Routes

    To allow the forward lower deck service/cargo compartment to be 
utilized as a service compartment, Special Condition 4 requires a 
limitation to keep the two evacuation routes required under Sec.  
25.819(a) clear for evacuation. The cargo in the compartment must be 
restrained to ensure that the crewmember's paths to the exits are 
clear. Further, all entrances and exits (hatches) from the forward 
lower deck service/cargo compartment must be capable of being opened 
and closed, without obstruction. This allows exiting under emergency 
conditions. Further, the hatches must be able to be closed to maintain 
the integrity of the compartment with respect to fire detection and 
with respect to smoke, fire and extinguishing agent containment 
requirements applicable to the Class C cargo compartment, including 
Sec. Sec.  25.855, 25.857, and 25.858. Also see Special Condition 2b.

Special Condition 5--Training

    Because the design features required by these special conditions 
can fulfill their safety objectives only if crewmembers are properly 
trained in their use, these special conditions require the applicant to 
develop the following training materials:
    Special Condition 5a requires training materials about use of the 
forward lower deck service/cargo compartment and actions associated 
with the warnings and placards required by these special conditions.
    Special Condition 5b requires training materials about entering and 
exiting the forward lower deck service/cargo compartment, including 
emergency exiting, (associated with Special Conditions 1b, 1c, 1d, 1e, 
2a, 2b, 2c, 2d, and 3a).
    Special Condition 5c requires training materials about checking the 
pressure of the portable oxygen bottle prior to entering the forward 
lower deck service/cargo compartment (associated with Special Condition 
3a).
    Special Condition 5d requires training materials about carrying a 
portable oxygen bottle when entering the forward lower deck service/
cargo compartment (associated with Special Condition 3a).
    Special Condition 5e requires training materials about maintaining 
an exit aisle and access to the evacuation routes from the lower lobe 
service/cargo compartment (associated with Special Condition 2f and 4).
    Special Condition 5f requires a limitation in the AFM (or AFM 
supplement) stating all personnel accessing the forward lower deck 
service/cargo compartment must be trained in the procedures specified 
above. Special Condition 5f also states there should be at least two 
crewmembers (not the pilot or co-pilot) trained in emergency evacuation 
procedures. The second person is to aid the evacuation of an 
incapacitated crewmember should that occur.

Special Condition 6--Ladders

    The ladders between the forward lower deck service/cargo 
compartment and the main deck must meet the following requirements:
    Special Condition 6a requires that each ladder consist of a single 
segment (to minimize potential errors of use).
    Special Condition 6b requires that the ladders have essentially 
rectangular treads (to reduce the potential to slip).
    Special Condition 6c requires that general illumination of at least 
0.05 foot-candle, when measured along the centerlines of each tread, be 
provided, when the ladders are to be used (to facilitate evacuation and 
reduce miss-steps).

Applicability

    As discussed above, these special conditions are applicable to the 
Boeing Model 767-300 airplane. Should JAES apply at a later date for a 
supplemental type certificate to modify any other model included on 
Type Certificate A1NM to incorporate the same novel or unusual design 
feature, the special conditions would apply to that model as well under 
the provisions of Sec.  21.101.

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplane. It is not a rule of general applicability, 
and it affects only the applicant which applied to the FAA for approval 
of these features on the airplane.
    Under standard practice, the effective date of final special 
conditions would be 30 days after the date of publication in the 
Federal Register. However, as the certification date for the Boeing 
Model 767-300, as modified by JAES, is imminent, the FAA finds, that 
good cause exists to make these special conditions effective upon 
issuance.

The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

The Special Conditions

0
Accordingly, pursuant to the authority delegated to me by the 
Administrator, the following special conditions are issued as part of 
the type certification basis for the Boeing Model 767-300 airplane, 
modified by Jet Aviation Engineering Services, to include a forward 
lower deck compartment configured for use as both a service compartment 
and a Class C cargo compartment.

1. Visible and Audible Warnings

    In addition to the audible warnings (fire/smoke detection and

[[Page 2329]]

decompression) required by Sec.  25.819(c), the following warnings are 
required:
    a. A visible advisory in the cockpit to notify the flightcrew when 
the forward lower deck service/cargo compartment is occupied. The 
advisory light must be accompanied by a placard or message indicating 
that the compartment is occupied.
    b. A (on/off) visible warning placard stating ``Do Not Enter'' (or 
similar words) to be located on or near each hatch. The location should 
be on the main deck side of the hatch. The warning is to be controlled 
from the flightdeck.
    c. A visible and audible warning in the forward lower deck service/
cargo compartment to notify an occupant when he or she must evacuate 
the compartment. The warning must be one which can be seen and heard 
from any part of the compartment. The warning is to be controlled from 
the flightdeck.
    d. A visible and audible warning in the forward lower deck service/
cargo compartment, which in the event of decompression, warns an 
occupant of the need to use a portable oxygen bottle. This warning must 
be one which can be seen and heard from any part of the compartment and 
must be distinct from other warnings in the compartment. The 
decompression warning must be automatic (i.e., not require separate 
crew action), to ensure that an occupant of the forward lower deck 
service/cargo compartment does not delay using a portable oxygen 
bottle. This section of the special conditions is partially in lieu of 
the visible effect provided by the automatic presentation feature 
required by Sec.  25.1447.
    e. A visible and audible warning in the forward lower deck service/
cargo compartment, which in the event of a fire, warns an occupant of 
the need to evacuate the compartment. This warning must be one which 
can be seen and heard from any part of the compartment and should be 
distinct from other warnings in the compartment. The fire or smoke 
detection warning must be automatic (i.e., not require a separate crew 
action) to ensure that an occupant of the forward lower deck service/
cargo compartment leaves before the flightdeck crew releases fire 
suppressant.

2. Placards and Limitations

    In addition to those required in part 25, the following placards 
and limitations are required:
    a. A placard located outside each hatch to the forward lower deck 
service/cargo compartment, indicating that access to the compartment is 
limited to one crewmember trained in evacuation procedures.
    b. A placard located inside and outside each hatch to the forward 
lower deck service/cargo compartment, indicating that the compartment 
hatches must remain closed, except when someone is entering or leaving 
the compartment.
    c. A limitation in the AFM and a placard located inside and outside 
each hatch to the forward lower deck service/cargo compartment, all 
stating that (1) the forward lower deck service/cargo compartment must 
not be occupied during taxi, takeoff, or landing or during a fire, and 
(2) only authorized personnel are permitted access.
    d. Instructions in the AFM (or AFM supplement) for the flightcrew 
to follow regarding--
    (1) Permissible access and occupancy of the forward lower deck 
service/cargo compartment;
    (2) The need to exit (or evacuate in the event of an incapacitated 
person) and discharge (flood) extinguishing agent in the compartment; 
and
    (3) The need, after decompression warning, to immediately don the 
oxygen mask and exit the compartment.
    e. A Limitation in the AFM supplement stating that:
    ``Carriage of hazardous material and/or weapons in the forward 
lower deck service/cargo compartment is prohibited unless the following 
conditions are met:
    (1) The forward lower deck service compartment is locked during 
flight, and the key remains with the flightcrew, or
    (2) The airplane is not operated for hire or offered for common 
carriage. This provision does not preclude the operator from receiving 
remuneration to the extent consistent with 14 CFR part 125, and 14 CFR 
part 91, and subpart F, as applicable.''

3. Equipment

    In addition to that required by Sec. Sec.  25.819, the following 
equipment is required:
    a. Two portable oxygen bottles with masks must be readily available 
outside and near the primary main deck entrance (hatch) of the forward 
lower deck service/cargo compartment. Either portable oxygen bottle 
must be sufficient to supply a member of the crew who is occupying the 
forward lower deck service/cargo compartment and a bottle with mask 
attached must be carried by the crewmember when in the compartment. The 
second bottle is for the crewmember's use who must evacuate an 
incapacitated crewmember.
    b. Flashlights or other supplemental handheld lighting, in addition 
to the emergency illumination required by Sec.  25.819(a). At least two 
flashlights, each equipped with a locator light, must be provided. A 
flashlight must be located adjacent to each emergency exit (hatch) at 
the foot of the ladder in the forward lower deck service/cargo 
compartment.

4. Evacuation Routes

    A limitation must be placed in the AFM (or AFM supplement) stating 
that:
    When the forward lower deck service/cargo compartment is operated 
as a service compartment, the two evacuation routes must be kept clear, 
the special storage pallets/containers must be installed, no loose 
storage is permitted, and all items stored in the compartment must be 
stored in appropriate pallets/containers (or similar words).
    Similar loading restrictions should be placed in the weight and 
balance manual.

5. Training

    Training manuals must be provided for authorized crewmembers that 
may enter the forward lower deck service/cargo compartment and the 
manuals and training shall include:
    a. Use of the forward lower deck service/service compartment and 
actions indicated by the warnings and placards specified herein.
    b. Entering and exiting the forward lower deck service/cargo 
compartment, including emergency exiting.
    c. Checking the pressure of the portable oxygen bottle prior to 
entering the forward lower deck service/cargo compartment.
    d. Carrying a portable oxygen bottle when entering the forward 
lower deck service/ cargo compartment.
    e. Maintaining an exit aisle and access to evacuation routes from 
the forward lower deck service/cargo compartment. Training must address 
how to keep the evacuation routes clear, i.e., how to restrain cargo in 
the compartment to ensure that the paths to the exits (hatches) are 
clear.
    f. A limitation in the AFM supplement stating that all personnel 
accessing the forward lower deck service/cargo compartment must be
