Airworthiness Directives; The Cessna Aircraft Company Models 208 
and 208B Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA adopts a new airworthiness directive (AD) for all The 
Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. This AD 
requires you to install the pilot assist handle (part number (P/N) 
SK208-146-2) (or FAA-approved equivalent part number) and deicing boots 
on the cargo pod and landing gear fairings (part number (P/N) AK208-6C) 
(or FAA-approved equivalent part number); and make changes to the 
Pilot's Operating Handbook (POH) and FAA-approved Airplane Flight 
Manual (AFM). This AD results from reports of several accidents 
involving the affected airplanes during operations in flight and in 
ground icing conditions. We are issuing this AD to provide a safe 
method to detect ice, snow, frost, or slush adhering to the upper wing 
(a critical surface) prior to takeoff; and to reduce drag in-flight by 
shedding ice on the cargo pod and landing gear fairings. Ice adhering 
to the upper wing surface, cargo pod, or landing gear fairings could 
result in a reduction in airplane performance with the consequences 
that the airplane cannot perform a safe takeoff or climb.

DATES: This AD becomes effective on February 22, 2006.
    As of February 22, 2006, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulation.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The FAA has received several 
reports of accidents and incidents concerning problems with Cessna 
Models 208 and 208B airplanes during operations in icing conditions. 
This includes a total of six accidents in the previous two icing 
seasons and nine other incidents. One-third of the Model 208 icing-
related accidents occurred as a result of loss of control after takeoff 
in ground icing conditions. One-third is suspected to have occurred in 
supercooled large droplets, icing conditions outside the 14 CFR part 25 
Appendix C certification envelope. The Cessna Models 208 and 208B are 
certificated to 14 CFR part 23, but 14 CFR part 23 references 14 CFR 
part 25 Appendix C for icing certification.
    Findings from the accidents conclude that there was a reduction in 
airplane performance due to drag from airframe ice accretion. The 
airplanes could not perform a safe takeoff, climb, or maintain 
altitude.
    What is the potential impact if FAA took no action? Ice adhering to 
critical surfaces could result in a reduction in airplane performance 
with the consequence that the airplane cannot climb or maintain 
altitude.
    Has FAA taken any action to this point? We issued a proposal to 
amend part 39 of the Federal Aviation Regulations (FAR) (14 CFR part 
39) to include an AD that would apply to all The Cessna Aircraft 
Company (Cessna) Models 208 and 208B airplanes. This proposal was 
published in the Federal Register as a notice of proposed rulemaking 
(NPRM) on June 21, 2005 (70 FR 35565). The NPRM proposed to require you 
to install a pilot assist handle, Cessna part number SK208-146-2, for 
all affected airplanes, install deicing boots on landing gear struts 
and cargo pod, Cessna part number AK208-6C, for all affected airplanes, 
and make changes to the Pilot's Operating Handbook (POH) and FAA-
approved Airplane Flight Manual (AFM), and to the POH and AFM 
Supplement S1 for all affected airplanes.

Comments

    Was the public invited to comment? We provided the public the 
opportunity to participate in developing this AD. The following 
presents the comments received on the proposal and FAA's response to 
each comment:

Comment Issue No. 1: Allow Installation of Replacements Parts Approved 
Under 14 CFR 21.303

    What is the commenter's concern? The commenter, the Modification 
and Replacement Parts Association (MARPA), states that the Parts 
Manufacturer Approval (PMA), 14 CFR 21.303, provides an alternative 
mechanism for the design, production, sale, and installation of 
aeronautical items other than those specified by the original equipment 
manufacturer (OEM). While no alternative PMA parts are currently known 
to exist, alternative PMA parts may be created in the future and the AD 
action should take into account that possibility.
    The MARPA requests that the AD language state that installation of 
replacements parts approved under 14 CFR 21.303 is permitted.
    What is FAA's response to the concern? We agree with the MARPA. The 
FAA will add the phrase ``or FAA-approved equivalent part number'', and 
add language to cover the PMA replacement parts.

Comment Issue No. 2: Withdraw the Requirement for the Pilot Assist 
Handle

    What is the commenter's concern? Three commenters, two owners/
operators and the Regional Air Cargo Carriers Association (RACCA), 
request the withdrawal of the requirement for the pilot assist handle.

[[Page 1942]]

    The commenters justify the request for withdrawal of the proposed 
requirement for the pilot assist handle reasoning that it is more cost 
effective and the results will be better to continue the course of 
crewmember training and education. Further, a handle will not allow the 
pilot to make better decisions. Lastly, the affected airplanes' ability 
to operate in and out of smaller airports, which typically do not have 
ground de-ice facilities or capabilities, require the flight crew to be 
especially diligent in pre-takeoff examination, assessment, and 
judgment.
    The RACCA also notes these reasons to withdraw the requirement for 
the pilot assist handle:

--The operator may employ alternative methods of gaining access to 
upper wing surface, and these methods may provide better access to a 
variety of locations along the wingspan.
--It may be extremely dangerous and result in personal injury (from a 
fall) to do the tactile inspection while attempting to stand on the 
doorsill and hang from the pilot assist handle after the application of 
deicing/anti-icing fluid may be extremely dangerous and result in 
personal injury from a fall.
--It may be challenging or impossible for some pilots to reach the 
intended tactile inspection area, and this could easily be challenged 
under the Americans with Disabilities Act.

    What is FAA's response to the concern? The FAA acknowledges the 
points made by the commenters to this issue. Rather than mandating 
installation of a pilot assist handle for all affected airplanes, FAA 
will mandate a revision to the Required Equipment List in the 
Limitations section of the basic AFM. This revision will require 
installation of the pilot assist handle in ground icing conditions 
currently defined in the AFM Limitations section. This AD does not 
mandate where on the wingspan a pre-takeoff tactile inspection is done 
and does not preclude an owner/operator from inspecting the upper wing 
with a ladder. It provides the type design one safe method to do the 
tactile check on the upper wing surface, particularly the pretakeoff 
contamination check required in part 135 operations during ground icing 
conditions.
    We have revised the final rule to reflect this change.

Comment Issue No. 3: Withdraw the Proposed Requirement To Install 
Deicing Boots on the Cargo Pod and Landing Gear

    What is the commenter's concern? Two commenters seek the withdrawal 
of the proposed requirement to install deicing boots on the cargo pod 
and landing gear. The first commenter wants FAA to also show the 
statistical probable cause and result of each known icing accident 
involving Cessna Models 208 and 208B airplanes. Further, the commenter 
wants FAA to prove that the proposed additional equipment would have 
prevented a substantial number of these accidents.
    The second commenter, an airline transport pilot, in a personal 
anecdote describes ice adhering to critical surfaces of the Cessna 
Model 208B airplane that he was piloting despite the airplane being 
equipped with deicing boots on the landing gear struts and cargo pod. 
The commenter describes loss of control at high airspeed under icing 
conditions.
    The second commenter expresses concern that the installation of 
deicing boots on the landing gear struts and cargo pod on Cessna Models 
208 and 208B airplanes will give pilots and operators of these 
airplanes a false sense of security that the problem of ice handling 
ability of the airplane has been resolved. This commenter indicates 
that poor performance of the existing deicing boots is a factor in loss 
of control accidents and that redesign of the existing systems is 
needed.
    We conclude that the second commenter wants FAA to withdraw the 
proposed requirement to install deicing boots on the cargo pod and 
landing gear.
    What is FAA's response to the concern? Loss of control after 
takeoff caused one-third of the fatal accidents involving the affected 
airplanes, and the other two-thirds occurred in-flight. Approximately 
50-percent of the airplanes involved in in-flight icing related 
accidents were not equipped with deicing boots on the landing gear and 
on the cargo pod if equipped with a cargo pod. Approximately 80-percent 
of the airplanes involved in in-flight accidents suspected to be in 
supercooled large drops were not equipped with these boots. Our drag 
analysis shows that the service ceiling in icing is decreased by more 
than 1,000 feet in critical icing conditions without this equipment. 
Cessna flight-testing of artificial ice shapes validated this analysis. 
Regarding the loss of control at high airspeed, FAA and the 
manufacturer evaluated longitudinal control with artificial ice shapes 
and have found no problems.
    As for performance of the deicing boots, FAA has conducted icing 
tunnel tests on a similar general aviation airfoil and deicing boots. 
The results will be reported in 2006. The results of these tests are 
reflected in revisions to the Airplane Flight Manual Known Icing 
Supplement Limitations and Procedures during 2005.
    We have revised the AD to modify the estimated costs of compliance.

Comment Issue No. 4: Require Cargo Pod and Landing Gear Deicing Boots 
on Only Those Airplanes Equipped With Pneumatic Deicing Boots and 
Approved for Flight in Icing Conditions

    What is the commenter's concern? Two commenters, one the U.S. 
Parachute Association (USPA), write that many operators operate their 
Models 208 and 208B airplanes in visual meteorological conditions (VMC) 
and have no intention on flying into known icing conditions or 
instrument meteorological conditions (IMC).
    Comments from the USPA note that some jump-configured Cessna Models 
208 and 208B airplanes are equipped with pneumatic deicing boots. The 
USPA letter also indicates that on some airplanes the boots have been 
deactivated. In other cases, the boots are operational, but the 
operator indicates that the aircraft does not have the added equipment 
that would permit flight into known icing conditions; is not flown in 
instrument meteorological conditions; or is not flown in known icing 
conditions. The requirement for deicing boots on the cargo pod and 
landing gear might result in some operators removing or deactivating 
the deicing boots to avoid the requirements of the AD.
    In light of the above, the USPA proposes that instead of installing 
the deicing boots, allow the owners/operators of jump airplanes to 
install a placard (within the pilot's clear view) that restricts the 
airplane from flight into known icing conditions.
    What is FAA's response to the concern? The FAA recognizes that some 
owners/operators of the affected aircraft do not operate in known icing 
conditions. Our intent in the proposed rule was not to mandate the 
cargo pod and landing gear deicing boots on airplanes unapproved for 
flight in icing or for airplanes owners to remove or deactivate the 
deicing boots.
    For the final rule, we added an option for airplanes discussed in 
the previous paragraph to require installing a placard that prohibits 
flight in icing conditions instead of installing the cargo pod and 
landing gear fairing deicing boots.

Comment Issue No. 5: Delay the Proposed Requirement To Install the 
Cargo Pod and Landing Gear Deicing Boots Until Cessna Flight Tests Are 
Completed

    What is the commenter's concern? Two commenters, Cessna and the

[[Page 1943]]

RACCA, forwarded correspondence to FAA that suggests delaying the 
proposed requirement to install the deicing boots on the cargo pod and 
landing gear.
    In a recent letter to RACCA, Cessna's Director of Airworthiness and 
Product Safety stated the following:
    ``Cessna does not believe that an unsafe condition exists in the 
design of aircraft equipped with pneumatic deice boots for flight into 
known icing and not equipped with cargo pod and main landing gear deice 
boots.'' He continued by indicating that Cessna is planning to conduct 
additional flight tests to determine if the rate of climb performance 
is significantly improved in icing conditions and that mandatory action 
(presumably the AD) ``should be delayed until completion of analysis of 
this testing.''
    We conclude that in light of the letter from Cessna, the RACCA 
wants FAA to delay requiring owners/operators of the affected aircraft 
to install the cargo pod and landing gear deicing boots until Cessna's 
flight tests are completed.
    What is FAA's response to the concern? The FAA reviewed the results 
of Cessna artificial ice shape testing and determined the results 
validate the FAA drag analysis. We have retained the requirement to 
install deicing boots on the cargo pod and landing gear.

Comment Issue No. 6: Withdraw the Proposed Rule, Conduct Public 
Hearings, and as a Result of the Public Hearings, Issue a New NPRM

    What is the commenter's concern? The Alaska Air Carriers 
Association (AACA) requested that FAA withdraw the proposed rule, 
conduct at least two public hearings on the proposed changes; and based 
upon the comments received under this docket and from the public 
hearings, issue another document on this proposed rule. The AACA 
reasoning for the comment issue included the following points.

--The proposed rule is extremely burdensome, especially in light of the 
requirements of the Regulatory Flexibility Analysis. The AACA estimated 
that the cost of outfitting each Cessna 208/208B with the required 
items and making the proposed changes to the POH/AFM is $13,041, not 
$9,653 as FAA estimated the cost impact.
--The proposed rule would expand requirements without any evidence that 
it would enhance safety.
--The proposed rule does not address necessary training for owners/
operators of the affected aircraft.

    What is FAA's response to the concern? The FAA does not agree with 
the reasoning of the AACA for this comment issue. The FAA has 
determined that the requirements regarding a Regulatory Flexibility 
Analysis have been met and that, since an unsafe condition exists, we 
should issue the AD. Further, the impact on continued operational 
safety outweighs the cost to comply. The FAA does not believe that 
there is a need for any public meetings.
    We are not making changes to the final rule based on this comment 
except we have modified the estimated cost of compliance. Also, owners 
and operators always have the option to apply for a FAA-approved 
alternative method to the pilot assist handle that will allow the 
inspection required in the AFM Limitations section. An example is a 
ladder that allows inspection of the upper wing extending out to two 
feet behind the deicing boot and is properly secured inside the 
airplane when not in use. Such an alternative would not be considered 
for part 135 operators that are approved to operate in ground icing 
conditions. The pilot assist handle is required to safely and quickly 
conduct a pretakeoff contamination check within five minutes of 
takeoff.

Comment Issue No. 7: Prohibit Flights Into Forecast and Known Icing 
Conditions, Make a Special Airworthiness Review of the Aircraft 
Certification for Operations in Icing Conditions, and Evaluate 
Alternative Airframe Ice Protection Technologies

    What is the commenter's concern? The commenter states that the row 
of vortex generators on top of the horizontal stabilizer just forward 
of the elevator, which enhance nose down elevator and trim authority, 
may lose effectiveness in icing conditions. Additionally, the commenter 
states that the pilot assist handle will not permit (without use of a 
ladder) adequate inspection of all the upper tailplane surfaces 
including the vortex generators. Therefore, the commenter recommends 
that FAA prohibit flights of Cessna Model 208 and 208B aircraft into 
forecast and known icing conditions until a Special Airworthiness 
Review of the Aircraft Certification for operations in icing conditions 
(with focus on the tailplane icing issue) is done, including review and 
evaluation of alternative airframe ice protection technologies.
    What is FAA's response to the concern? The FAA does not concur. The 
tailplane vortex generators were installed to improve trim authority 
not as a result of ice contaminated tailplane stall (ICTS). The 
critical tail surface is the underside of the tail, and the critical 
wing surface is the upper surface. We note that sandpaper ice, which 
has been shown to be just as critical as ice shapes for ICTS 
susceptibility, has been evaluated on the Cessna Model 208. As 
mentioned in our above responses to other commenters, Cessna is 
conducting flight tests that will include intercycle ice with horn 
shapes associated with glaze ice along the entire span of the 
horizontal stabilizer and on the elevator horns. The flight tests will 
also evaluate longitudinal control and trim at critical center of 
gravity. Before deciding on any further rulemaking action, FAA will 
review the test results and the potential for ice to accrete on the 
vortex generators and the resulting effect.
    The FAA is not making changes to the final rule based on this 
comment.

Conclusion

    What is FAA's final determination on this issue? We have carefully 
reviewed the available data and determined that air safety and the 
public interest require adopting the AD as proposed except for the 
changes discussed above and minor editorial corrections. We have 
determined that these changes and minor corrections:

--Are consistent with the intent that was proposed in the NPRM for 
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already 
proposed in the NPRM.

Changes to 14 CFR Part 39--Effect on the AD

    How does the revision to 14 CFR part 39 affect this AD? On July 10, 
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, 
July 22, 2002), which governs the FAA's AD system. This regulation now 
includes material that relates to altered products, special flight 
permits, and alternative methods of compliance. This material 
previously was included in each individual AD. Since this material is 
included in 14 CFR part 39, we will not include it in future AD 
actions.

Authority for This Rulemaking

    What authority does FAA have for issuing this rulemaking action? 
Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106 describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this AD.

Regulatory Findings

    Will this AD impact various entities? We have determined that this 
AD will not have federalism implications under Executive Order 13132. 
This AD will not have a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.
    Will this AD involve a significant rule or regulatory action? For 
the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2005-21275; Directorate Identifier 2005-CE-28-AD'' in your 
request.

2. FAA amends Sec.  39.13 by adding a new AD to read as follows:

2006-01-11 The Cessna Aircraft Company: Amendment 39-14450; Docket 
No. FAA-2005-21275; Directorate Identifier 2005-CE-28-AD.

When Does This AD Become Effective?

    (a) This AD becomes effective on February 22, 2006.

What Other ADs Are Affected by This Action?

    (b) None.

What Airplanes Are Affected by This AD?

    (c) This AD affects Models 208 and 208B, all serial numbers, 
that are certificated in any category.

What Is the Unsafe Condition Presented in This AD?

    (d) This AD is the result of reports of several accidents 
involving the affected airplanes during operations in-flight and in 
ground icing conditions. We are issuing this AD to provide a safe 
method to detect ice, snow, frost, or slush adhering to the upper 
wing (a critical surface) prior to takeoff; and to reduce drag in-
flight by shedding ice on the cargo pod and landing gear fairings. 
Ice adhering to the upper wing surface, cargo pod, or landing gear 
fairings could result in a reduction in airplane performance with 
the consequences that the airplane cannot perform a safe takeoff or 
climb or maintain altitude.

What Must I Do To Address This Problem?

    (e) To address this problem, you must do the following:
