14 CFR Part 39

[Docket No. FAA-2007-28370; Directorate Identifier 2003-NM-239-AD]
RIN 2120-AA64


Airworthiness Directives; Goodrich Evacuation Systems Approved 
Under Technical Standard Order (TSO), TSO-C69, TSO-C69a, TSO-C69b, and 
TSO-69c, Installed on Various Boeing, McDonnell Douglas, and Airbus 
Transport Category Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Goodrich evacuation systems approved under TSO-C69, TSO-
C69a, TSO-C69b, and TSO-69c, installed on certain Boeing, McDonnell 
Douglas, and Airbus transport category airplanes. For certain systems, 
this proposed AD would require replacing the evacuation systems shear-
pin restraints with new ones. For certain other systems, this proposed 
AD would require an inspection for manufacturing lot numbers; and a 
general visual inspection of the shear-pin restraint for discrepancies, 
and corrective actions if necessary. This proposed AD is prompted by 
several reports of corroded shear-pin restraints that prevented 
Goodrich evacuation systems from deploying properly. We are proposing 
this AD to prevent failure of the evacuation system, which could impede 
an emergency evacuation and increase the chance of injury to passengers 
and flightcrew during the evacuation.

DATES: We must receive comments on this proposed AD by July 23, 2007.

Discussion

    We have received several reports indicating that Goodrich 
evacuation systems installed on certain Boeing Model 747 airplanes and 
Model 767 airplanes have not deployed properly due to corroded shear-
pin restraints. The corrosion problem arose concurrently with a 1998 
change in the anodize specification for restraint bodies. Corrosion of 
the shear-pin restraints, if not corrected, can lead to higher than 
designed release values, and in severe cases, can cause the two halves 
of the restraints to freeze up, which can lead to improper deployment 
and/or loss of use of the evacuation system. That loss could impede 
emergency evacuation and increase the chance of injury to passengers 
and flightcrew during the evacuation.

Other Relevant Rulemaking

    The reports involved certain Boeing Model 747 airplanes and Model 
767 airplanes that are equipped with the affected Goodrich evacuation 
system as part of a type certificate (TC); however, certain Goodrich 
evacuation systems installed as a technical standard order (TSO) 
appliance on certain Airbus, Boeing and McDonnell Douglas transport 
category airplanes use the same restraints as those used by the 
affected type certificated Goodrich units. Therefore evacuation systems 
approved by either TSO or TC are subject to the identified unsafe 
condition. We are planning to issue similar rulemaking (Directorate 
Identifier 2005-NM-139-AD) for certain Boeing Model 747 airplanes and 
Model 767 airplanes that are equipped with certain type certificated 
Goodrich evacuation systems.

Relevant Service Information

    We have reviewed Goodrich Service Bulletins 25-343, Revision 3, 
dated January 12, 2007; and 25-344, Revision 2, dated October 11, 2006. 
Goodrich Service Bulletin 25-343 affects evacuation systems installed 
on certain Boeing and McDonnell Douglas transport category airplanes. 
Goodrich Service Bulletin 25-344 affects evacuation systems installed 
on certain Airbus transport category airplanes. For certain systems, 
the service bulletins describe procedures for replacing the shear-pin 
restraints with new, improved restraints. For certain other systems, 
the service bulletins describe procedures for an inspection to verify 
the manufacturing lot number of the restraints; and a general visual 
inspection of the restraints for discrepancies (i.e., corrosion, 
security of pin retainer/label, overall condition, and lack of play), 
and corrective action if necessary. The corrective action is replacing 
the shear-pin restraints with new shear-pin restraints. Accomplishing 
the actions specified in the service information is intended to 
adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other products 
of this same type design. Therefore, we are proposing this AD, which 
would require you to use the service information described previously 
to perform these actions, except as discussed under ``Difference 
Between this Proposed AD and the Service Bulletins.''

Difference Between This Proposed AD and the Service Bulletins

    Although the service bulletins recommend accomplishing the 
replacement or inspection ``at the next shop visit,'' we have 
determined that this imprecise compliance time would not address the 
identified unsafe condition soon enough to ensure an adequate level of 
safety for the affected fleet. In developing an appropriate compliance 
time for this AD, we considered the manufacturer's recommendation, the 
degree of urgency associated with the subject unsafe condition, and the 
average utilization of the affected fleet. In light of all of these 
factors, we find that a compliance time of 18 months for Goodrich 
evacuation systems installed on Boeing Model 767 off-wing ramp/slide 
units and 36 months for all other evacuation systems represents an 
appropriate interval of time for affected airplanes to continue to 
operate without compromising safety. We have coordinated this 
difference with the manufacturer.

Costs of Compliance

    This proposed AD would affect certain Goodrich evacuation systems 
installed on about 2,844 airplanes worldwide. This proposed AD would 
affect about 1,240 airplanes of U.S. registry. The following table 
provides the estimated costs for U.S. operators to comply with this 
proposed AD.

Authority for This Rulemaking

    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 
rulemaking action.

Regulatory Findings

    We have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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.
    For the reasons discussed above, I certify that the proposed 
regulation:
    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 regulatory evaluation of the estimated costs to 
comply with this proposed AD. See the ADDRESSES section for a location 
to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD is prompted by several reports of corroded shear-pin 
restraints that prevented Goodrich evacuation systems from deploying 
properly. We are issuing this AD to prevent failure of the 
evacuation system, which could impede an emergency evacuation and 
increase the chance of injury to passengers and flightcrew during 
the evacuation.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Service Bulletin Reference

    (f) The term ``service bulletin,'' as used in this AD, means the 
following service bulletins, as applicable:
    (1) For Goodrich evacuation systems identified in Table 3 of 
this AD: Goodrich Service Bulletin 25-344, Revision 2, dated October 
11, 2006; and
    (2) For Goodrich evacuation systems identified in Tables 1 and 2 
of this AD: Goodrich Service Bulletin 25-343, Revision 3, dated 
January 12, 2007.

Compliance Times

    (g) Perform the actions specified in paragraph (h) of this AD at 
the applicable compliance time specified in paragraph (g)(1) or 
(g)(2) of this AD.
    (1) For Goodrich evacuation systems installed on Boeing Model 
767 airplanes as off-wing ramp/slide units and identified in Table 1 
of this AD: Do the actions within 18 months after the effective date 
of this AD.
    (2) For Goodrich evacuation systems other than those identified 
in paragraph (g)(1) of this AD: Do the actions within 36 months 
after the effective date of this AD.

Replacement, or Inspections and Corrective Action

    (h) Do the actions specified in paragraph (h)(1) or (h)(2) of 
this AD in accordance with the Accomplishment Instructions of the 
applicable service bulletin.
    (1) For Goodrich evacuation systems identified in paragraphs 
(c)(1)(i) through (c)(1)(xxxi) inclusive in Table 1 of this AD, 
(c)(2)(i) through (c)(2)(iii) inclusive in Table 2 of this AD, and 
(c)(3)(i) through (c)(3)(xviii) inclusive in Table 3 of this AD: 
Replace the shear-pin restraints with new restraints.
    (2) For Goodrich evacuation systems identified in paragraphs 
(c)(1)(xxxii) through (c)(1)(lxii) inclusive in Table 1 of this AD, 
(c)(2)(iv) through (c)(2)(ix) inclusive in Table 2 of this AD, and 
(c)(3)(xix) through (c)(3)(xxx) inclusive in Table 3 of this AD: Do 
an inspection to verify the manufacturing lot number of the shear-
pin restraint. A review of airplane maintenance records is 
acceptable in lieu of this inspection if the manufacturing lot 
number of the shear-pin restraint can be conclusively determined 
from that review.
    (i) If a manufacturing lot number from 3375 through 5551 
inclusive is found, before further flight, replace the shear-pin 
restraint with a new restraint.
    (ii) If a manufacturing lot number from 3375 through 5551 
inclusive is not found, do a general visual inspection of the shear-
pin restraints for discrepancies (i.e., corrosion, security of pin 
retainer/label, overall condition, and lack of play). If any 
discrepancy is found, before further flight, replace the shear-pin 
restraint with a new restraint.
    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

Parts Installation

    (i) As of the effective date of this AD, no Goodrich evacuation 
system identified in paragraph (h)(1) of this AD may be installed on 
any airplane, unless the shear-pin restraints have been replaced 
with new restraints in accordance with paragraph (h)(1) of this AD.
    (j) As of the effective date of this AD, no Goodrich evacuation 
system identified in paragraph (h)(2) of this AD may be installed on 
any airplane, unless the shear-pin restraints have been inspected 
and found acceptable in accordance with paragraph (h)(2) of this AD.

Credit for Actions Done Using Previous Service Information

    (k) Replacements and inspections done before the effective date 
of this AD in accordance with the applicable service bulletins 
identified in Table 4 of this AD, are acceptable for compliance with 
the requirements of paragraph (h) of this AD.
