[Federal Register: October 9, 2008 (Volume 73, Number 197)] [Rules and Regulations] [Page 59486-59488] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr09oc08-3] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2008-0302; Directorate Identifier 2007-NM-323-AD; Amendment 39-15689; AD 2008-21-05] RIN 2120-AA64 Airworthiness Directives; Boeing Model 767-200, -300, and -400ER Series Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767-200, -300, and -400ER series airplanes. That AD currently requires an inspection to determine if the door-mounted escape slide/rafts have certain part numbers. This new AD does not retain that requirement. This new AD continues to require an inspection for excessive tension of the firing cable, and procedures for providing slack in the firing cable or rerouting the firing cable if necessary. For certain airplanes, this new AD also requires a review of the airplane maintenance records to determine if a certain service bulletin has been incorporated, or an inspection to determine if certain door-mounted escape slide/rafts are installed. This new AD also requires modification of certain escape slide/rafts. This AD results from reports of uncommanded inflation inside the airplane of a door-mounted escape slide/raft located in the passenger compartment. We are issuing this AD to prevent injury to maintenance personnel, passengers, and crew during otherwise normal operating conditions and to prevent interference with evacuation of the airplane during an emergency, due to uncommanded inflation of a door-mounted escape slide/raft. DATES: This AD becomes effective November 13, 2008. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 13, 2008. On June 30, 2005 (70 FR 34638, June 15, 2005), the Director of the Federal Register approved the incorporation by reference of a certain other publication. ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124- 2207.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2005-12-14, amendment 39-14130 (70 FR 34638, June 15, 2005). The existing AD applies to certain Boeing Model 767-200, -300, and -400ER series airplanes. That NPRM was published in the Federal Register on March 18, 2008 (73 FR 14405). That NPRM proposed to continue to require an inspection to determine if the door-mounted escape slide/rafts have certain part numbers. For those door-mounted escape slide/rafts having certain part numbers, the NPRM also proposed to continue to require an inspection for excessive tension of the firing cable, and procedures for providing slack in the firing cable or rerouting the firing cable if necessary. For certain airplanes, the NPRM also proposed to require a review of the airplane maintenance records to determine if a certain service bulletin has been incorporated, or an inspection to determine if certain door-mounted escape slide/rafts are installed. The NPRM also proposed to require modification of certain escape slide/rafts. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been received on the NPRM. Request To Refer to Certain Part Numbers (P/Ns) in the Applicability Boeing requests that we revise the applicability to Boeing Model 767-200, -300, and -400ER series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 767-25A0395, dated August 31, 2006; equipped with Goodrich door-mounted slide/rafts having P/Ns 5A3294-1, 5A3294-2, 5A3295-1, or 5A3295-3. As justification, Boeing states that this change clarifies that this AD applies only to certain Goodrich door-mounted slides/rafts. Boeing also states the applicability of the NPRM, as written, might require an alternative method of compliance (AMOC) for airplanes having other door-mounted slides/rafts. We agree to revise the applicability of this AD as requested by Boeing for the reasons stated above, except that paragraph (c) of this AD refers to Revision 1 of the service bulletin, dated January 25, 2007. Since we have added the affected part numbers for the discrepant door-mounted slides/rafts to the applicability of this AD, it is no longer necessary to require the inspection to determine the part numbers as specified in paragraph (f) of the NPRM. Therefore, we have deleted [[Page 59487]] that action and reidentified the subsequent paragraphs of this AD accordingly. Request To Delete Certain Airplanes From the Applicability Florida West International Airways states that this AD does not apply to Model 767-300GMF airplanes. We infer that the commenter requests that we delete that model designation from the applicability of this AD. We disagree because that model designation is not identified in the applicability of this AD. Model ``767-300GMF'' is not a valid designation as specified on the type certificate data sheet (TCDS) for Model 767 airplanes. Therefore, the commenter should verify the airplane identification as listed on the airplane data plate. This information will allow the commenter to determine whether this AD is applicable to its airplanes. We have not changed the AD in this regard. Request To Revise Paragraph (k)(1) of the NPRM Boeing requests that we revise paragraph (k)(1) of the NPRM as follows: ``* * * Determine if any door-mounted escape slide/raft having P/N 5A3294-1, 5A3294-2, 5A3295-1, or 5A3295-3 is installed; by review of the airplane maintenance records, or by a general visual inspection and modify the escape slide/rafts. Note the above slide/rafts may have been installed by Boeing Service Bulletin 767-25-0266.'' Boeing points out that this request also removes the following statement: ``Doing the inspection before the effective date of this AD in accordance with paragraph (f)(1) of this AD is acceptable for compliance with the inspection specified in this paragraph.'' As justification, Boeing states that its suggested changes focus the reader on the specific part numbers to be modified and assures that the escape slide/rafts inspected prior to the effective date of this new AD are modified. We agree to delete the second sentence of paragraph (k)(1) of the NPRM, since it is no longer necessary to provide relief for operators who, in accordance with paragraph (f)(1) of AD 2005-12-14, have previously inspected to determine if the discrepant slides/rafts are installed. However, we disagree with revising the first sentence of paragraph (k)(1) of the NPRM because Boeing's suggested changes and the language used in paragraph (j)(1) of this AD have essentially the same meaning. (As stated previously, paragraph (k) of the NPRM is reidentified as paragraph (j) in this AD.) Further, the language that we use is similar to what is stated in the Accomplishment Instructions of Boeing Alert Service Bulletin 767-25A0395, Revision 1. Conclusion We have carefully reviewed the available data, including the comments that have been received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance There are about 1,225 airplanes of the affected design in the worldwide fleet. This AD affects about 355 airplanes of U.S. registry. The actions that are required by AD 2005-12-14 and retained in this AD take up to 6 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the currently required actions for U.S. operators is $170,400, or is $480 per airplane. The new required actions take up to 6 work hours per airplane, at an average labor rate of $80 per work hour. The parts manufacturer states that it will supply the required parts to operators at no cost. Based on these figures, the estimated cost of the new actions specified in this AD for U.S. operators is $170,400, or $480 per airplane. 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 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. 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 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 AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
