Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION:
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/corrective actions if necessary. This AD results from a report of chafing in this area. We are issuing this AD to detect and correct such chafing or scoring, which could result in reduced structural integrity of the fuselage. DATES:
This AD becomes effective November 2, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of November 2, 2006. ADDRESSES:

Examining the Docket You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. Discussion The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. That supplemental NPRM was published in the Federal Register on April 5, 2006 (71 FR 17037). That supplemental NPRM proposed to require repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/corrective actions if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment we received on the supplemental NPRM. Request for Revised Compliance Time BAE notes that corresponding British airworthiness directive G-2005-0020, dated July 6, 2005, allows an additional 4,000 flight cycles before previously inspected airplanes must be reinspected. But paragraph (f) of the supplemental NPRM would require all airplanes to be inspected before the airplane accumulates 1,000 total flight cycles, or within a grace period of 500 flight cycles, without any provision for an extended compliance time for airplanes previously inspected in accordance with both BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005, Revision 2, dated February 16, 2005, and ISB.53-067, Revision 3, dated June 27, 2005. BAE adds that there are no airplanes in service with fewer than 1,000 total flight cycles. We infer that the commenter requests that we revise the supplemental NPRM. We agree. We have revised paragraph (f) to allow the deferral of certain corrective actions under specific conditions outlined in the service bulletins, as provided in new paragraph (h) in this AD. Additional Changes to Supplemental NPRM The supplemental NPRM specified that all actions including corrective actions would be required at the times specified in BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-005 and ISB.53-067. Our intent was to match the specifications of the service bulletins, which allow deferred corrective action only under certain conditions. To clarify the required compliance times of this AD, we have added new paragraph (h) to explicitly require corrective actions before further flight, except when repair may be deferred under the specific conditions noted in the service bulletins. Paragraph (g) of the supplemental NPRM specified making repairs using a method approved by either the FAA or the Civil Aviation Authority, which is the airworthiness authority for the United Kingdom. The European Aviation Safety Agency (EASA) has assumed responsibility for the airplane model subject to this AD. Therefore, we have revised paragraph (g) of this AD to specify making repairs using a method approved by the FAA, the CAA (or its delegated agent), or the EASA (or its delegated agent). Conclusion We have carefully reviewed the available data, including the comments 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.

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.
