[Federal Register: September 12, 2007 (Volume 72, Number 176)] [Rules and Regulations] [Page 51996-51997] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr12se07-6] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2007-27865 Directorate Identifier 2007-CE-039-AD; Amendment 39-15191; AD 2007-19-01] RIN 2120-AA64 Airworthiness Directives; Pacific Aerospace Corporation, Ltd. Model 750XL Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: To prevent the cockpit door windows separating from their frames, * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective October 17, 2007. On October 17, 2007, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590. FOR FURTHER INFORMATION CONTACT: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090. SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on July 9, 2007 (72 FR 37124). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: To prevent the cockpit door windows separating from their frames, * * * The MCAI requires you to inspect the windscreen and cockpit door windows for signs of disbonding of the adhesive between the transparency and the composite window frame. If disbonding is evident, you must do the required modification. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 7 products of U.S. registry. We also estimate that it will take about 40 work-hours per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $50 per product. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $22,750 or $3,250 per product. 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 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 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. Examining the AD Docket You may examine the AD docket on the Internet at http://dms.dot.gov ; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment 0 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: [[Page 51997]] PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2007-19-01 Pacific Aerospace Corporation, Ltd: Amendment 39-15191; Docket No. FAA-2007-27865; Directorate Identifier 2007-CE-039-AD. Effective Date (a) This airworthiness directive (AD) becomes effective October 17, 2007. Affected ADs (b) None. Applicability (c) This AD applies to Model 750XL airplanes, all serial numbers, certificated in any category, that have not incorporated Pacific Aerospace Limited Service Letter PACSL/XL/07-1, dated April 18, 2007, with Pacific Aerospace LTD Drawing, 11-03129, Issue B or subsequent, in its entirety. Subject (d) Air Transport Association of America (ATA) Code 56: Windows. Reason (e) The mandatory continuing airworthiness information (MCAI) states: To prevent the cockpit door windows separating from their frames, * * * The MCAI requires you to inspect the windscreen and cockpit door windows for signs of disbonding of the adhesive between the transparency and the composite window frame. If disbonding is evident, you must do the required modification. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 50 hours time-in-service (TIS) after October 17, 2007 (the effective date of this AD) and thereafter at intervals not to exceed 50 hours TIS, inspect the windscreen and cockpit door windows for signs of disbonding of the adhesive between the transparency and the composite window frame following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and PAC Drawing No. 11- 03137, both dated February 20, 2007 (undated). If you find disbanding during any inspection required by this AD, before further flight, modify the windscreen and cockpit windows to incorporate mechanical fasteners following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/ 0276) and PAC Drawing No. 11-03137 both dated February 20, 2007. (2) Within the next 150 hours TIS after October 17, 2007 (the effective date of this AD) or within the next 6 months after October 17, 2007 (the effective date of this AD), whichever occurs first, modify the windscreen and cockpit windows to incorporate mechanical fasteners following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/024 (embodiment of modification PAC/XL/0276) and PAC Drawing No. 11-03137 both dated February 20, 2007. The requirement of paragraph (f)(1) of this AD to do repetitive inspections is no longer necessary when the modification of paragraph (f)(2) of this AD is done. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
