[Federal Register: September 29, 2008 (Volume 73, Number 189)] [Rules and Regulations] [Page 56462-56464] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr29se08-7] [[Page 56462]] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2008-0361; Directorate Identifier 2007-NM-279-AD; Amendment 39-15681; AD 2008-20-02] RIN 2120-AA64 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 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) originated 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: A few hydraulic system tube clamps located inside the wing fuel tanks were found damaged. Further analysis has shown that damage to multiple clamps may cause sparks inside the tanks, which in turn may lead to ignition of flammable vapors inside the fuel tanks. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective November 3, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of November 3, 2008. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Kenny Kaulia, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, Washington 98057-3356; telephone (425) 227-2848; fax (425) 227-1149. 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 March 28, 2008 (73 FR 16575). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: A few hydraulic system tube clamps located inside the wing fuel tanks were found damaged. Further analysis has shown that damage to multiple clamps may cause sparks inside the tanks, which in turn may lead to ignition of flammable vapors inside the fuel tanks. The corrective action includes replacing tube attachment clamps having certain part numbers with new tube attachment clamps. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Add Revised Service Information EMBRAER states that Service Bulletin 170-29-0006 was revised to include additional airplanes in the effectivity. Therefore, EMBRAER recommends that the AD applicability refers to Service Bulletin 170-29- 0006, Revision 01, dated February 22, 2008. The original issue, dated October 4, 2006, was referred to in the NPRM as the source of service information for accomplishing certain actions. EMBRAER adds that the original issue should be kept as an acceptable means of compliance. We agree that the applicability in the NPRM should be changed. Revision 01 of the service bulletin includes a reference to ``EMBRAER 175 ( ) model aircraft,'' which is the marketing designation for a certain version of the Model ERJ 170 airplane. However, no additional airplanes have been added to the service bulletin effectivity. We have changed the service bulletin reference in paragraph (c) of this AD from the original issue to Revision 01. In addition, we agree to change paragraph (f) of the AD to refer to Revision 01 of the referenced service bulletin. Revision 01 specifies that there is no additional action for airplanes on which the actions in the original issue of the service bulletin have been done. We have also added a new paragraph (f)(3) to this AD to give operators credit for doing the actions in the original issue of the service bulletin. Request To Change Paragraph (e) EMBRAER also recommends changing paragraph (e) of the NPRM to add the phrase, ``in conjunction with a lightning strike'' following the words ``multiple clamps'' as specified in that paragraph. EMBRAER did not provide a justification for this change. We do not agree that paragraph (e) of the NPRM should be changed. Paragraph (e) of this AD quotes the requirements in the MCAI verbatim; therefore, no change to the AD is necessary in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. 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 our FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 88 products of U.S. registry. We also estimate that it will take 18 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $269 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $150,392, or about $1,709 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. [[Page 56463]] 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 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 AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office 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 Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
