14 CFR Part 39

[Docket No. FAA-2007-0096; Directorate Identifier 2007-NE-39-AD; 
Amendment 39-16141; AD 2009-26-06]
RIN 2120-AA64

 
Airworthiness Directives; Honeywell International Inc. ALF502 
Series and LF507 Series Turbofan Engines

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Honeywell International Inc. ALF502 series and LF507 series 
turbofan engines with certain fuel manifold assemblies installed. That 
AD currently requires initial and repetitive on-wing eddy current or 
in-shop fluorescent penetrant inspections of certain part number (P/N) 
fuel manifold assemblies for cracks, and replacement of cracked fuel 
manifolds with serviceable manifolds. This AD continues to require 
inspecting those fuel manifolds for cracks, adds leak checks of certain 
additional P/N fuel manifolds, and specifies replacement of the 
affected manifolds as an optional terminating action in lieu of the 
repetitive inspections. This AD results from reports of fire in the 
engine nacelle. We are issuing this AD to detect cracks in certain fuel 
manifolds and fuel leaks from other fuel manifolds, which could result 
in a fire in the engine nacelle and a hazard to the aircraft.

DATES: This AD becomes effective February 11, 2010. The Director of the 
Federal Register approved the incorporation by reference of 
AlliedSignal Service Bulletin (SB) ALF/LF 73-1002, Revision 1, dated 
March 24, 1997, listed in this AD as of February 11, 2010. The Director 
of the Federal Register previously approved the incorporation by 
reference of SB ALF/LF 73-1002, dated December 22, 1995, listed in this 
AD as of July 28, 1997 (62 FR 28994, May 29, 1997).

Angeles Aircraft Certification Office, FAA, Transport Airplane 
Directorate, 3960 Paramount Blvd., Lakewood, CA 90712-4137; e-mail:

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 by 
superseding AD 97-11-05, Amendment 39-10034 (62 FR 28994, May 29, 
1997), with a proposed AD. The proposed AD applies to Honeywell 
International Inc. ALF502 series and LF507 series turbofan engines with 
certain fuel manifold assemblies installed. We published the proposed 
AD in the Federal Register on April 13, 2009 (74 FR 16803). That action 
proposed to continue to require inspecting those fuel manifolds for 
cracks, would also add leak checks of certain additional P/N fuel 
manifolds, and would specify replacement of the affected manifolds as 
an optional terminating action in lieu of the repetitive inspections.

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 this AD, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is provided in 
the ADDRESSES section. Comments will be available in the AD docket 
shortly after receipt.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the proposal or on 
the determination of the cost to the public.

Clarification in Optional Terminating Action Paragraph

    Paragraph (i) of this AD is partially revised from, ``* * * 
terminates the repetitive inspection requirement specified in 
paragraphs (f)(1)(iii), (f)(2)(iii), (g), and (h) of this AD.'' to ``* 
* * terminates the inspection requirement of this AD.'' This change was 
made because replacing a fuel manifold assembly that has a P/N 
specified in paragraph (i) of this AD, or an FAA-approved equivalent 
part, terminates all inspection requirements of this AD.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    We estimate that this AD will affect 156 engines installed on 
airplanes of U.S. registry. We also estimate that it will take about 7 
work-hours per engine to perform the required actions, and that the 
average labor rate is $80 per work-hour. Required parts will cost about 
$50,000 per engine. Based on these figures, we estimate the total cost 
of this AD to U.S. operators to be $7,887,360.

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.

[[Page 902]]

    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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.
