Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes. This AD was prompted by two in-
service occurrences on Model 737-400 airplanes of total loss of boost pump pressure of the fuel feed system, followed by loss of fuel system suction feed capability on one engine, and in-flight shutdown of the engine. This AD requires repetitive operational tests of the engine fuel suction feed of the fuel system, and corrective actions if necessary. We are issuing this AD to detect and correct loss of the engine fuel suction feed capability of the fuel system, which, in the event of total loss of the fuel boost pumps, could result in dual engine flameout, inability to restart the engines, and consequent forced landing of the airplane.
DATES: This AD is effective October 1, 2013.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of October 1, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. The SNPRM published in the Federal Register on October 30, 2012 (77 FR 65642). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on June 6, 2008 (73 FR 32256). The NPRM proposed to require repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary, according to a method approved by the FAA. The SNPRM proposed to require repetitive operational tests of the engine fuel suction feed of the fuel system, and corrective actions if necessary.
Comments
We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the SNPRM (77 FR 65642, October 30, 2012) and the FAA's response to each comment.
Support for the SNPRM (77 FR 65642, October 30, 2012)
One commenter, Mara Essick, submitted support for the actions specified in the SNPRM (77 FR 65642, October 30, 2012).

Request To Provide Credit for Actions Done Before Service Bulletin Issued
American Airlines (AA) asked that we give credit for operators that accomplished the specified actions before issuance of Boeing Alert Service Bulletin 757-28A0131, dated May 4, 2012. AA stated that it accomplished the operational tests proposed in the original NPRM (73 FR 32256, June 6, 2008) in 2008, using the Boeing task cards or airplane maintenance manual (AMM). AA added that it continues to do the repetitive operational tests at intervals not to exceed 7,500 flight hours.
We do not agree with the commenter's request. Although we normally support granting credit for accomplishing actions prior to the effective date of the AD, the credit is generally given using a previous issue of the required service bulletin, not for an AMM or task cards. Under the provisions of paragraph (h) of this final rule, however, we may consider individual requests for credit for accomplishing actions prior to the effective date of the AD if data are submitted to substantiate that it provides an acceptable level of safety. We have made no change to the AD in this regard.
Conclusion
We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed.
Costs of Compliance
We estimate that this AD affects 673 airplanes of U.S. registry. We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Operational Test..................... Up to 6 work hours x Up to $2,040, per test. Up to $343,230, per
$85 per hour = $510 test
per engine, per test.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this 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
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
