FOR FURTHER INFORMATION CONTACT: 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. That SNPRM was published in the Federal Register on July 17, 2012 (77 FR 41934). The original NPRM (73 FR 32245, June 6, 2008) proposed to require performing repetitive operational tests of the engine fuel suction feed of the fuel system, and other related testing if necessary. The SNPRM proposed to require repetitive operational tests, and corrective actions if necessary. Comments We gave the public the opportunity to participate in developing this AD. We 64705 have considered the comment received from a single commenter: Boeing concurs with the content of the SNPRM (77 FR 41934, July 17, 2012). Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD will affect 1,080 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Cost per product Action Labor cost Operational Test ..................... 3 work hours × $85 per hour = $255 per engine, per test ...... We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions or the optional terminating action 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. tkelley on DSK3SPTVN1PROD with RULES 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 VerDate Mar<15>2010 16:04 Oct 22, 2012 Jkt 229001 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.

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. That SNPRM was published in the 
Federal Register on July 17, 2012 (77 FR 41934). The original NPRM (73 
FR 32245, June 6, 2008) proposed to require performing repetitive 
operational tests of the engine fuel suction feed of the fuel system, 
and other related testing if necessary. The SNPRM proposed to require 
repetitive operational tests, and corrective actions if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received from a single 
commenter: Boeing concurs with the content of the SNPRM (77 FR 41934, 
July 17, 2012).

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Costs of Compliance

    We estimate that this AD will affect 1,080 airplanes of U.S. 
registry. We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                           Cost per
             Action                    Labor cost          product              Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Operational Test...............  3 work hours x $85 per         $255  $275,400 per engine, per test.
                                  hour = $255 per
                                  engine, per test.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions or the optional 
terminating action 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.

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 2800, Aircraft Fuel System.

(e) Unsafe Condition

    This AD was prompted by reports of 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. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Operational Test and Corrective Actions

    Within 30,000 flight hours after the effective date of this AD: 
Perform an operational test of the engine fuel suction

feed of the fuel system, and all applicable corrective actions, in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin 747-28A2331, dated April 2, 2012. Do all applicable 
corrective actions before further flight. Repeat the operational 
test thereafter at intervals not to exceed 30,000 flight hours. 
Thereafter, except as provided in paragraph (h) of this AD, no 
alternative procedure or repetitive test intervals will be allowed.
