Examining the AD Docket [Docket No. FAA–2016–9490; Directorate Identifier 2016–NE–26–AD] RIN 2120–AA64 Airworthiness Directives; General Electric Company Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) CF6– 80C2L1F turbofan engines. This proposed AD was prompted by a reduction in the life limit of the affected engines which is the result of a revised operating profile. This proposed AD would require replacement of the highpressure turbine (HPT) spacer/impeller, part number (P/N) 1539M12P02, at a newer, lower life limit. We are proposing this AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by March 9, 2017.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The United States Air Force revised its operating profile for its GE CF6– 80C2L1F engines. As a result of this change in operating profile, GE reduced its life limit for the HPT spacer/impeller from 20,000 to 18,000 cycles. Therefore, we are proposing to require removal of this affected HPT spacer/impeller at the new, lower life limit. This condition, if not corrected, could result in failure of the HPT spacer/impeller, uncontained release of the HPT spacer/impeller, damage to the engine, and damage to the airplane. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require replacement of the HPT spacer/impeller, P/N 1539M12P02, at a newer, lower life limit. Costs of Compliance We estimate that this proposed AD affects 0 engines installed on airplanes of U.S. registry.

Airworthiness Directives; General Electric Company Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain General Electric Company (GE) CF6-80C2L1F turbofan engines. 
This proposed AD was prompted by a reduction in the life limit of the 
affected engines which is the result of a revised operating profile. 
This proposed AD would require replacement of the high-pressure turbine 
(HPT) spacer/impeller, part number (P/N) 1539M12P02, at a newer, lower 
life limit. We are proposing this AD to correct the unsafe condition on 
these products.

Directorate Identifier 2016-NE-26-AD'' at the beginning of your

Discussion

    The United States Air Force revised its operating profile for its 
GE CF6-80C2L1F engines. As a result of this change in operating 
profile, GE reduced its life limit for the HPT spacer/impeller from 
20,000 to 18,000 cycles. Therefore, we are proposing to require removal 
of this affected HPT spacer/impeller at the new, lower life limit. This 
condition, if not corrected, could result in failure of the HPT spacer/
impeller, uncontained release of the HPT spacer/impeller, damage to the 
engine, and damage to the airplane.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require replacement of the HPT spacer/
impeller, P/N 1539M12P02, at a newer, lower life limit.

Costs of Compliance

    We estimate that this proposed AD affects 0 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 7735]]

    For the reasons discussed above, I certify this proposed 
regulation:
    (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),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, 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.
