SUPPLEMENTARY INFORMATION: DEPARTMENT OF TRANSPORTATION Discussion Federal Aviation Administration We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2007–05–17, Amendment 39–14978 (72 FR 10350, March 8, 2007). That AD applies to the specified products. That NPRM published in the Federal Register on November 22, 2011 (76 FR 72130). That NPRM proposed to continue to require revisions to the ALS of the manufacturer’s ICA to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. That NPRM also proposed to require additional revisions to the JT9D series engines ALS sections of the manufacturer’s ICA. 14 CFR Part 39 [Docket No. FAA–2007–27023; Directorate Identifier 98–ANE–47–AD; Amendment 39– 16971; AD 2012–04–15] RIN 2120–AA64 Airworthiness Directives; Pratt & Whitney Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for all Pratt & Whitney (PW) JT9D series turbofan engines. That AD currently requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer’s Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part opportunity. This new AD requires additional revisions to the JT9D series engines ALS sections of the manufacturer’s ICA. This AD was prompted by the need to require enhanced inspection of selected critical life-limited parts of JT9D series engines. We are issuing this AD to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane. DATES: This AD is effective April 23, 2012. emcdonald on DSK29S0YB1PROD with RULES SUMMARY: ADDRESSES: VerDate Mar<15>2010 11:27 Mar 16, 2012 Jkt 226001 Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that 438 JT9D series engines are installed on airplanes of U.S. registry and will be affected by this AD. We also estimate that about 4 work hours per engine are needed to perform the actions, and that the average labor rate is $85 per work hour. Since this is an added inspection requirement that will be part of the normal maintenance cycle, no additional parts costs are involved. Based on these figures, we PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 15939 estimate the total cost of the AD to U.S. operators to be $148,920. 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.

Airworthiness Directives; Pratt & Whitney Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Pratt & Whitney (PW) JT9D series turbofan engines. That AD 
currently requires revisions to the Airworthiness Limitations Section 
(ALS) of the manufacturer's Instructions for Continued Airworthiness 
(ICA) to include required enhanced inspection of selected critical 
life-limited parts at each piece-part opportunity. This new AD requires 
additional revisions to the JT9D series engines ALS sections of the 
manufacturer's ICA. This AD was prompted by the need to require 
enhanced inspection of selected critical life-limited parts of JT9D 
series engines. We are issuing this AD to prevent critical life-limited 
rotating engine part failure, which could result in an uncontained 
engine failure and damage to the airplane.

DATES: This AD is effective April 23, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2007-05-17, Amendment 39-14978 (72 FR 10350, 
March 8, 2007). That AD applies to the specified products. That NPRM 
published in the Federal Register on November 22, 2011 (76 FR 72130). 
That NPRM proposed to continue to require revisions to the ALS of the 
manufacturer's ICA to include required enhanced inspection of selected 
critical life-limited parts at each piece-part opportunity. That NPRM 
also proposed to require additional revisions to the JT9D series 
engines ALS sections of the manufacturer's ICA.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM.

Conclusion

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

Costs of Compliance

    We estimate that 438 JT9D series engines are installed on airplanes 
of U.S. registry and will be affected by this AD. We also estimate that 
about 4 work hours per engine are needed to perform the actions, and 
that the average labor rate is $85 per work hour. Since this is an 
added inspection requirement that will be part of the normal 
maintenance cycle, no additional parts costs are involved. Based on 
these figures, we estimate the total cost of the AD to U.S. operators 
to be $148,920.

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.
