AGENCY: VerDate Mar<15>2010 17:50 Dec 29, 2011 Jkt 226001 ACTION: Final rule. We are revising an existing airworthiness directive (AD) for Thielert Aircraft Engines GmbH models TAE 125–02–99 and TAE 125–01 reciprocating engines. That AD currently requires replacing the existing rail pressure control valve with an improved rail pressure control valve. This new AD requires the same actions but relaxes the initial compliance time from within 100 flight hours to within 600 flight hours for TAE 125–01 reciprocating engines. This AD was prompted by the determination that our AD was inadvertently more restrictive than European Aviation Safety Agency AD 2008–0128. We are issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft. DATES: This AD is effective February 3, 2012.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 2010–06–12, Amendment 39–16236 (75 FR 12439, PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 March 16, 2010). That AD applies to the specified products. The NPRM published in the Federal Register on October 18, 2011 (76 FR 64285). That NPRM proposed to require relaxing the initial compliance time from within 100 flight hours to within 600 flight hours for TAE 125–01 reciprocating engines. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. Clarification of the VRail Plug Modification Since we issued the NPRM, we determined that the compliance paragraph describing the Vrail plug modification needed clarification. We changed paragraph (e)(1)(i) in the AD to describe what existing parts need to be removed and what part number needs to be installed. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD with the change described previously. Costs of Compliance Based on the service information, we estimate that this AD will affect about 370 TAE 125–01 and TAE 125–02–99 reciprocating engines installed on products of U.S. registry. We also estimate that it will take about 1.5 workhours per engine to comply with this AD. The average labor rate is $85 per work-hour. Required parts will cost about $500 per engine. Based on these figures, we estimate the cost of the AD for initial replacement on U.S. operators to be $232,175. 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 E:\FR\FM\30DER1.SGM 30DER1 Federal Register / Vol. 76, No. 251 / Friday, December 30, 2011 / Rules and Regulations 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. 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 notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to revise AD 2010-06-12, Amendment 39-16236 (75 FR 12439, March 
16, 2010). That AD applies to the specified products. The NPRM 
published in the Federal Register on October 18, 2011 (76 FR 64285). 
That NPRM proposed to require relaxing the initial compliance time from 
within 100 flight hours to within 600 flight hours for TAE 125-01 
reciprocating engines.

Comments

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

Clarification of the VRail Plug Modification

    Since we issued the NPRM, we determined that the compliance 
paragraph describing the Vrail plug modification needed clarification. 
We changed paragraph (e)(1)(i) in the AD to describe what existing 
parts need to be removed and what part number needs to be installed.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD with the change described 
previously.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 370 TAE 125-01 and TAE 125-02-99 reciprocating engines 
installed on products of U.S. registry. We also estimate that it will 
take about 1.5 work-hours per engine to comply with this AD. The 
average labor rate is $85 per work-hour. Required parts will cost about 
$500 per engine. Based on these figures, we estimate the cost of the AD 
for initial replacement on U.S. operators to be $232,175.

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.
    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.
