ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L– 1011–385–1, L–1011–385–1–14, L– 1011–385–1–15, and L–1011–385–3 airplanes. This AD was prompted by results from a damage tolerance analysis conducted by the manufacturer indicating that fatigue cracking could occur in wing rear spar and upper surface zones. This AD requires repetitive inspections for cracking of the wing rear spar and upper surface zones, and repair if necessary. We are issuing this AD to detect and correct such fatigue cracking, which could result in cracking that grows large enough to reduce the wing strength below certificated requirements and possibly cause fracture of the rear spar, resulting in extensive damage to the wing and possible fuel leaks. DATES: This AD is effective February 3, 2012. SUMMARY: The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of February 3, 2012.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on September 21, 2011 (76 FR 58416). That NPRM proposed to require repetitive inspections for cracking of the wing rear spar and upper surface zones, and repair if necessary. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 58416, September 21, 2011) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Interim Action We consider this AD interim action. If final action is later identified, we might consider further rulemaking then. Costs of Compliance We estimate that this AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Parts cost Labor cost Models: L–1011–385–1, L–1011–385– 1–14, L–1011–385–1–15, Zones 1A through 1E (Non-destructive Inspection).

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

[Docket No. FAA-2011-0919; Directorate Identifier 2010-NM-088-AD;
Amendment 39-16903; AD 2011-27-02]
RIN 2120-AA64

Airworthiness Directives; Lockheed Martin Corporation/Lockheed
Martin Aeronautics Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model
L-1011-385-1, L-1011-385-1-14, L-1011-385-1-15, and L-1011-385-3
airplanes. This AD was prompted by results from a damage tolerance
analysis conducted by the manufacturer indicating that fatigue cracking
could occur in wing rear spar and upper surface zones. This AD requires
repetitive inspections for cracking of the wing rear spar and upper
surface zones, and repair if necessary. We are issuing this AD to
detect and correct such fatigue cracking, which could result in
cracking that grows large enough to reduce the wing strength below
certificated requirements and possibly cause fracture of the rear spar,
resulting in extensive damage to the wing and possible fuel leaks.

DATES: This AD is effective February 3, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of February 3,
2012.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM published in the Federal Register on September 21, 2011 (76
FR 58416). That NPRM proposed to require repetitive inspections for
cracking of the wing rear spar and upper surface zones, and repair if
necessary.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 58416, September
21, 2011) or on the determination of the cost to the public.

Conclusion

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

Interim Action

We consider this AD interim action. If final action is later
identified, we might consider further rulemaking then.

Costs of Compliance

We estimate that this AD affects 4 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

We have received no definitive data that would enable us to provide
cost estimates 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

[[Page 82107]]

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.
