Federal Aviation Administration

14 CFR Part 39

[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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2011-27-02 Lockheed Martin Corporation/Lockheed Martin Aeronautics 
Company: Amendment 39-16903; Docket No. FAA-2011-0919; Directorate 
Identifier 2010-NM-088-AD.

 (a) Effective Date

    This AD is effective February 3, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to 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, certificated in any category, 
serial numbers 1002 through 1250 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Unsafe Condition

    This AD results from a damage tolerance analysis conducted by 
the manufacturer indicating that fatigue cracking could occur in 
wing rear spar and upper surface zones. 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.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspections of Wing Rear Spar and Upper Surface Zones, and 
Corrective Actions

    At the applicable time specified in paragraph (k) of this AD, do 
eddy current non-destructive inspections (NDI) and detailed 
inspections for cracking at the applicable zones specified in 
paragraph (g)(1) or (g)(2) of this AD, in accordance with the 
Accomplishment Instructions of Lockheed Service Bulletin 093-57-226, 
dated August 31, 2009. Repeat the inspections thereafter at the 
applicable interval specified in Table 1 of this AD.
    (1) For Model L-1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 
airplanes: Zones 1A through 1E, and Zone 1F.
    (2) For Model L-1011-385-3 airplanes: Zones 3A through 3E, and 
Zone 3F.

(h) Additional Inspection if Cracking Is Found

    Except as specified in paragraph (j) of this AD, if any cracking 
is detected during any inspection required by paragraph (g) of this 
AD: Before further flight, remove the fastener(s) at the suspect 
area, as defined in Lockheed Service Bulletin 093-57-226, dated 
August 31, 2009; and do a secondary eddy current inspection to 
detect cracking of fastener holes with suspected crack indications; 
in accordance with the Accomplishment Instructions of Lockheed 
Service Bulletin 093-57-226, dated August 31, 2009.

(i) Repair

    Except as specified in paragraph (j) of this AD, if a crack 
finding is confirmed by the inspection required by paragraph (h) of 
this AD and the cracking is within the allowable repair limits 
specified in Lockheed Martin Repair Drawing LCC-7622-369, Revision 
March 30, 1995: Before further flight, repair the cracking, in 
accordance with Lockheed Martin Repair Drawing LCC-7622-369, 
Revision March 30, 1995. If a crack finding confirmed by the 
inspection required by paragraph (h) of this AD is not within the 
allowable repair limits specified in Lockheed Martin Repair Drawing 
LCC-7622-369, Revision March 30, 1995: Before further flight, repair 
the cracking, in accordance with a method approved by the Manager, 
Atlanta Aircraft Certification Office (ACO), FAA. For a repair 
method to be approved by the Manager, Atlanta ACO, as required by 
this paragraph, the Manager's approval letter must specifically 
refer to this AD.

(j) Exception to Service Bulletin

    If any cracking is found during any inspection required by this 
AD, and Lockheed Service Bulletin 093-57-226, dated August 31, 2009; 
or Lockheed Martin Repair Drawing LCC-7622-369, Revision March 30, 
1995; specifies contacting Lockheed for appropriate action: Before 
further flight, repair the cracking in accordance with a method 
approved by the Manager, Atlanta ACO, FAA. For a repair method to be 
approved by the Manager, Atlanta ACO, as required by this paragraph, 
the Manager's approval letter must specifically refer to this AD.

(k) Compliance Times for Inspections

    Do the inspections required by paragraph (g) of this AD at the 
applicable time specified in table 1 of this AD.
