14 CFR Part 39

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 series airplanes. This AD was prompted by reports of cracked rib 
cap castellations. This AD requires repetitive inspections for 
castellation and skin clips cracked or damaged between stringers and 
cracked stringer clips of the wing box pylon back-up structure, and 
front spar to rear spar; repetitive inspections for cracking, damage, 
or failure of the pylon back-up torque box structure; repetitive 
inspections for cracking or damage of the wing box external areas at 
the drag brace aft wing fitting; repetitive inspections of the outer 
surface of the wing upper and lower skins for cracks or damage along 
the rib attachment at the fastener holes and between the two rows of 
attachment; and corrective actions if necessary. We are issuing this AD 
to detect and correct cracked or damaged rib cap castellations, which 
could degrade the structural capabilities of the airplane.

DATES: This AD is effective November 7, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 7, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Lockheed Martin 
Corporation/Lockheed Martin Aeronautics Company Model L-1011 series 
airplanes. The NPRM published in the Federal Register on May 29, 2014 
(79 FR 30748). The NPRM was prompted by reports of cracked rib cap 
castellations. The NPRM proposed to require repetitive inspections for 
castellation and skin clips cracked or damaged between stringers and 
cracked stringer clips of the wing box pylon back-up structure, and 
front spar to rear spar; repetitive inspections for cracking, damage, 
or failure of the pylon back-up torque box structure; repetitive 
inspections for cracking or damage of the wing box external areas at 
the drag brace aft wing fitting; repetitive inspections of the outer 
surface of the wing upper and lower skins for cracks or damage along 
the rib attachment at the fastener holes and between the two rows of 
attachment; and corrective actions if necessary. We are issuing this AD 
to detect and correct cracked or damaged rib cap castellations, which 
could degrade the structural capabilities of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 30748, May 29, 
2014) 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 this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 30748, May 29, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 30748, May 29, 2014).

Costs of Compliance

    We estimate that this AD affects 26 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

[[Page 59644]]

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the inspections. We have no 
way of determining the number of aircraft that might need these 
repairs:

                                               On-Condition Costs

                                        cap.
----------------------------------------------------------------------------------------------------------------

    Other than the modification stated above, we have received no 
definitive data that would enable us to provide cost estimates for the 
crack repair actions specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.

whichever occurs first, for that rib cap only.

(i) Corrective Actions

    If any cracking, damage, or failure is found during any

flight, do all applicable corrective actions, in accordance with the 
Accomplishment Instructions of Lockheed Martin Service Bulletin 093-
57-207, Revision 5, dated November 14, 2008, except where this 
service bulletin specifies that all other damaged structural items 
should be repaired using the best shop practices, following 
procedures in Structural Repair Manual 57-12-00, this AD requires

this AD: Submit the report within 30 days after the inspection.
    (2) If the inspection was done before the effective date of this
