Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-1419; Directorate Identifier 2014-NM-183-AD; 
Amendment 39-18279; AD 2015-20-01]
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 all 
Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 
188 series airplanes. This AD was prompted by an evaluation by the 
design approval holder (DAH) indicating the left and right lower 
surface panels of the wings are subject to widespread fatigue damage 
(WFD). This AD requires repetitive inspections for cracking at these 
panels, and repair if necessary. The AD also requires a one-time bolt-
hole eddy current inspection of all open holes for cracking, repair if 
necessary, and modification. We are issuing this AD to prevent fatigue 
cracking of the left and right lower surface panels of the wings, which 
could result in reduced structural integrity of the airplane.

DATES: This AD is effective November 13, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 13, 
2015.

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 all Lockheed Martin 
Corporation/Lockheed Martin Aeronautics Company Model 188 series 
airplanes. The NPRM published in the Federal Register on June 5, 2015 
(80 FR 32069). The NPRM was prompted by an evaluation by the DAH 
indicating the left and right lower surface panels of the wings are 
subject to WFD. The NPRM proposed to require repetitive inspections for 
cracking at these panels, and repair if necessary. The NPRM also 
proposed to require a one-time bolt-hole eddy current inspection of all 
open holes for cracking, repair if necessary, and modification. We are 
issuing this AD to prevent fatigue cracking of the left and right lower 
surface panels of the wings, which could result in reduced structural 
integrity of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 32069, June 5, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the available 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 (80 FR 32069, June 5, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM 80 FR 32069, June 5, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed Lockheed Martin Electra Service Bulletin 88/SB-707C, 
Revision C, dated April 30, 2014. The service information describes 
procedures for repetitive inspections for cracking of the left and 
right lower surface panels of the wings on the inboard and outboard 
sides of the buttock line (BL) 65 splice joint, and repair. This 
service information also describes procedures for a one-time bolt-hole 
eddy current inspection of all open holes for cracking, repair, and 
modification of the BL 65 wing root joint. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this AD.

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:

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.
