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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-09-
03, which applies to all Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes. AD 
2011-09-03 currently requires repetitive eddy current inspections to 
detect cracks in the center wing upper and lower rainbow fittings, and 
corrective actions if necessary; and repetitive replacement of rainbow 
fittings, which would extend the repetitive interval for the next 
inspection. Since we issued AD 2011-09-03, analysis of in-service 
cracking has shown that a reduction in the inspection intervals is 
necessary for the upper rainbow fittings. This proposed AD is intended 
to complete certain mandated programs intended to support the airplane 
reaching its limit of validity (LOV) of the engineering data that 
support the established structural maintenance program. This proposed 
AD would require reduced intervals for inspections of the upper rainbow 
fittings. We are proposing this AD to detect and correct fatigue 
cracking of the upper and lower rainbow fittings on the center wings, 
which could grow large and lead to the failure of the fitting and a 
catastrophic failure of the center wing.

DATES: We must receive comments on this proposed AD by November 3, 
2014.

Discussion

    On April 12, 2011, we issued AD 2011-09-03, Amendment 39-16665 (76 
FR 22311, April 21, 2011), for all Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G 
airplanes. AD 2011-09-03 requires repetitive eddy current inspections 
to detect cracks in the center wing upper and lower rainbow fittings, 
and corrective actions if necessary; and repetitive replacements of 
rainbow fittings, which would extend the repetitive interval for the 
next inspection. AD 2011-09-03 resulted from reports of fatigue 
cracking of the wing upper and lower rainbow fittings during durability 
testing and on in-service airplanes. Analysis of in-service cracking 
has shown that these rainbow fittings are susceptible to multiple site 
fatigue damage. We issued AD 2011-09-03 to detect and correct such 
fatigue cracks, which could grow large and lead to the failure of the 
fitting and a catastrophic failure of the center wing.

Actions Since AD 2011-09-03, Amendment 39-16665 (76 FR 22311, April 21, 
2011), Was Issued

    Since we issued AD 2011-09-03, Amendment 39-16665 (76 FR 22311, 
April 21, 2011), analysis of in-service cracking has shown that the 
initial and repetitive inspection schedules for the upper rainbow 
fitting need to be revised to reduce the probability of failure until 
the rainbow fitting is replaced.
    We have also revised paragraphs (i) and (k) of AD 2011-09-03, 
Amendment 39-16665 (76 FR 22311, April 21, 2011) to clarify the rainbow 
fitting is replaced with a new rainbow fitting, as specified in 
Lockheed Service Bulletin 382-57-82, Revision 4, including Appendixes A 
and B, dated May 20, 2009; and Lockheed Service Bulletin 382-57-82, 
including Appendices A and B, Revision 6, dated July 11, 2013.

Relevant Service Information

    We reviewed Lockheed Service Bulletin 382-57-82, including 
Appendices A, B, and C, Revision 6, dated July 11, 2013. The compliance 
times are reduced, but the procedures are unchanged from those 
described in Lockheed Service Bulletin 382-57-82, including Appendices 
A, B, and C, dated April 25, 2008.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain all of the requirements of AD 2011-
09-03, Amendment 39-16665 (76 FR 22311, April 21, 2011). This proposed 
AD would reduce compliance times for initial and repetitive inspections 
of the upper rainbow fitting.
    We have clarified the replacement process to more closely match the 
intent of the service information to replace affected fittings with new 
replacement fittings.

Differences Between This Proposed AD and the Service Information

    Where Lockheed Service Bulletin 382-57-82, including Appendices A, 
B, and C, Revision 6, dated July 11, 2013, does not specify a 
corrective action or states ``taking appropriate corrective action,'' 
this NPRM proposes to require repairing those conditions using a method 
approved by the Manager, Atlanta Aircraft Certification Office, FAA.

Costs of Compliance

    We estimate that this proposed AD affects 14 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    This proposed AD reduces the compliance times for the upper rainbow 
fitting inspections and adds no additional economic burden.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

effective date of this AD, only use Lockheed Service Bulletin 382-
57-82, including Appendix C, Revision 6, dated July 11, 2013, for 
accomplishing the actions specified in this paragraph.

(j) Retained Post-Replacement Repetitive Inspections

    This paragraph restates the requirements of paragraph (j) of AD 
2011-09-03, Amendment 39-16665 (76 FR 22311, April 21, 2011), with a 
new exception. For upper and lower rainbow fittings replaced in 
accordance with paragraph (i) or (k) of this AD: Except as required 
by paragraph (o) of this AD, do the eddy current inspections 
specified in paragraph (g) of this AD within 15,000 flight hours 
after doing the replacement and repeat the eddy current inspections 
specified in paragraph (h) of this AD thereafter at intervals not to 
exceed 3,600 flight hours until the rainbow fittings are replaced in 
accordance with paragraph (i) or (k) of this AD. Doing the 
requirements of paragraph (o) of this AD terminates the requirements 
of this paragraph for the affected upper rainbow fitting only.

(k) Retained Replacement, Related Investigative Actions, and Corrective 
Actions

    This paragraph restates the requirements of paragraph (k) of AD 
2011-09-03, Amendment 39-16665 (76 FR 22311, April 21, 2011), with 
revised service information and revised references to inspection 
paragraphs. If, during any inspection required by paragraph (g), 
(h), (m), or (n) of this AD, any crack is detected in the rainbow 
fitting, before further flight, replace the rainbow fitting with a 
new rainbow fitting, do all related investigative actions, and do 
all applicable corrective actions, in accordance with Paragraph 2.C. 
of the Accomplishment Instructions of Lockheed Service Bulletin 382-
57-82, Revision 4, including Appendix C, dated May 20, 2009, except 
as provided by paragraph (l) of this AD; or Lockheed Service 
Bulletin 382-57-82, including Appendix C, Revision 6, dated July 11,

revised service information. Where Lockheed Service Bulletin 382-57-
82, Revision 4, including Appendixes A, B, and C, dated May 20, 
2009; or Lockheed Service Bulletin 382-57-82, including Appendices 
A, B, and C, Revision 6, dated July 11, 2013; specifies to contact 
the manufacturer for disposition of certain repair conditions or 
does not specify corrective actions if certain conditions are found, 
this AD requires repairing those conditions using 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.

(m) New Requirement: Reduced Initial Compliance Time for Upper Rainbow 
Fittings

    At the applicable compliance time specified in paragraphs (m)(1) 
and (m)(2) of this AD, do eddy current inspections to detect 
cracking of the center wing upper rainbow fittings on the left and 
right side of the airplane. Do the actions in accordance with the 
Accomplishment Instructions of Lockheed Service Bulletin 382-57-82, 
including Appendices A and B, Revision 6, dated July 11, 2013. If 
any crack is found during the inspections required by this 
paragraph, before further flight, do the actions required by 
paragraph (k) of this AD. Doing the requirements of this paragraph 
terminates the requirements of paragraph (g) of this AD for that 
upper rainbow fitting only. Repeat the inspection at the interval 
required by paragraph (n) of this AD.
    (1) For upper rainbow fittings that have accumulated less than 
10,000 total flight hours as of the effective date of this AD, the 
compliance time is at the later of the times in paragraphs (m)(1)(i) 
and (m)(1)(ii) of this AD.
    (i) Before the accumulation of 10,000 total flight hours.
    (ii) Within 365 days or 600 flight hours after the effective 
date of this AD, whichever occurs first.
    (2) For upper rainbow fittings that have accumulated 10,000 
total flight hours or more, but less than 15,000 total flight hours 
as of the effective date of this AD, the compliance time is the 
earlier of the times specified in paragraphs (m)(2)(i) and 
(m)(2)(ii) of this AD.
    (i) Within 365 days or 600 flight hours after the effective date 
of this AD, whichever occurs first.
    (ii) Before the accumulation of 15,000 total flight hours on the 
rainbow fitting.

(n) New Requirement: Reduced Repetitive Inspection Intervals

    For upper rainbow fittings on which the requirements of 
paragraph (g), (h), or (m) of this AD were done, do the next 
inspection at the earlier of the times required in paragraphs (n)(1) 
and (n)(2) of this AD. Thereafter, repeat the inspection required by 
paragraph (m) of this AD at intervals not to exceed 2,500 flight 
hours until the upper rainbow fitting has accumulated 30,000 total 
flight hours. If any crack is found during the inspections required 
by this paragraph, before further flight, do the actions required by 
paragraph (k) of this AD. Doing an inspection required by this 
paragraph terminates the requirements of paragraph (h) of this AD 
for the affected upper rainbow fitting only.
    (1) Within 3,600 flight hours since the last inspection done in 
accordance with paragraph (g), (h), or (m) of this AD, whichever 
occurs latest.
    (2) At the later of the times specified in paragraphs (n)(2)(i) 
and (n)(2)(ii) of this AD.
    (i) Within 2,500 flight hours after the last inspection done in 
accordance with paragraph (g), (h), or (m) of this AD, whichever 
occurs latest.
    (ii) Within 365 days or 600 flight hours after the effective 
date of this AD, whichever occurs first.

(o) New Requirement: Reduced Post-Replacement Repetitive Inspections

    For upper rainbow fittings replaced in accordance with paragraph 
(i) or (k) of this AD, do the inspection required by paragraph (m) 
of this AD at the earlier of the compliance times required in 
paragraph (o)(1) and (o)(2) of this AD. Repeat the inspection 
thereafter at intervals not to exceed 2,500 flight hours. Doing the 
inspections required by this paragraph terminates the requirements 
of paragraph (j) of this AD for the affected upper rainbow fitting 
only.
    (1) At the later of the times in paragraphs (o)(1)(i) and 
(o)(1)(ii) of this AD. (i) Within 10,000 total flight hours on the 
upper rainbow fitting.
    (ii) Within 365 days or 600 flight hours after the effective 
date of this AD, whichever occurs first.
    (2) Within 15,000 total flight hours on the upper rainbow 
fitting.
