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-
04, which applies to all Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes. AD 
2011-09-04 currently requires repetitive inspections for any damage of 
the lower surface of the center wing box, and corrective actions if 
necessary. Since we issued AD 2011-09-04, an evaluation by the design 
approval holder (DAH) indicated that the center wing box is subject to 
widespread fatigue damage (WFD). This proposed AD would also require 
replacement of the center wing box, which would terminate the 
repetitive inspections. This proposed AD would also add a concurrent 
related investigative action. We are proposing this AD to detect and 
correct fatigue cracking of the lower surface of the center wing box, 
which could result in structural failure of the wings.

DATES: We must receive comments on this proposed AD by August 15, 2014.

Discussion

    Structural fatigue damage is progressive. It begins as minute 
cracks, and those cracks grow under the action of repeated stresses. 
This can happen because of normal operational conditions and design 
attributes, or because of isolated situations or incidents such as 
material defects, poor fabrication quality, or corrosion pits, dings, 
or scratches. Fatigue damage can occur locally, in small areas or 
structural design details, or globally. Global fatigue damage is 
general degradation of large areas of structure with similar structural 
details and stress levels. Multiple-site damage is global damage that 
occurs in a large structural element such as a single rivet line of a 
lap splice joining two large skin panels. Global damage can also occur 
in multiple elements such as adjacent frames or stringers. Multiple-
site-damage and multiple-element-damage cracks are typically too small 
initially to be reliably detected with normal inspection methods. 
Without intervention, these cracks will grow, and eventually compromise 
the structural integrity of the airplane, in a condition known as 
widespread fatigue damage (WFD). As an airplane ages, WFD will likely 
occur, and will certainly occur if the airplane is operated long enough 
without any intervention.
    The FAA's WFD final rule (75 FR 69746, November 15, 2010) became 
effective on January 14, 2011. The WFD rule requires certain actions to 
prevent structural failure due to WFD throughout the operational life 
of certain existing transport category airplanes and all of these 
airplanes that will be certificated in the future. For existing and 
future airplanes subject to the WFD rule, the rule requires that DAHs 
establish a limit of validity (LOV) of the engineering data that 
support the structural maintenance program. Operators affected by the 
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV 
is approved.
    The WFD rule (75 FR 69746, November 15, 2010) does not require 
identifying and developing maintenance actions if the DAHs can show 
that such actions are not necessary to prevent WFD before the airplane 
reaches the LOV. Many LOVs, however, do depend on accomplishment of 
future maintenance actions. As stated in the WFD rule, any maintenance 
actions necessary to reach the LOV will be mandated by airworthiness 
directives through separate rulemaking actions.
    In the context of WFD, this action is necessary to enable DAHs to 
propose LOVs that allow operators the longest operational lives for 
their airplanes, and still ensure that WFD will not occur. This 
approach allows for an implementation strategy that provides 
flexibility to DAHs in determining the timing of service information 
development (with FAA approval), while providing operators with 
certainty regarding the LOV applicable to their airplanes.
    On April 12, 2011, we issued AD 2011-09-04, Amendment 39-16666 (76 
FR 28626, May 18, 2011), for all Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G 
airplanes. AD 2011-09-04 requires repetitive inspections for any damage 
of the lower surface of the center wing box, and corrective actions if 
necessary. AD 2011-09-04 resulted from reports of fatigue cracks of the 
lower surface of the center wing box. We issued AD 2011-09-04 to detect 
and correct such cracks, which could result in the structural failure 
of the wings.

Actions Since AD 2011-09-04 Was Issued

    Since we issued AD 2011-09-04, Amendment 39-16666 (76 FR 28626, May 
18, 2011), the DAH completed an evaluation that indicated removal of a 
recurring inspection, establishment of a terminating action, and 
reference to certain center wing box replacement service information is 
necessary to safeguard the airplane against WFD up to the LOV of the 
airplane.

Relevant Service Information

    We reviewed Lockheed Service Bulletin 382-57-85 (82-790), Revision 
3, dated July 8, 2013, including Appendix A, dated July 8, 2013, and 
Appendixes B, C, D, E, F, and G, all Revision 1, all dated March 8, 
2007. This service information is essentially the same as Lockheed 
Service Bulletin 382-57-85 (82-790), Revision 2, dated August 23, 2007, 
including Appendixes A, B, C, D, E, F, and G, all Revision 1, all dated 
March 8, 2007, which is referred to as the appropriate source of 
service information in AD 2011-09-04, Amendment 39-16666 (76 FR 28626, 
May 18, 2011). Revision 3 adds a concurrent related investigative 
action, which involves a bolt hole eddy current inspection for cracking 
at additional fastener locations.
    We also reviewed Lockheed Service Bulletin 382-57-94, dated 
December 3, 2013, which describes procedures for replacement of the 
center wing box. Accomplishing the replacement eliminates the need for 
repetitive inspections.

Other Relevant Rulemaking

    Accomplishing the replacement of the center wing box specified in 
paragraph (k) of this proposed AD affects the requirements of the 
following ADs:
     AD 2011-09-03, Amendment 39-16665 (77 FR 22311, April 21, 
2011), which 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. We issued this AD to detect and correct fatigue cracks, 
which could grow large and lead to the failure of the fitting and a 
catastrophic failure of the center wing.
     AD 2011-15-02, Amendment 39-16749 (76 FR 41647, July 15, 
2011), which superseded AD 2008-20-01, Amendment 39-15680 (73 FR 56464, 
September 29, 2008). AD 2011-15-02 continues to require revising the 
maintenance program by incorporating

[[Page 37250]]

new airworthiness limitations for fuel tank systems to satisfy the 
requirements of Special Federal Aviation Regulation (SFAR) No. 88 
(``SFAR 88,'' Amendment 21-78, and subsequent Amendments 21-82 and 21-
83), which is part of a regulation titled ``Transport Airplane Fuel 
Tank System Design Review, Flammability Reduction and Maintenance and 
Inspection Requirements'' (66 FR 23086, May 7, 2001). AD 2011-15-02 
also continues to require accomplishing certain fuel system 
modifications, initial inspections of certain repetitive fuel system 
limitations to phase in those inspections, and repair if necessary. AD 
2011-15-02 corrects certain part number references, adds an additional 
inspection area and, for certain airplanes, requires certain actions to 
be re-accomplished according to revised service information. AD 2011-
15-02 was issued to prevent the potential for ignition sources inside 
fuel tanks caused by latent failures, alterations, repairs, or 
maintenance actions, which, in combination with flammable fuel vapors, 
could result in a fuel tank explosion and consequent loss of the 
airplane.
     AD 2012-06-09, Amendment 39-16990 (77 FR 21404, April 10, 
2012), which requires revising the maintenance/inspection program to 
include inspections that will give no less than the required damage 
tolerance analysis for each principal structural element (PSE), doing 
repetitive inspections to detect cracks of all PSEs, and repairing 
cracked structure. We issued this AD to maintain the continued 
structural integrity of the fleet.

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-
09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011). This proposed AD 
would also require replacement of the center wing box, which would 
terminate the repetitive inspections. This proposed AD would add a 
concurrent related investigative action, which involves a bolt hole 
eddy current inspection for cracking at additional fastener locations.
    We revised the phrase ``accomplishment of the service bulletin'' in 
paragraph (g)(3) of AD 2011-09-04, Amendment 39-16666 (76 FR 28626, May 
18, 2011), to specify ``accomplishment of the inspection specified in 
paragraph (g) of this AD.''
    We also have removed Note 1 of AD 2011-09-04, Amendment 39-16666 
(76 FR 28626, May 18, 2011). The text in Note 1 is informational and is 
not a requirement of this proposed AD.

Differences Between This Proposed AD and the Service Information

    Although the service information specifies that operators may 
contact the manufacturer for using adjusted thresholds and intervals, 
using alternative repetitive inspection intervals, and using 
alternative inspection methods, this proposed AD would require 
operators to obtain approval of any alternative thresholds, intervals, 
or inspection methods from the FAA.

Explanation of Compliance Time

    The compliance time for the replacement specified in this proposed 
AD for addressing WFD was established to ensure that discrepant 
structure is replaced before WFD develops in the affected airplanes. 
Standard inspection techniques cannot be relied on to detect WFD before 
it becomes a hazard to flight. We will not grant any extensions of the 
compliance time to complete any AD-mandated service information related 
to WFD without extensive new data that would substantiate and clearly 
warrant such an extension.

Costs of Compliance

    We estimate that this proposed AD affects 15 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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

[[Page 37251]]

safety in air commerce. This proposed 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

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

Revision 1, all dated March 8, 2007. Repeat the inspections 
thereafter at intervals not to exceed 10,000 flight hours. As of the 
effective date of this AD, use only Lockheed Service Bulletin 382-
57-85 (82-790), Revision 3, dated July 8, 2013, including Appendix 
A, dated July 8, 2013, and Appendixes B, C, D, E, F, and G, all 
Revision 1, all dated March 8, 2007, for the actions required by 
this paragraph.
    (1) Prior to the accumulation of 40,000 total flight hours on 
the center wing.
    (2) Within 365 days after June 22, 2011 (the effective date of 
AD 2011-09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011).
    (3) Within 10,000 flight hours on the center wing box after the 
accomplishment of the inspection specified in paragraph (g) of this 
AD, if done before June 22, 2011 (the effective date of AD 2011-09-
04, Amendment 39-16666 (76 FR 28626, May 18, 2011).

(h) Retained Corrective Action With No Changes

    This paragraph restates the actions required by paragraph (h) of 
AD 2011-09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011), with 
no changes. If any damage is found during any inspection required by 
paragraph (g) of this AD: Before further flight, repair any damage, 
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.

(i) Retained Exceptions to Lockheed Service Bulletin 382-57-85 (82-
790), Revision 2, Dated August 23, 2007, Including Appendixes A, B, C, 
D, E, F, and G, All Revision 1, All Dated March 8, 2007, With No 
Changes

    (1) This paragraph restates the exception in paragraph (i) of AD 
2011-09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011), with no 
changes. Lockheed Service Bulletin 382-57-85 (82-790), Revision 2, 
dated August 23, 2007, including Appendixes A, B, C, D, E, F, and G, 
all Revision 1, all dated March 8, 2007, specifies that operators 
may adjust thresholds and intervals, use alternative repetitive 
inspection intervals, and use alternative inspection methods, if 
applicable. However, this AD requires that any alternative methods 
or intervals be approved by the Manager, Atlanta ACO. For any 
alternative methods or intervals to be approved by the Manager, 
Atlanta ACO, as required by this paragraph, the Manager's approval 
letter must specifically refer to this AD.
    (2) This paragraph restates the exception in paragraph (j) of AD 
2011-09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011), with no

Revision 2, dated August 23, 2007, including Appendixes A, B, C, D, 
E, F, and G, all Revision 1, all dated March 8, 2007, specifies that 
alternative repetitive inspection intervals may be used for cold-
worked holes, this AD does not allow the longer interval. This AD 
requires that all cold-worked and non-cold-worked holes be re-
inspected at 10,000-flight-hour intervals.
    (3) This paragraph restates the exception in paragraph (k) of AD 
2011-09-04, Amendment 39-16666 (76 FR 28626, May 18, 2011), with no 
changes. Where Lockheed Service Bulletin 382-57-85 (82-790), 
Revision 2, dated August 23, 2007, including Appendixes A, B, C, D, 
E, F, and G, all Revision 1, all dated March 8, 2007, describes 
procedures for submitting a report of any damages, this AD does not 
require such action.

(j) New Inspection and Corrective Action

    As of the effective date of this AD, concurrently with 
accomplishing the inspection required by paragraph (g) of this AD: 
Do all applicable related investigative actions, in accordance with 
Appendix A of Lockheed Service Bulletin 382-57-85 (82-790), Revision 
3, dated July 8, 2013. If any cracking or damage is found during any 
related investigative action: Before further flight, repair all 
cracking and damage, using 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.

[[Page 37252]]

(k) New Replacement (Terminating Action)

    Before the accumulation of 50,000 total flight hours, or within 
24 months after the effective date of this AD, whichever occurs 
later: Replace the center wing box, in accordance with the 
Accomplishment Instructions of Lockheed Service Bulletin 382-57-94, 
dated December 3, 2013. Accomplishing the replacement terminates the 
inspections required by this AD.

    Note 1 to paragraph (k) of this AD: A note in the Accomplishment 
Instructions of Lockheed Service Bulletin 382-57-94, dated December 
3, 2013, instructs operators to contact Lockheed if any assistance 
is needed in accomplishing the service bulletin. However, any 
deviation from the instructions provided in the service information
