Airworthiness Directives; Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Model 382, 382B, 382E, 382F, and 382G airplanes. That AD 
currently requires revising the FAA-approved maintenance program by 
incorporating new airworthiness limitations for fuel tank systems to 
satisfy Special Federal Aviation Regulation No. 88 requirements. That 
AD also requires the accomplishment of certain fuel system 
modifications, the initial inspections of certain repetitive fuel 
system limitations to phase in those inspections, and repair if 
necessary. This new AD 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. 
This AD was prompted by a report of incorrect accomplishment 
information in the service information cited by the existing AD. We are 
issuing this AD 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.

DATES: This AD is effective August 19, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 19, 
2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
November 3, 2008 (73 FR 56464, dated September 29, 2008).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede airworthiness directive (AD) 2008-20-01, amendment 
39-15680 (73 FR 56464, September 29, 2008). That AD applies to the 
specified products. The NPRM published in the Federal Register on 
January 5, 2011 (76 FR 485). That NPRM proposed to continue to require 
revising the maintenance program by incorporating new airworthiness 
limitations for fuel tank systems to satisfy Special Federal Aviation 
Regulation No. 88 requirements. That NPRM also proposed to continue to 
require the accomplishment of certain fuel system modifications, the 
initial inspections of certain repetitive fuel system limitations to 
phase in those inspections, and repair if necessary. That NPRM also 
proposed to correct certain part number references, add an additional 
inspection area, and for certain airplanes, require certain actions to 
be re-accomplished according to revised service information.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to the comment.

Request To Revise Cost Estimate

    Lynden Air Cargo requested that the cost for revising the 
Instructions for Continued Airworthiness be included in the Costs of 
Compliance estimate. Lynden Air Cargo stated that there is a 
significant amount of work-hours associated with revising ``company 
manuals, job cards, maintenance programs, computerized tracking 
programs and record keeping documents'' so that the operator can comply 
with the requirements of a new AD. Lynden Air Cargo estimated that 
these actions will take at least 80 work-hours for its office staff, 
and estimated that this cost would affect other operators. Lynden Air 
Cargo also pointed out that this work load for the office staff will 
have a greater impact on smaller fleet operators with smaller staff.
    We agree that a requirement of the new AD will require an update of 
the maintenance program to incorporate references to revised service 
information. This action is estimated to take approximately 1 work-hour 
per airplane. However, we disagree with increasing the estimated work-
hours for the time that it takes for writing job cards, tracking 
programs, or record-keeping, since those actions are not directly 
required by this AD. The costs specified by Lynden Air Cargo will not 
be the same for all operators. The Costs of Compliance estimate has 
been revised accordingly.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Costs of Compliance

    There are about 62 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD. The average labor rate per hour 
is $85. The costs of the new requirements of this AD are as follows:

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 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.

List of Subjects in 14 CFR Part 39

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

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 removing airworthiness directive (AD) 
2008-20-01, Amendment 39-15680 (73 FR 56464, September 29, 2008), and 
adding the following new AD:

2011-15-02 Lockheed Martin Corporation/Lockheed Martin Aeronautics 
Company: Amendment 39-16749; Docket No. FAA-2010-1305; Directorate 
Identifier 2010-NM-074-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective August 19, 
2011.

Affected ADs

    (b) This AD supersedes AD 2008-20-01, Amendment 39-15680.

Applicability

    (c) This AD applies to all Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G 
airplanes, certificated in any category.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include new inspections. Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by these inspections, the operator may not be able 
to accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (o) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued operational safety of the airplane.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Unsafe Condition

    (e) This AD results from a design review of the fuel tank 
systems. The Federal Aviation Administration is issuing this AD 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.

Compliance

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

RESTATEMENT OF REQUIREMENTS OF AD 2008-20-01, WITH NEW SERVICE 
INFORMATION:
