14 CFR Part 39

[Docket No. FAA-2010-1305; Directorate Identifier 2010-NM-074-AD]
RIN 2120-AA64


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

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to all Model 382, 382B, 382E, 382F, and 
382G airplanes. The existing 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 proposed AD would 
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. This proposed AD 
results from a report of incorrect accomplishment information in the 
service information cited by the existing AD. We are proposing 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: We must receive comments on this proposed AD by February 22, 
2011.

Discussion

    The FAA has examined the underlying safety issues involved in fuel 
tank explosions on several large transport airplanes, including the 
adequacy of existing regulations, the service history of airplanes 
subject to those regulations, and existing maintenance practices for 
fuel tank systems. As a result of those findings, we issued a 
regulation titled ``Transport Airplane Fuel Tank System Design Review, 
Flammability Reduction and Maintenance and Inspection Requirements'' 
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards 
for transport airplanes and new maintenance requirements, this rule 
included Special Federal Aviation Regulation No. 88 (``SFAR 88,'' 
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e., 
type certificate (TC) and supplemental type certificate (STC)) holders 
to substantiate that their fuel tank systems can prevent ignition 
sources in the fuel tanks. This requirement applies to type design 
holders for large turbine-powered transport airplanes and for 
subsequent modifications to those airplanes. It requires them to 
perform design reviews and to develop design changes and maintenance 
procedures if their designs do not meet the new fuel tank safety 
standards. As explained in the preamble to the rule, we intended to 
adopt airworthiness directives to mandate any changes found necessary 
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four 
criteria intended to define the unsafe conditions associated with fuel 
tank systems that require corrective actions. The percentage of 
operating time during which fuel tanks are exposed to flammable 
conditions is one of these criteria. The other three criteria address 
the failure types under evaluation: single failures, single failures in 
combination with a latent condition(s), and in-service failure 
experience. For all four criteria, the evaluations included 
consideration of previous actions taken that may mitigate the need for 
further action.
    We have determined that the actions identified in this AD are 
necessary to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.
    On September 11, 2008, we issued AD 2008-20-01, amendment 39-15680 
(73 FR 56464, September 29, 2008), for all Model 382, 382B, 382E, 382F, 
and 382G airplanes. That AD requires revising the 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. That AD resulted from a design review of the fuel tank 
systems. We issued that 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.

Actions Since Existing AD Was Issued

    Since we issued AD 2008-20-01, we received information from the 
manufacturer that Lockheed Service Bulletin 382-28-21, Revision 2, 
dated November 20, 2006 (referenced in AD 2008-20-01 as a source of 
additional guidance), contained an error in referencing certain part 
numbers for tube, fuel tank, and bulkhead joint jumpers. The part 
numbers as referenced in Revision 2 of that service bulletin do not 
exist. The manufacturer has published Lockheed Service Bulletin 382-28-
21, Revision 4, dated January 6, 2010, to provide the correct part 
number references. We have revised Table 1 of this AD accordingly.
    We have also received information from the manufacturer that the 
last two bulleted steps of paragraphs 2.C.(2)(b)5 and 2.C.(2)(c)3 of 
Lockheed Service Bulletin 382-28-22, Revision 3, dated March 28, 2008, 
contain an error. Those steps specify that the GFI FAILURE and GROUND 
FAULT DETECTED lights illuminate for 2 seconds. An alternate means of 
compliance (AMOC) for AD 2008-20-01 was issued to disregard those 
steps. The manufacturer has advised that it is planning to publish a 
revision to Lockheed Service Bulletin 382-28-22, Revision 3, dated 
March 28, 2008. However, we have determined that delaying this action 
until after the release of this planned revision is not warranted, 
since sufficient notice of the error in Lockheed Service Bulletin 382-
28-22, Revision 3, dated March 28, 2008, exists.

Relevant Service Information

    We have also reviewed Lockheed Service Bulletin 382-28-19, Revision 
4, dated September 18, 2008. That service bulletin describes procedures 
that are similar to those in Lockheed Service Bulletin 382-28-19, 
Revision 3, dated November 30, 2006 (which was referenced in AD 2008-
20-01 as a source of additional guidance). However, Revision 4 of 
Lockheed Service Bulletin 382-28-19 specifies an additional inspection 
area (fuel probes) for the dry bay and other areas and revises actions. 
Revision 4 of that service bulletin also specifies that for airplanes 
on which the actions described in Revision 3 of Lockheed Service 
Bulletin 382-28-19 are done, it is necessary to do the additional 
action of inspecting the fuel probes when doing the zonal inspection of 
the dry bay areas and other areas and re-accomplish certain inspections 
of certain fuel system electrical wires (such as ensuring that 
generator wire bundles are separated from fuel tank boundaries, certain 
wire bundles are spot tied with certain lacing braid, and that the fuel 
quantity indication system (FQIS) wiring in certain locations is routed 
separately from AC power wires and is shielded using the correct 
standard).
    We have also reviewed Lockheed Service Bulletin 382-28-20, Revision 
11, dated April 20, 2010. That service bulletin describes procedures 
that are similar to Lockheed Service Bulletin 382-28-20, Revision 5, 
dated June 19, 2008 (which was referenced as a source of guidance in AD 
2008-20-01), for installing ground fault interrupters (GFIs) and flame 
arrestors for protection of the fuel system.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to develop on other airplanes of the 
same type design. For this reason, we are proposing this AD, which 
would supersede AD 2008-20-01 and would retain the requirements of the 
existing AD. This

[[Page 487]]

proposed AD would also require certain actions to be re-accomplished 
according to revised service information described previously, except 
as discussed under ``Difference Between the Proposed AD and the Service 
Information.''

Difference Between the Proposed AD and the Service Information

    Although Lockheed Service Bulletin 382-28-19, Revision 4, dated 
September 18, 2008, describes procedures for notifying Lockheed of any 
discrepancies found during inspection, this proposed AD would not 
require that action.

Explanation of Change to This AD

    We have removed the ``Service Bulletin Reference'' paragraph from 
this NPRM. That paragraph was identified as paragraph (f) in AD 2008-
20-01. Instead, we have provided the full service bulletin citations 
throughout this NPRM.

Explanation of Change to Applicability

    We have revised the NPRM to identify the legal name of the 
manufacturer as published in the most recent type certificate data 
sheet for the affected airplane models.

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 proposed AD. The average labor rate 
per hour is $85. The costs of the new requirements of this proposed 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 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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

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:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by removing amendment 39-15680 (73 FR 
56464, September 29, 2008) and adding the following new AD:

Lockheed Martin Corporation/Lockheed Martin Aeronautics Company: 
Docket No. FAA-2010-1305; Directorate Identifier 2010-NM-074-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by February 
22, 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

Maintenance Program Revision

    (g) Before December 16, 2008, revise the maintenance program to 
incorporate the fuel system limitations (FSLs) and the critical 
design configuration control limitations (CDCCLs) specified in the 
Accomplishment Instructions of the Lockheed Service Bulletin 382-28-
22, Revision 3, dated March 28, 2008; except as provided by 
paragraphs (g)(1), (g)(2), and (g)(3) of this AD, and except that 
the modifications and initial inspections specified in Table 1 of 
this AD must be done at the compliance time specified in paragraph 
(h) of this AD.
    (1) For the CDCCLs specified in paragraphs 2.C.(3)(e), 
2.C.(3)(h), 2.C.(4)(a), 2.C.(5)(c), 2.C.(7)(h), and 2.C.(8) of the 
Accomplishment Instructions of Lockheed Service Bulletin 382-28-22, 
Revision 3, dated March 28, 2008, do the applicable actions in 
accordance with the Accomplishment Instructions of Lockheed Service 
Bulletin 382-28-19, Revision 3, dated November 30, 2006; or Revision 
4, dated September 18, 2008. After the effective date of this AD, 
use only Revision 4.
    (2) Where paragraph 2.C.(1)(c) of the Accomplishment 
Instructions of Lockheed Service Bulletin 382-28-22, Revision 3, 
dated March 28, 2008, specifies to change the maintenance program to 
indicate that repetitive inspections of the lightning and static 
bonding jumpers must be done in accordance with Lockheed Service 
Bulletin 382-28-21, instead do the repetitive inspections in 
accordance with Lockheed Service Bulletin 382-28-19, Revision 3, 
dated November 30, 2006; or Revision 4, dated September 18, 2008. 
After the effective date of this AD, use only Revision 4.
    (3) Where Lockheed Service Bulletin 382-28-22, Revision 3, dated 
March 28, 2008, specifies to inspect, this AD requires doing a 
general visual inspection.

    Note 2: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

Fuel System Modifications, Initial Inspections, and Repair If Necessary

    (h) Within 36 months after November 3, 2008 (the effective date 
of AD 2008-20-01), do the applicable actions specified in Table 1 of 
this AD, and repair any discrepancy before further flight, in 
accordance with the Accomplishment Instructions of Lockheed Service 
Bulletin 382-28-22, Revision 3, dated March 28, 2008.
