Airworthiness Directives; Lockheed Model 382, 382B, 382E, 382F, 
and 382G Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Lockheed Model 382, 382B, 382E, 382F, and 382G series airplanes. This 
AD 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. This 
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 AD results from a design review of the fuel tank 
systems. 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 November 3, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 3, 
2008.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
all Lockheed Model 382, 382B, 382E, 382F, and 382G series airplanes. 
That NPRM was published in the Federal Register on June 13, 2008 (73 FR 
33740). That NPRM proposed to require revising the FAA-approved 
maintenance program by incorporating new airworthiness limitations for 
fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 
(SFAR 88) requirements. That NPRM also proposed 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.

Actions Since NPRM Was Issued

    Since we issued the NPRM, Lockheed has issued Service Bulletin 382-
28-20, Revision 5, dated June 19, 2008, to reflect changes to the 
required kits. In the NPRM, we referred to Revision 4 of the service 
bulletin, dated May 21, 2007, as an additional source of service 
information for installing ground fault interrupters (GFIs) and flame 
arrestors for protection of the fuel system. The procedures in Revision 
5 of the service bulletin are essentially the same as those in Revision 
4. Therefore, we have revised Table 1 of this AD to refer to Revision 5 
of the service bulletin as the appropriate source of service 
information for installing the GFIs and flame arrestors.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received from the four commenters.

Requests To Revise Compliance Time

    Lynden Air Cargo (LAC) and Safair request that we extend the 
compliance time from 24 months to 36 months for doing the modification 
in paragraph (h) of the NPRM. As justification, the commenters state 
that additional time is needed to procure parts and to accomplish the 
modifications during a heavy maintenance visit.
    We agree to revise the compliance time in paragraph (h) of this AD 
to 36 months. Extending the compliance time will not adversely affect 
safety, and it will allow operators to accomplish the modifications, 
initial inspections, and repairs during regularly scheduled maintenance 
at a base where special equipment and trained maintenance personnel 
will be available if necessary.

Request To Revise Paragraph (g)(1) of the NPRM

    LAC requests that we revise paragraph (g)(1) of the NPRM to refer 
to paragraph 2.C.(3)(e) of Lockheed Service Bulletin 382-28-22, 
Revision 3, dated March 28, 2008, instead of paragraph 2.C.(3)(c). LAC 
believes that ``2.C.(3)(c)'' is a typographical error because all of 
the other critical design configuration control limitation (CDCCL) 
items referred to in paragraph (g)(1) of the NPRM address wiring 
practices and resistance measurements.
    We agree with LAC's request and have revised paragraph (g)(1) of 
this AD accordingly. The CDCCLs referred to 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 Lockheed 
Service Bulletin 382-28-22 are all items that can be accomplished in 
accordance with Lockheed Service Bulletin 382-28-19, Revision 3, dated 
November 30, 2006.

Request To Revise the Method of Compliance in Paragraph (g)(1) of the 
NPRM

    LAC requests that we revise paragraph (g)(1) of the NPRM as 
follows: ``* * * do the applicable actions in accordance with the 
procedures specified in Lockheed Service Bulletin 382-28-19, Revision 
3, dated November 30, 2006, or a method approved in accordance with 
paragraph (k) of this AD.'' Paragraph

[[Page 56465]]

(g)(1) of the NPRM specifies to ``* * * do the applicable actions using 
a method approved in accordance with the procedures specified in 
paragraph (k) of this AD. Lockheed Service Bulletin 382-28-19, Revision 
3, dated November 30, 2006, is one approved method.'' LAC states that 
the language provided in the NPRM could be interpreted to mean that an 
alternative method of compliance (AMOC) is always required.
    We partially agree. We have revised paragraph (g)(1) of this AD to 
specify doing the ``* * * applicable actions in accordance with the 
Accomplishment Instructions of Lockheed Service Bulletin 382-28-19, 
Revision 3, dated November 30, 2006.'' Under the provisions of 
paragraph (k) of this AD, we will consider requests for approval of an 
AMOC, so it is not necessary to restate so in paragraph (g)(1) of this 
AD. We have also deleted the last sentence of paragraph (g)(1) of the 
NPRM, which states ``Lockheed Service Bulletin 382-28-19, Revision 3, 
dated November 30, 2006, is one approved method.'' We would like to 
clarify that the original language in the NPRM would not have required 
operators to always request an AMOC because that last sentence already 
provided one approved method.

Request To Clarify the Intent of Paragraph (i) of the NPRM

    LAC interprets paragraph (i) of the NPRM to mean that the NPRM will 
not be revised to incorporate revised service bulletins. LAC also 
interprets that paragraph to mean that approval of any revised service 
bulletins by the Atlanta Aircraft Certification Office (ACO) 
constitutes approval for including these revised service bulletins into 
its fuel system maintenance program.
    We infer that LAC requests that we confirm whether LAC's 
interpretations are correct. We agree that LAC's interpretations of the 
language in the NPRM are correct. However, we have revised paragraph 
(i) of this AD by removing reference to the use of a ``later revision'' 
of the applicable service information to be consistent with the FAA 
policy and Office of the Federal Register regulations. We might 
consider approving the use of a later revision of the service 
information as an AMOC to this AD, as provided by paragraph (k) of this 
AD.

Request for Clarification of Compliance With Certain Regulations

    LAC asks if compliance with the NPRM constitutes compliance with 
section 121.1113 of the Federal Aviation Regulations (14 CFR 121.1113). 
If so, LAC requests that the AD state so. LAC cites 14 CFR 121.1113(f), 
which states ``* * * any later fuel tank system revisions must be 
submitted to the Principal Inspector for review and approval.'' LAC 
interprets this regulation to mean that, even after the Atlanta ACO has 
approved a revised service bulletin, LAC would still be required to 
obtain approval from the principal inspector to incorporate the revised 
service bulletin into its fuel system maintenance program.
    LAC also points out that the preamble of the NPRM states that the 
NPRM would also allow accomplishing the maintenance program revision in 
accordance with later revisions of Lockheed Service Bulletin 382-28-22 
as an acceptable method of compliance if they are approved by the 
Manager, Atlanta ACO. LAC interprets the phrase ``would also allow'' to 
mean that LAC has the option, after ACO approval, to incorporate the 
revised service bulletin into its maintenance program, and that it 
would neither be mandatory, nor could a principal inspector require the 
incorporation of the revised service bulletin unless this AD was 
superseded to mandate the revised service bulletin.
    Yes, we agree that even after ACO approval of a later revision of 
the service bulletin, an operator would still be required to obtain 
approval from the principal inspector before a later FAA-approved 
service bulletin could be incorporated into its maintenance program. 
Further, as stated previously, we have removed the reference for using 
later revisions of the service bulletin approved by the Atlanta ACO. 
Operators may request approval for the use of later revisions of the 
service information as an AMOC to this AD, as provided by paragraph (k) 
of this AD. No change to the AD is necessary in this regard.

Request To Revise Applicability

    A commenter, William L. Davis, states that we might have 
inadvertently omitted certain U.S.-registered Model C-130 airplanes 
from the applicability of the NPRM. The commenter refers us to Type 
Certificate Data Sheets A15NM, A30NM, A31NM, A33NM, A34SO, A39CE, A5SO, 
and TQ3CH. The commenter asks if we intentionally excluded these 
airplanes from the NPRM.
    Yes, we have intentionally excluded the airplanes that the 
commenter refers to because they are restricted category airplanes, 
which are not affected by this AD. This AD applies only to Model 382, 
382B, 382E, 382F, and 382G series airplanes, which are transport 
category airplanes. We have not changed the AD in this regard.

Request To Reduce the Estimated Number of Affected Airplanes

    Lockheed states that its data show that the number of U.S.-
registered airplanes that would be affected by the NPRM is 14.
    We infer Lockheed requests that we reduce the estimated number of 
affected airplanes from 21 to 14 in the Costs of Compliance section of 
this AD. We disagree because we have researched this issue and 
determined that this AD applies to 24 U.S.-registered airplanes. Of 
these airplanes, 14 are active and 10 are inactive. The inactive 
airplanes need to be included in our estimate to provide for any 
airplanes that might return to service in the future. Therefore, we 
have revised our estimate in this AD to 24 airplanes, and we have 
updated the Estimated Costs table of this AD accordingly.

Request To Revise the Compliance Time in Paragraph (g) of the NPRM

    LAC requests that we revise the compliance date in paragraph (g) of 
the AD from December 16, 2008, to December 17, 2008. LAC points out 
that, in the Explanation of Compliance Time section of the NPRM, we 
specified that the compliance date is December 16, 2008, for 
regulations addressing fuel tank safety issues. However, LAC asserts 
that the actual date that operators must be in compliance with this AD 
is December 17, 2008. As justification, LAC cites section 14 CFR 
121.1113(c), which states: ``After December 16, 2008, no certificate 
holder may operate an airplane * * * unless the maintenance program for 
that airplane has been revised to include applicable inspections, 
procedures, and limitations for fuel tanks systems.''
    We disagree with changing the compliance date. ``After December 16, 
2008'' means that operators must revise their maintenance programs to 
address fuel tank systems on or before December 16, 2008, in order to 
be in compliance after December 16, 2008. Therefore, the compliance 
date is December 16, 2008. We have not changed the AD in this regard.

Request To Revise the Compliance Time in Paragraph (h) of the NPRM

    Lockheed points out that the compliance time in paragraph (h) of 
the NPRM appears to conflict with the compliance date of December 16, 
2008, for complying with SFAR 88 regulations, as specified in the 
Explanation of Compliance Time section and in paragraph (g) of the 
NPRM.
    We infer Lockheed requests that we revise the compliance time in 
paragraph

[[Page 56466]]

(h) of this AD to December 16, 2008. We disagree because 14 CFR 
121.1113(c) requires only that operators revise their maintenance 
programs to include applicable inspections, procedures, and limitations 
for fuel tank systems on or before December 16, 2008. Further, to avoid 
unduly burdening operators, it is necessary to provide a 36-month grace 
period for accomplishing the modifications, initial inspections, and 
repairs specified in paragraph (h) of this AD. We have not changed the 
AD in this regard.

Request To Revise the Wire Separation Requirement

    LAC requests that paragraph 2.C.(8)(a)2a of Lockheed Service 
Bulletin 382-28-19, Revision 3, dated November 30, 2006, be revised to 
specify that ``* * * between FS 245.0 and FS 597.0 (along the wing 
trailing edge) where wires pass through cutouts in the structure, \1/2\ 
to 2 inches in separation is permitted between wire bundles.'' The 
service bulletin currently states this separation allowance is between 
fuselage station (FS) 245.0 and FS 457.0. However, LAC states the ``FS 
457.0'' appears to be an error because the wing trailing edge is at FS 
597.0.
    We disagree that FS 457.0 should be revised to FS 597.0. We have 
verified with the Lockheed that FS 457.0 is the correct location. This 
fuselage station corresponds to the wing root area, which is outside of 
the pressure vessel and where the wires pass along the wing trailing 
edge. Lockheed intends to revise the service bulletin to clarify the 
wire separation requirement and provide additional information. No 
change to the AD is necessary in this regard.

Request To Provide Installation Instructions for the GFIs and Flame 
Arrestors

    LAC states that Lockheed Service Bulletin 382-28-20, Revision 4, 
dated May 21, 2007, is an informational and planning service bulletin. 
LAC also states that the service bulletin does not contain any 
instructions for installing the GFIs and flame arrestors, and that it 
instead refers to Installation Kit Drawing 3359620 for those 
instructions. LAC states that it cannot comment without being able to 
see the drawing and requests that the drawing is made available. Also, 
LAC asks what approved data is used for the installation of the kits 
and who approved it.
    We acknowledge LAC's comments. The FAA approved the data for the 
installation kits through design analysis and testing. The installation 
was then conformed and tested on a Model 382 series airplane. We have 
coordinated with Lockheed and it has stated that the installation 
drawings were made available to LAC the first week of August 2008. 
Also, Lockheed has stated that it intends to include that information 
directly in a future revision of Lockheed Service Bulletin 382-28-20. 
If the service bulletin is revised after issuance of this AD, we may 
consider approving the use of a later revision of the service 
information as an AMOC with this AD, as provided by paragraph (k) of 
this AD. No change to the AD is necessary in this regard.

Request To Standardize Approval Statements

    LAC requests that we use the following FAA approval statement in 
service bulletins: ``Approved by FAA Atlanta Certification Office.'' 
LAC states that the approval statements are either inconsistent or non-
existent for the service bulletins referenced in the NPRM.
    We acknowledge LAC's request. However, this request is best 
presented to the airplane manufacturer, who develops and includes the 
applicable approval statement in the service bulletin. No change to the 
AD is necessary in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We also determined that 
these changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 24 airplanes of U.S. registry. The 
following table provides the estimated costs, at an average labor rate 
of $80 per hour, for U.S. operators 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

[[Page 56467]]

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), 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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-20-01 Lockheed: Amendment 39-15680. Docket No. FAA-2008-0638; 
Directorate Identifier 2008-NM-035-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective November 3, 
2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Lockheed Model 382, 382B, 382E, 382F, 
and 382G series 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 (k) 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.

Unsafe Condition

    (d) This AD results from a design review of the fuel tank 
systems. 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.

Compliance

    (e) Comply with this AD within the compliance times specified, 
unless already done.

Service Bulletin Reference

    (f) The term ``service bulletin,'' as used in this AD, means the 
Accomplishment Instructions of Lockheed Service Bulletin 382-28-22, 
Revision 3, dated March 28, 2008.

Maintenance Program Revision

    (g) Before December 16, 2008, revise the FAA-approved 
maintenance program to incorporate the fuel system limitations 
(FSLs) and the critical design configuration control limitations 
(CDCCLs) specified in the Accomplishment Instructions of the service 
bulletin; 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 
service bulletin, do the applicable actions in accordance with the 
Accomplishment Instructions of Lockheed Service Bulletin 382-28-19, 
Revision 3, dated November 30, 2006.
    (2) Where paragraph 2.C.(1)(c) of the service bulletin 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.
    (3) Where the service bulletin 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 the effective date of this AD, do the 
applicable actions specified in Table 1 of this AD, and repair any 
discrepancy before further flight, in accordance with the service 
bulletin.
