ACTION: Final rule. jlentini on PROD1PC65 with RULES AGENCY: 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: Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the four commenters. 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. 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. 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 PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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 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 E:\FR\FM\29SER1.SGM 29SER1 Federal Register / Vol. 73, No. 189 / Monday, September 29, 2008 / Rules and Regulations (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. jlentini on PROD1PC65 with RULES 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 VerDate Aug<31>2005 16:29 Sep 26, 2008 Jkt 214001 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 FAAapproved 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. PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 56465 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 E:\FR\FM\29SER1.SGM 29SER1 56466 Federal Register / Vol. 73, No. 189 / Monday, September 29, 2008 / Rules and Regulations (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. 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 Provide Installation Instructions for the GFIs and Flame Arrestors Request To Standardize Approval Statements 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 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.

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: ■ 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. [Amended] 2. The FAA amends § 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. 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. ■ § 39.13 Affected ADs (b) None. 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 56467 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.

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.

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.
