Airworthiness Directives; Lockheed Model L-1011 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Lockheed Model L-1011 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 June 25, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 25, 
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 L-1011 series airplanes. That NPRM was published in 
the Federal Register on February 20, 2008 (73 FR 9235). That NPRM 
proposed to require revising the FAA-approved maintenance program by 
incorporating new airworthiness limitations (AWLs) 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 (FSLs) to 
phase in those inspections, and repair if necessary.

Comments

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

Request To Supersede AD 2001-08-21, Amendment 39-12198

    ATA Airlines requests that we revise the NPRM by removing the 
proposed requirement to accomplish the FSL specified in paragraph 
2.B.(1)(d) of Lockheed Service Bulletin 093-28-098, Revision 1, dated 
January 22, 2008. (Lockheed Service Bulletin 093-28-098, Revision 1, 
refers to Lockheed Service Bulletin 093-28-094, Revision 1, dated June 
23, 2006, for accomplishing that FSL.) The commenter further requests 
that we instead issue a separate rulemaking action to supersede AD 
2001-08-21 (66 FR 21072, April 27, 2001) to require the accomplishment 
of Revision 1 of Lockheed Service Bulletin 093-28-094. (As stated in 
the NPRM, AD 2001-08-21 requires the accomplishment of the original 
issue of Lockheed Service Bulletin 093-28-094, dated March 3, 2000, but 
more work is necessary for Revision 1 of the service bulletin.)
    We agree that it is more appropriate to require the accomplishment 
of Revision 1 of Lockheed Service Bulletin 093-28-094 by superseding AD 
2001-08-21. Our current policy specifies that, whenever a ``substantive 
change'' is made to an existing AD that imposes a new burden, we must 
supersede the AD. ``Substantive changes'' are those made to any 
instruction or reference that affects the substance of the AD. 
Substantive changes include part numbers, service bulletin and manual 
references, compliance times, applicability, methods of compliance, 
corrective action, inspection requirements, and effective dates. We 
consider the changes in Revision 1 of the service bulletin to be 
substantive. Therefore, we have revised paragraphs (h) and (i) and 
Table 2 of this AD by removing references to paragraph 2.B.(1)(d) and 
Lockheed Service Bulletin 093-28-094. Further, we will consider 
superseding AD 2001-08-21 with a separate rulemaking action.

Request To Extend the Compliance Time for Certain Actions

    ATA Airlines requests that we extend the compliance time for 
accomplishing the FSLs in paragraphs 2.B.(1)(d), 2.B.(1)(e), 
2.B.(1)(f), and 2.B.(1)(g) of Lockheed Service Bulletin 093-28-098, 
Revision 1, dated January 22, 2008, to the following: on or before the 
next heavy maintenance inspection after the effective date of the AD, 
but not to exceed 60 months after the effective date of the AD. The 
commenter recommends revising the compliance time by either adding a 
compliance time, initial threshold, and grace period

[[Page 29411]]

to Table 2 of the NPRM, or removing Table 2 from the NPRM and issuing 
separate rulemaking actions to address those FSLs. The commenter also 
requests that we include a note in the AD to define a heavy maintenance 
inspection as equivalent to a ``D'' check and similar to the definition 
in the Lockheed L-1011 Maintenance Review Board Report, dated March 1, 
1998.
    As justification for its request, the commenter states that the 
NPRM is inconsistent with other rulemaking actions addressing other 
airplane models. The commenter also states that those other rulemaking 
actions are consistent with the guidance in FAA Policy Memorandum PS-
ANM112-05-001, ``Policy Statement on Process for Developing SFAR 88-
Related Instructions for Maintenance and Inspection of Fuel Tank 
Systems,'' dated October 6, 2004. In support of its position, the 
commenter refers to paragraphs 3.D, 3.D.1, and 4 of that policy 
memorandum, and to the ``Four-Element Unsafe Condition Evaluation 
Criteria'' section of FAA Policy Memorandum PS-ANM100-2003-112-15, 
``SFAR 88--Mandatory Action Design Criteria,'' dated February 25, 2003. 
The commenter contends that each identified unsafe condition and the 
AWL changes should be issued as separate rulemaking actions.
    The commenter also contends that it would be unduly and 
disproportionately impacted by the proposed requirements of the NPRM. 
The commenter states that, for other airplane models, we have issued 
separate rulemaking actions to address design changes and the 
incorporation of AWLs for fuel tank systems into the FAA-approved 
maintenance program. The commenter also states that, in some instances, 
we have provided a compliance time of up to 5 years for accomplishing 
the design changes. The commenter, therefore, asserts that requiring 
the accomplishment of the design changes identified in Table 2 of the 
NPRM by December 16, 2008, is a substantial, immediate burden.
    The commenter also asserts that paragraph (h) of the NPRM 
effectively makes the service bulletins identified in Table 2 of the 
NPRM retroactively applicable. The commenter notes that Table 2 does 
not include the compliance times recommended in those service 
bulletins. ATA Airlines believes that, as written, the NPRM would 
effectively make the compliance recommendation of up to 2-year-old 
service documents rule. As an example, the commenter points to Lockheed 
Service Bulletin 093-28-096, dated June 8, 2004, which recommends doing 
the initial inspection of the wiring harnesses of the No. 1 and No. 3 
engine tank valves on or before the next heavy maintenance inspection, 
but not to exceed 5 years from the date of the service bulletin. That 
service bulletin also recommends revising the maintenance planning 
documentation to require repeating the inspection at intervals not to 
exceed 10 years from the date of the last inspection. The commenter 
states that, upon issuance of the final rule, an operator is at risk of 
non-compliance, since it is possible for an airplane to have undergone 
a heavy maintenance inspection between publication of the service 
bulletin and the effective date of the AD without having accomplished 
the actions specified in the service bulletin.
    We agree to extend the compliance time for accomplishing the design 
changes identified in paragraphs 2.B.(1)(d), 2.B.(1)(e), 2.B.(1)(f), 
and 2.B.(1)(g) of Lockheed Service Bulletin 093-28-098, Revision 1. We 
have added a new paragraph (h)(2) specifying that the FSLs in 
paragraphs 2.B.(1)(e), 2.B.(1)(f), and 2.B.(1)(g) must be done within 
60 months after the effective date of this AD. As stated previously, we 
have removed the requirement to accomplish the FSL in paragraph 
2.B.(1)(d) of Lockheed Service Bulletin 093-28-098, Revision 1.
    However, we disagree with issuing separate ADs to address the other 
design changes identified in Table 2 of this AD. The policy memorandum 
to which the commenter refers to does not specify that the design 
changes must be addressed by separate rulemaking actions. We also point 
out that when the compliance time in an AD differs from the recommended 
compliance time in a service bulletin, operators are required to comply 
with the compliance time specified in the AD, not the service bulletin. 
We have not changed this AD in this regard.

Request To Extend the Compliance Time of Paragraph (g)

    ATA Airlines requests that we extend the compliance time by 1 year 
to December 16, 2009 in paragraph (g) of the NPRM. The commenter states 
that the airplane manufacturers of other airplane models have provided 
comprehensive data to support operators in complying with a compliance 
date of December 16, 2008. As an example, the commenter refers to 
Docket Nos. FAA-2006-26710, FAA-2007-28383, and FAA-2007-28384 
published on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>. The commenter 
states that those NPRMs all refer to comprehensive maintenance planning 
documents provided by the airplane manufacturer, and that those NPRMs 
provide explicit thresholds and grace periods for accomplishing many of 
the AWLs for fuel tank systems. The commenter also states that the 
airplane manufacturer either has or is providing comprehensive 
revisions to the AWLs section of the Instructions for Continued 
Airworthiness (ICA) to address critical design configuration control 
limitations (CDCCLs) and other SFAR 88 findings. The commenter asserts 
that Lockheed has not provided the same level of support, which 
substantially increases the burden on operators. The commenter believes 
that, as a result of the manner and timeliness of the data provided for 
the Model L-1011 series airplanes, it is appropriate and justifiable to 
provide a 12-month grace period for operators to amend their 
maintenance programs.
    We disagree with extending the compliance time for paragraph (g) of 
this AD. We have determined that Lockheed has met the minimum 
requirements for supporting operators in complying with the SFAR 88 
requirements. Further, in other similar NPRMs for other airplane 
models, we have not provided a grace period for revising the FAA-
approved maintenance program or the AWLs section of ICA, as applicable, 
to incorporate AWLs for fuel tank systems. As stated in the preambles 
of those NPRMs, we have already issued regulations that require 
operators to revise their maintenance/inspection programs to address 
fuel tank safety issues. The compliance date for these regulations is 
December 16, 2008. To provide for efficient and coordinated 
implementation of these regulations and those NPRMs, we are using this 
same compliance date. We have not changed this AD in this regard.

Request To Extend the Comment Period

    ATA Airlines requests that we extend the comment period for a 
minimum of 30 days. As justification, the commenter states that 
Lockheed Service Bulletin 093-28-098, Revision 1, dated January 22, 
2008, was not available to operators until 9 days after the NPRM was 
published in the Federal Register.
    We disagree with extending the comment period. We have attempted to 
contact this commenter to better understand its needs and rationale 
with regard to extending the comment period. However, we have been 
unable to reach the commenter after numerous attempts. To further delay 
this action would be inappropriate, since we have determined that an 
unsafe condition exists and it must be addressed to ensure continued 
safety.

[[Page 29412]]

Request To Revise Paragraph (b)

    ATA Airlines notes that paragraph (b) of the NPRM specifies that no 
other airworthiness directives are affected by the NPRM. The commenter 
believes that this is incorrect because Lockheed Service Bulletin 093-
28-098, Revision 1, dated January 22, 2008, refers to AD 80-25-04, 
amendment 39-3983 (45 FR 79011, November 28, 1980); AD 99-24-12, 
amendment 39-11436 (64 FR 66756, November 30, 1999); and AD 2001-08-21. 
(AD 80-25-04 requires accomplishing the actions specified in Lockheed 
Service Bulletin 093-28-062, Revision 1, dated August 20, 1980. AD 99-
24-12 requires accomplishing the actions specified in Lockheed Service 
Bulletin 093-28-093, Revision 1, dated February 8, 1999. AD 2001-08-21 
requires accomplishing the actions specified in Lockheed Service 
Bulletin 093-28-094, dated March 3, 2000.) The commenter states that AD 
2001-08-21 should be identified as a superseded AD, according to 
paragraph 121.b. of Section 12 of the ``Airworthiness Directives 
Manual,'' FAA-IR-M-8040.1A.
    We infer the commenter requests that we revise paragraph (b) of 
this AD to specify that this AD is related to AD 80-25-04 and AD 99-24-
12, and that it supersedes AD 2001-08-21. We disagree with revising 
paragraph (b) of this AD. Paragraph (b) of an AD is reserved for 
referencing any previously issued AD that is revised or superseded by a 
new AD. As stated previously, we will consider superseding AD 2001-08-
21 with a separate rulemaking action. No change to this AD is necessary 
in this regard.

Change Made to This AD

    We have revised paragraph (g) of this AD to require revising the 
FAA-approved maintenance program to incorporate the FSLs and CDCCLs 
specified in Lockheed Service Bulletin 093-28-098, Revision 1, except 
as provided by paragraphs (g)(1), (g)(2), and (h) of this AD. In the 
NPRM, we inadvertently omitted reference to paragraph (h).

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

    There are about 108 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs, at 
an average labor rate of $80 per work 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 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

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

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

[[Page 29413]]

Sec.  39.13  [Amended]

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

2008-11-02 Lockheed: Amendment 39-15524. Docket No. FAA-2008-0181; 
Directorate Identifier 2007-NM-180-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective June 25, 
2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Lockheed Model L-1011 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 (AMOC) in 
accordance with 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) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Service Bulletin Reference

    (f) The term ``service bulletin,'' as used in this AD, means the 
Accomplishment Instructions of Lockheed Service Bulletin 093-28-098, 
Revision 1, dated January 22, 2008.

Maintenance Program Revision

    (g) Before December 16, 2008, revise the FAA-approved 
maintenance program to incorporate the fuel system limitations 
(FSLs) specified in paragraphs 2.B.(1)(b), 2.B.(1)(e), 2.B.(1)(f), 
and 2.B.(1)(g) of the service bulletin, and the critical design 
configuration control limitations (CDCCLs) specified in paragraph 
2.C. of the service bulletin; except as provided by paragraphs 
(g)(1), (g)(2), and (h) of this AD.
    (1) Where the FSLs specify to inspect, this AD would require 
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.''

    (2) For the CDCCLs specified in paragraphs 2.C.(2)(c), 
2.C.(2)(d), and 2.C.(15)(a) of the service bulletin, do the 
applicable actions using a method approved in accordance with the 
procedures specified in paragraph (k) of this AD. The applicable 
service information listed in Table 1 of this AD is one approved 
method.
