Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes

Publication summary

We are superseding an existing airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 airplanes. That AD currently requires implementation of a Supplemental Inspection Document (SID) program of structural inspections to detect fatigue cracking, and repair if necessary, to ensure continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. This new AD adds Model L-1011-385-3 airplanes to the applicability, changes certain inspection thresholds, adds three new structurally significant details (SSDs), and removes an SSD that has been addressed by a different AD. This AD was prompted by an evaluation by the manufacturer of usage and flight data that provided additional information about certain SSDs where fatigue damage is likely to occur. We are issuing this AD to prevent fatigue cracking that could compromise the structural integrity of these airplanes.

Retained Maintenance Program Revision
(g) Retained Maintenance Program Revision

    This maintenance program revision is retained from AD 95-20-04 
R1, Amendment 39-9454 (60 FR 63414, December 11, 1995): For Model L-
1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 airplanes: Within 
12 months after November 2, 1995 (the effective date of AD 95-20-04 
R1, Amendment 39-9454 (60 FR 63414, December 11, 1995)), incorporate 
a revision into the maintenance inspection program which provides 
for inspection(s) of the structurally significant details (SSD) 
defined in Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994. Doing the 
revision required by paragraph (h) of this AD terminates the 
requirement to revise the maintenance inspections program specified 
in this paragraph. Doing the inspections required by paragraph (i) 
of this AD terminates the corresponding inspection requirements of 
this paragraph.
    (1) The initial inspection for each SSD must be performed at the 
later of the times specified in paragraph (g)(1)(i) or (g)(1)(ii) of 
this AD.
    (i) Within one repeat interval measured from November 2, 1996 
(12 months after November 2, 1995).
    (ii) Prior to the threshold specified in Lockheed Document 
Number LG92ER0060, ``L-1011-385 Series Supplemental Inspection 
Document,'' revised January 1994, for that SSD.
    (2) A 10 percent deviation from the repetitive interval 
specified in Lockheed Document Number LG92ER0060, ``L-1011-385 
Series Supplemental Inspection Document,'' revised January 1994, for 
that SSD is acceptable to allow for planning and scheduling time.
    (3) If Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994, specifies 
that inspection of any SSD be performed at every ``C'' check, those 
inspections must be performed at intervals not to exceed 5,000 hours 
time-in-service or 2,500 flight cycles, whichever occurs earlier.
    (4) If Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994, specifies 
either the initial inspection or the repetitive inspection intervals 
for any SSD in terms of flight hours or flight cycles, the 
inspection shall be performed prior to the earlier of the terms 
(whichever occurs first on the airplane: either accumulated number 
of flight hours, or accumulated number of flight cycles).
    (5) The non-destructive inspection techniques referenced in 
Section VI., ``Appendix,'' of Lockheed Document Number LG92ER0060, 
``L-1011-385 Series Supplemental Inspection Document,'' revised 
January 1994, provide acceptable methods for accomplishing the 
inspections required by paragraph (g) of this AD.

14 CFR Part 39

[Docket No. FAA-2011-0723; Directorate Identifier 2010-NM-080-AD; 
Amendment 39-16978; AD 2012-05-06]
RIN 2120-AA64


Airworthiness Directives; Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company 
Model L-1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 airplanes. 
That AD currently requires implementation of a Supplemental Inspection 
Document (SID) program of structural inspections to detect fatigue 
cracking, and repair if necessary, to ensure continued airworthiness of 
these airplanes as they approach the manufacturer's original fatigue 
design life goal. This new AD adds Model L-1011-385-3 airplanes to the 
applicability, changes certain inspection thresholds, adds three new 
structurally significant details (SSDs), and removes an SSD that has 
been addressed by a different AD. This AD was prompted by an evaluation 
by the manufacturer of usage and flight data that provided additional 
information about certain SSDs where fatigue damage is likely to occur. 
We are issuing this AD to prevent fatigue cracking that could 
compromise the structural integrity of these airplanes.

DATES: This AD is effective May 10, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 10, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
November 2, 1995 (60 FR 51713, October 3, 1995).

SUPPLEMENTARY INFORMATION: 

[[Page 20523]]

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 95-20-04 R1, Amendment 39-9454 (60 FR 63414, 
December 11, 1995). That AD applies to the specified products. The NPRM 
published in the Federal Register on August 8, 2011 (76 FR 48049). That 
NPRM proposed to continue to require implementation of a SID program of 
structural inspections to detect fatigue cracking, and repair if 
necessary. That NPRM also proposed to add Model L-1011-385-3 airplanes 
to the applicability, change certain inspection thresholds and 
intervals for Model L-1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 
airplanes, include three additional SSDs for Model L-1011-385-3 
airplanes, and remove an SSD that has been addressed by a different AD 
action.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
NPRM (76 FR 48049, August 8, 2011) and the FAA's response to each 
comment.

Request To Withdraw NPRM (76 FR 48049, August 8, 2011)

    An anonymous commenter requested that we stop ``regulating job(s) 
out of this country'' and leave companies alone to run their business 
as they see fit.
    We infer the commenter is requesting that we withdraw the NPRM (76 
FR 48049, August 8, 2011). We disagree. This AD addresses an identified 
unsafe condition. If the structural inspections required by this AD are 
not done, an airplane could develop fatigue cracking that could 
compromise the structural integrity of the airplane. We have not 
revised this AD in this regard.

Request To Clarify Reference

    Lockheed Martin requested that we clarify the section of the 
document referenced in paragraph (g)(5) of the NPRM (76 FR 48049, 
August 8, 2011) by replacing ``Appendix VI'' with ``Section VI., 
Appendix.'' The commenter noted that there is no Appendix VI in the 
document and that there is a section VI titled Appendix.
    We agree, for the reason provided by the commenter. We have revised 
paragraph (g)(5) of this AD accordingly.

Clarification of Repair Service Information

    We have added Note 1 following paragraph (n)(1) of this AD to 
clarify that guidance on doing repairs in accordance with a ``L-1011-
385 Series Supplemental Inspection Document'' specified in paragraph 
(n)(1) of this AD can be found in the applicable service bulletins 
identified in certain SSDs of the ``L-1011-385 Series Supplemental 
Inspection Document.''

Explanation of Changes Made to This AD

    We have revised certain headers throughout this AD. We have also 
revised the wording in paragraph (g) of this AD. These changes have not 
changed the intent of this AD.

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 change described previously--and minor editorial 
changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (76 FR 48049, August 8, 2011) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 48049, August 8, 2011).
    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 26 airplanes of U.S. registry. We 
estimate the following costs 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,

[[Page 20524]]

Part A, Subpart III, Section 44701, ``General requirements.'' Under 
that section, Congress charges the FAA with promoting safe flight of 
civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

certain structurally significant details (SSDs) where fatigue damage 
is likely to occur. We are issuing this AD to prevent fatigue 
cracking that could compromise the structural integrity of these 
airplanes.

(f) Compliance

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

(g) Retained Maintenance Program Revision

    This maintenance program revision is retained from AD 95-20-04 
R1, Amendment 39-9454 (60 FR 63414, December 11, 1995): For Model L-
1011-385-1, L-1011-385-1-14, and L-1011-385-1-15 airplanes: Within 
12 months after November 2, 1995 (the effective date of AD 95-20-04 
R1, Amendment 39-9454 (60 FR 63414, December 11, 1995)), incorporate 
a revision into the maintenance inspection program which provides 
for inspection(s) of the structurally significant details (SSD) 
defined in Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994. Doing the 
revision required by paragraph (h) of this AD terminates the 
requirement to revise the maintenance inspections program specified 
in this paragraph. Doing the inspections required by paragraph (i) 
of this AD terminates the corresponding inspection requirements of 
this paragraph.
    (1) The initial inspection for each SSD must be performed at the 
later of the times specified in paragraph (g)(1)(i) or (g)(1)(ii) of 
this AD.
    (i) Within one repeat interval measured from November 2, 1996 
(12 months after November 2, 1995).
    (ii) Prior to the threshold specified in Lockheed Document 
Number LG92ER0060, ``L-1011-385 Series Supplemental Inspection 
Document,'' revised January 1994, for that SSD.
    (2) A 10 percent deviation from the repetitive interval 
specified in Lockheed Document Number LG92ER0060, ``L-1011-385 
Series Supplemental Inspection Document,'' revised January 1994, for 
that SSD is acceptable to allow for planning and scheduling time.
    (3) If Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994, specifies 
that inspection of any SSD be performed at every ``C'' check, those 
inspections must be performed at intervals not to exceed 5,000 hours 
time-in-service or 2,500 flight cycles, whichever occurs earlier.
    (4) If Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994, specifies 
either the initial inspection or the repetitive inspection intervals 
for any SSD in terms of flight hours or flight cycles, the 
inspection shall be performed prior to the earlier of the terms 
(whichever occurs first on the airplane: either accumulated number 
of flight hours, or accumulated number of flight cycles).
    (5) The non-destructive inspection techniques referenced in 
Section VI., ``Appendix,'' of Lockheed Document Number LG92ER0060, 
``L-1011-385 Series Supplemental Inspection Document,'' revised 
January 1994, provide acceptable methods for accomplishing the 
inspections required by paragraph (g) of this AD.

(h) New Requirements of This AD: Maintenance Program Revision

    For all airplanes: Within 12 months after the effective date of 
this AD, incorporate a revision into the maintenance inspection 
program which provides for inspection(s) of the SSDs defined in 
Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised April 2009. Doing this 
revision terminates the requirement to revise the maintenance 
inspection program as specified in paragraph (g) of this AD.

(i) New Requirement of This AD: Threshold and Intervals

    For all airplanes: Do all applicable inspections specified in 
Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised April 2009. Do the 
initial inspection or next repetitive inspection at the applicable 
time specified in paragraphs (i)(1) and (i)(2) of this AD, except as 
provided by paragraphs (j), (k), and (l) of this AD. Repeat the 
inspections thereafter in accordance with the intervals and actions 
specified in Lockheed Document Number LG92ER0060, ``L-1011-385 
Series Supplemental Inspection Document,'' revised April 2009, 
except as provided by paragraphs (j), (k), and (l) of this AD. The 
non-destructive inspection techniques referenced in Lockheed 
Document Number LG92ER0060, ``L-1011-385 Series Supplemental 
Inspection Document,'' revised April 2009, provide acceptable 
methods for accomplishing the inspections required by this AD. Doing 
the inspections required by this paragraph of this AD terminates the 
corresponding inspection requirements of paragraph (g) of this AD.
    (1) For Model L-1011-385-3 airplanes; and for Model L-1011-385-
1, L-1011-385-1-14, and L-1011-385-1-15 airplanes on which the 
initial inspection required by paragraph (g) of this AD has not been

[[Page 20525]]

accomplished before the effective date of this AD: Do the initial 
inspection at the later of the times specified in paragraphs 
(i)(1)(i) and (i)(1)(ii) of this AD.
    (i) Within one repeat interval measured from a date 12 months 
after the effective date of this AD.
    (ii) Before the threshold specified for that SSD in Lockheed 
Document Number LG92ER0060, ``L-1011-385 Series Supplemental 
Inspection Document,'' revised April 2009.

of this AD has been accomplished before the effective date of this 
AD: Do the next repetitive inspection at the earlier of the times 
specified in paragraphs (i)(2)(i) and (i)(2)(ii) of this AD.
    (i) Within the next repetitive inspection interval specified in 
Lockheed Document Number LG92ER0060, ``L-1011-385 Series 
Supplemental Inspection Document,'' revised January 1994, for that 
SSD.
    (ii) Within one repeat interval measured from a date 12 months 
after the effective date of this AD; or within the next repetitive 
interval specified in Lockheed Document Number LG92ER0060, ``L-1011-
385 Series Supplemental Inspection Document,'' revised April 2009, 
for that SSD; whichever occurs later.

(j) Exception to Intervals--10 Percent Deviation Allowed

    For all airplanes: A 10 percent deviation from the repetitive 
interval specified in Lockheed Document Number LG92ER0060, ``L-1011-
385 Series Supplemental Inspection Document,'' revised April 2009, 
for that SSD is acceptable to allow for planning and scheduling 
time.

(k) Exception to Intervals Specifying ``C'' Check

    For all airplanes: Where Lockheed Document Number LG92ER0060, 
``L-1011-385 Series Supplemental Inspection Document,'' revised 
April 2009, specifies that inspection of any SSD be performed at 
every ``C'' check, those inspections must be performed at intervals 
not to exceed 5,000 flight hours or 2,500 flight cycles, whichever 
occurs earlier.

(l) Exceptions to Threshold and Intervals

    For all airplanes: Where Lockheed Document Number LG92ER0060, 
``L-1011-385 Series Supplemental Inspection Document,'' revised 
April 2009, specifies either the initial inspection or the 
repetitive inspection intervals for any SSD in terms of flight hours 
or flight cycles, the inspection must be performed prior to the 
earlier of the terms (whichever occurs first on the airplane: either 
accumulated number of flight hours, or accumulated number of flight 
cycles).

(m) Exception to Inspection Procedure

    For all airplanes: There should be no repair or modification 
work done in the inspection area before the initial inspections 
required by paragraph (i) of this AD; any changes in the inspection 
area could affect the inspection procedure.

(n) New Requirements of This AD: Repair

    For all airplanes: If any cracking is found in any SSD during 
any inspection required by this AD, prior to further flight, repair 
in accordance with paragraph (n)(1), (n)(2), or (n)(3) of this AD:
    (1) In accordance with the Lockheed Document Number LG92ER0060, 
``L-1011-385 Series Supplemental Inspection Document,'' revised
