ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L–1011 series airplanes. The existing AD currently requires repetitive inspections to detect corrosion or fatigue cracking of certain structural elements of the airplane; corrective actions if necessary; and incorporation of certain structural modifications. Since we issued that AD, we have received reports of small cracks in additional areas outside those addressed in the existing AD, prior to the inspection threshold required by the existing AD. This proposed AD would reduce certain compliance times for the initial inspection, and the repetitive inspection interval for certain airplanes. We are proposing this AD to prevent corrosion or fatigue cracking of certain SUMMARY: PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 63275 structural elements, which could result in reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by November 30, 2012.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On July 8, 2005, we issued AD 2005– 15–01, Amendment 39–14191 (70 FR 42262, July 22, 2005), for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L–1011 series airplanes. That AD requires repetitive inspections to detect corrosion or fatigue cracking of certain structural elements of the airplane; corrective actions if necessary; and incorporation of certain structural modifications. That AD resulted from new recommendations related to incidents of fatigue cracking and corrosion in transport category airplanes that are approaching or have exceeded their economic design goal. We issued that AD to prevent corrosion or fatigue cracking of certain structural elements, which could result in reduced structural integrity of the airplane. Actions Since Existing AD Was Issued Since we issued AD 2005–15–01, Amendment 39–14191 (70 FR 42262, July 22, 2005), we have received reports of small cracks found outside the areas addressed by the existing AD. Specifically, these cracks were found from inner wing station (IWS) 477.70 to IWS 372.64 (inboard) and from outer wing station (OWS) 52.2 to OWS 296.5 (outboard). Relevant Service Information AD 2005–15–01, Amendment 39– 14191 (70 FR 42262, July 22, 2005), refers to Lockheed Tristar L–1011 Service Bulletin 093–51–041, Revision 1, dated March 3, 2000 (a ‘‘collector service bulletin’’), as the appropriate source of service information for the required actions. This service bulletin has since been revised. We have reviewed Lockheed Service Bulletin 093–51–041, Revision 2, dated March 30, 2010, which, in turn, refers to Lockheed Service Bulletin 093–57–195, now at Revision 4, dated March 17, 2010. Lockheed Service Bulletin 093–57– 195, Revision 4, dated March 17, 2010, includes the following changes: • Supersedes Lockheed Service Bulletin 093–57–069, Revision 4, dated October 5, 1998. • Reduces the initial inspection threshold to 15,000 flight cycles; or 15,000 flight cycles after incorporation of Lockheed Service Bulletin 093–57– 069, Revision 4, dated October 5, 1998. • Reduces the repetitive inspection interval to 1,750 flight cycles for Model L–1011–385–3 airplanes. • Changes the fastener hole cold working procedure from ‘‘FTI–LCC– 8701’’ to ‘‘FTI–LASC–51–20–01.’’ FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would retain all requirements of AD 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005). This proposed AD would reduce the initial inspection threshold for certain airplanes for accomplishment of the actions specified in Lockheed Service Bulletin 093–57–195, Revision 4, dated March 17, 2010, and would reduce the repetitive inspection interval for Model L–1011–385–3 airplanes. This proposed AD would also require accomplishing the actions specified in the service information described previously. Changes to Existing AD This proposed AD would retain all requirements of AD 2005–15–01, Amendment 39–14191 (70 FR 42262, July 22, 2005). Since AD 2005–15–01 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 2005–15–01, Amendment 39-14190 (70 FR 42262, July 22, 2005) Corresponding requirement in this proposed AD paragraph (a) paragraph (b) paragraph (c) paragraph (g). paragraph (h). paragraph (i). In addition, we have removed paragraph (b)(2) from AD 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005), and added a new sentence to paragraph (h)(3) of this proposed AD to specify that information on additional methods of compliance can be obtained from the Manager, Atlanta Aircraft Certification Office (ACO). We might decide to approve certain sections of the Lockheed L–1011 structural repair manual as an alternative method of compliance with this proposed AD, as provided by paragraph (l) of this proposed AD. We have also revised the applicability of the existing AD 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005), to identify model designations as published in the most recent type certificate data sheet for the affected models. Costs of Compliance We estimate that this proposed AD affects 26 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS pmangrum on DSK3VPTVN1PROD with PROPOSALS-1 Action Labor cost Inspections [retained actions from existing 2005–15–01, Amendment 39–14191 (70 42262, July 22, 2005)].

E:\FR\FM\16OCP1.SGM 16OCP1 Federal Register / Vol. 77, No. 200 / Tuesday, October 16, 2012 / Proposed Rules We have received no definitive data that would enable us to provide cost estimates for the retained on-condition actions specified in this proposed 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 We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), 63277 (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. 385–1–14, L–1011–385–1–15, and L–1011– 385–3 airplanes; certificated in any category. List of Subjects in 14 CFR Part 39 (e) Unsafe Condition Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. This AD was prompted by reports of small cracks in additional areas outside those addressed in the existing AD (AD 2005–15– 01, Amendment 39–14190 (70 FR 42262, July 22, 2005)), prior to the inspection threshold required by the existing AD. We are issuing this AD to prevent corrosion or fatigue cracking of certain structural elements, which could result in reduced structural integrity of the airplane. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: Joint Aircraft System Component (JASC)/ Air Transport Association (ATA) of America Code 51, Standard practices/structures; 52, Doors; 53, Fuselage; 57, Wings. (f) Compliance PART 39—AIRWORTHINESS DIRECTIVES Comply with this AD within the compliance times specified, unless already done. 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 (d) Subject [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005), and adding the following new AD: Lockheed Martin Corporation/Lockheed Martin Aeronautics Company: Docket No. FAA–2012–1078; Directorate Identifier 2011–NM–012–AD. (a) Comments Due Date The FAA must receive comments on this AD action by November 30, 2012. (b) Affected ADs This AD supersedes AD 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005). (c) Applicability This AD applies to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L–1011–385–1, L–1011– (g) Retained Inspections With Revised Service Information and Reduced Compliance Times This paragraph restates the inspection required by paragraph (a) of AD 2005–15–01, Amendment 39–14190 (70 FR 42262, July 22, 2005), with revised service information and reduced compliance times for paragraph (g)(16) of this AD. At the time specified in the ‘‘Initial Compliance Time’’ column of table 1 to paragraph (g) of this AD, perform structural inspections to detect corrosion or fatigue cracking of certain structural elements of the airplane, in accordance with the applicable service bulletins listed under ‘‘Service Bulletin Number, Revision, and Date’’ in tables I and II of Lockheed Tristar L–1011 Service Bulletin 093–51–041, Revision 1, dated March 3, 2000, or Revision 2, dated March 30, 2010. As of the effective date of this AD, only Lockheed Tristar L– 1011 Service Bulletin 093–51–041, Revision 2, dated March 30, 2010, may be used for the actions required by this paragraph. Thereafter, repeat the inspections at intervals specified in the ‘‘Repetitive Intervals’’ column of table 1 to paragraph (g) of this AD.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2012–22, dated July 24, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: There have been two reported in-service incidents where the left main landing gear PO 00000 Frm 00028 Fmt 4702 Sfmt 4702 63281 (MLG) failed to extend. The investigation revealed that in both cases, the uplock assembly had been replaced prior to the inservice incidents and the upper bolt of the uplock assembly was incorrectly installed. The incorrect installation of the upper bolt resulted in the uplock assembly pivoting on the lower attachment bolt and preventing the MLG from extending under normal or alternate extension The potential for an incorrect installation of the upper bolt could occur at both the left hand side (LHS) and/or the right hand side (RHS) MLG uplock assembly. Failure of the MLG to extend could adversely affect the safe landing of the aeroplane. This [Canadian] AD mandates the installation of stopper plates on the aft uplock frames in the MLG bay, adjacent to both the RHS and LHS MLG uplock assemblies, to prevent an incorrect installation of the MLG uplock assembly. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier, Inc. has issued Service Bulletin 601R–32–109, dated May 29, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 574 products of U.S. registry. We also estimate that it would take about 5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $243,950, or $425 per product. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to all Lockheed Martin Corporation/Lockheed Martin
Aeronautics Company Model L-1011 series airplanes. The existing AD
currently requires repetitive inspections to detect corrosion or
fatigue cracking of certain structural elements of the airplane;
corrective actions if necessary; and incorporation of certain
structural modifications. Since we issued that AD, we have received
reports of small cracks in additional areas outside those addressed in
the existing AD, prior to the inspection threshold required by the
existing AD. This proposed AD would reduce certain compliance times for
the initial inspection, and the repetitive inspection interval for
certain airplanes. We are proposing this AD to prevent corrosion or
fatigue cracking of certain structural elements, which could result in
reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by November 30,
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

On July 8, 2005, we issued AD 2005-15-01, Amendment 39-14191 (70 FR
42262, July 22, 2005), for all Lockheed Martin Corporation/Lockheed
Martin Aeronautics Company Model L-1011 series airplanes. That AD
requires repetitive inspections to detect corrosion or fatigue cracking
of certain structural elements of the airplane; corrective actions if
necessary; and incorporation of certain structural modifications. That
AD resulted from new recommendations related to incidents of fatigue
cracking and corrosion in transport category airplanes that are
approaching or have exceeded their economic design goal. We issued that
AD to prevent corrosion or fatigue cracking of certain structural
elements, which could result in reduced structural integrity of the
airplane.

Actions Since Existing AD Was Issued

Since we issued AD 2005-15-01, Amendment 39-14191 (70 FR 42262,
July 22, 2005), we have received reports of small cracks found outside
the areas addressed by the existing AD. Specifically, these cracks were
found from inner wing station (IWS) 477.70 to IWS 372.64 (inboard) and
from outer wing station (OWS) 52.2 to OWS 296.5 (outboard).

Relevant Service Information

AD 2005-15-01, Amendment 39-14191 (70 FR 42262, July 22, 2005),
refers to Lockheed Tristar L-1011 Service Bulletin 093-51-041, Revision
1, dated March 3, 2000 (a ``collector service bulletin''), as the
appropriate source of service information for the required actions.
This service bulletin has since been revised. We have reviewed Lockheed
Service Bulletin 093-51-041, Revision 2, dated March 30, 2010, which,
in turn, refers to Lockheed Service Bulletin 093-57-195, now at
Revision 4, dated March 17, 2010.
Lockheed Service Bulletin 093-57-195, Revision 4, dated March 17,
2010, includes the following changes:
Supersedes Lockheed Service Bulletin 093-57-069, Revision
4, dated October 5, 1998.
Reduces the initial inspection threshold to 15,000 flight
cycles; or 15,000 flight cycles after incorporation of Lockheed Service
Bulletin 093-57-069, Revision 4, dated October 5, 1998.
Reduces the repetitive inspection interval to 1,750 flight
cycles for Model L-1011-385-3 airplanes.
Changes the fastener hole cold working procedure from
``FTI-LCC-8701'' to ``FTI-LASC-51-20-01.''

FAA's Determination

We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs.

Proposed AD Requirements

This proposed AD would retain all requirements of AD 2005-15-01,
Amendment 39-14190 (70 FR 42262, July 22, 2005). This proposed AD would
reduce the initial inspection threshold for certain airplanes for
accomplishment of the actions specified in Lockheed Service Bulletin
093-57-195, Revision 4, dated March 17, 2010, and would reduce the
repetitive inspection interval for Model L-1011-385-3 airplanes. This
proposed AD would also require accomplishing the actions specified in
the service information described previously.

Changes to Existing AD

This proposed AD would retain all requirements of AD 2005-15-01,
Amendment 39-14191 (70 FR 42262, July 22, 2005). Since AD 2005-15-01
was issued, the AD format has been revised, and certain paragraphs have
been rearranged. As a result, the corresponding paragraph identifiers
have changed in this proposed AD, as listed in the following table:

Revised Paragraph Identifiers
------------------------------------------------------------------------
Requirement in AD 2005-15-01,
Amendment 39[dash]14190 (70 FR Corresponding requirement in this
42262, July 22, 2005) proposed AD
------------------------------------------------------------------------
paragraph (a) paragraph (g).
paragraph (b) paragraph (h).
paragraph (c) paragraph (i).
------------------------------------------------------------------------

In addition, we have removed paragraph (b)(2) from AD 2005-15-01,
Amendment 39-14190 (70 FR 42262, July 22, 2005), and added a new
sentence to paragraph (h)(3) of this proposed AD to specify that
information on additional methods of compliance can be obtained from
the Manager, Atlanta Aircraft Certification Office (ACO). We might
decide to approve certain sections of the Lockheed L-1011 structural
repair manual as an alternative method of compliance with this proposed
AD, as provided by paragraph (l) of this proposed AD.
We have also revised the applicability of the existing AD 2005-15-
01, Amendment 39-14190 (70 FR 42262, July 22, 2005), to identify model
designations as published in the most recent type certificate data
sheet for the affected models.

Costs of Compliance

We estimate that this proposed AD affects 26 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:

We have received no definitive data that would enable us to provide
cost estimates for the retained on-condition actions specified in this
proposed 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

We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

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

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

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by removing airworthiness directive
(AD) 2005-15-01, Amendment 39-14190 (70 FR 42262, July 22, 2005), and
adding the following new AD:

Lockheed Martin Corporation/Lockheed Martin Aeronautics Company:
Docket No. FAA-2012-1078; Directorate Identifier 2011-NM-012-AD.

(a) Comments Due Date

The FAA must receive comments on this AD action by November 30,
2012.

(b) Affected ADs

This AD supersedes AD 2005-15-01, Amendment 39-14190 (70 FR
42262, July 22, 2005).

This AD applies to all Lockheed Martin Corporation/Lockheed
Martin Aeronautics Company Model L-1011-385-1, L-1011-385-1-14, L-
1011-385-1-15, and L-1011-385-3 airplanes; certificated in any
category.

(d) Subject

Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 51, Standard practices/structures; 52, Doors;
53, Fuselage; 57, Wings.

(e) Unsafe Condition

This AD was prompted by reports of small cracks in additional
areas outside those addressed in the existing AD (AD 2005-15-01,
Amendment 39-14190 (70 FR 42262, July 22, 2005)), prior to the
inspection threshold required by the existing AD. We are issuing
this AD to prevent corrosion or fatigue cracking of certain
structural elements, which could result in reduced structural
integrity of the airplane.

(f) Compliance

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

(g) Retained Inspections With Revised Service Information and Reduced
Compliance Times

This paragraph restates the inspection required by paragraph (a)
of AD 2005-15-01, Amendment 39-14190 (70 FR 42262, July 22, 2005),
with revised service information and reduced compliance times for
paragraph (g)(16) of this AD. At the time specified in the ``Initial
Compliance Time'' column of table 1 to paragraph (g) of this AD,
perform structural inspections to detect corrosion or fatigue
cracking of certain structural elements of the airplane, in
accordance with the applicable service bulletins listed under
``Service Bulletin Number, Revision, and Date'' in tables I and II
of Lockheed Tristar L-1011 Service Bulletin 093-51-041, Revision 1,
dated March 3, 2000, or Revision 2, dated March 30, 2010. As of the
effective date of this AD, only Lockheed Tristar L-1011 Service
Bulletin 093-51-041, Revision 2, dated March 30, 2010, may be used
for the actions required by this paragraph. Thereafter, repeat the
inspections at intervals specified in the ``Repetitive Intervals''
column of table 1 to paragraph (g) of this AD.
