ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to all Lockheed Model
L–1011 series airplanes. That AD
currently requires an inspection of the
fuel level control switch, the fuel level
control switch wiring harness, and the
wiring harness conduit for damage,
wear or chafing, broken or missing Orings, or indications of electrical arcing.
That AD also requires replacement of a

certain conduit in the fuel level control
switch wiring harness, installation of
electrical sleeving over the fuel level
control switch wiring harness, and
installation of the fuel level control
switch that has been so modified. This
new AD requires an inspection of the
fuel level control switch, wiring
harnesses, and harness conduit for any
visible damage, wear or chafing, broken
or missing O-rings, or indications of
electrical arcing; an inspection to
determine the part number of the wiring
harness conduit; and corrective actions
if necessary. This new AD also requires
replacing certain sleeving with new,
improved sleeving over the wiring
harness of the fuel level control switch.
This AD results from a design review of
the fuel tank systems. We are issuing
this AD to prevent chafing of the fuel
level control switch wiring harness,
which could cause arcing and result in
a fire in the fuel tank.
DATES: This AD becomes effective July
23, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain other publication listed in
the AD as of July 23, 2008.
On June 1, 2001 (66 FR 21072, April
27, 2001), the Director of the Federal
Register approved the incorporation by
reference of a certain service bulletin.

Federal Register / Vol. 73, No. 118 / Wednesday, June 18, 2008 / Rules and Regulations
Discussion
On April 18, 2001, we issued AD
2001–08–21, amendment 39–12198 (66
FR 21072, April 27, 2001), for all
Lockheed Model L–1011 series
airplanes. That AD requires a general
visual inspection of the fuel level
control switch, the fuel level control
switch wiring harness, and the wiring
harness conduit for damage, wear or
chafing, broken or missing O-rings, or
indications of electrical arcing. That AD
also requires replacement of a certain
conduit in the fuel level control switch
wiring harness, installation of electrical
sleeving over the fuel level control
switch wiring harness, and installation
of the fuel level control switch that has
been so modified. That AD resulted
from a design review of the fuel tank
systems. We issued that AD to prevent
chafing of the fuel level control switch
wiring harness, which could cause
arcing and result in a fire in the fuel
tank. That AD refers to the original issue
of Lockheed Service Bulletin 093–28–
094, dated March 3, 2000, as the
appropriate source of service
information for accomplishing the
actions required by that AD.
specified in Revision 1 of Lockheed
Service Bulletin 093–28–094. The
commenter further requested that we
instead issue a separate rulemaking
action to supersede AD 2001–08–21 to
require the accomplishment of Revision
1 of the service bulletin. As stated in the
NPRM, AD 2001–08–21 requires the
accomplishment of the original issue of
the service bulletin, but more work is
necessary for Revision 1 of the service
bulletin. The additional work includes
replacing any wiring harness conduit
having part number (P/N) 741652–105
with new conduit having P/N 741652–
121, removing any braided fiberglass
sleeving installed in accordance with
the original issue of the service bulletin,
and installing PVC electrical sleeving
having P/N PVC–105–2 over the wiring
harness of the fuel level control switch.
We agree that it is more appropriate
to supersede AD 2001–08–21 to require
the additional work specified in
Revision 1 of the service bulletin.
Therefore, we are issuing this new
action to amend 14 CFR part 39 to
include an AD that supersedes AD
2001–08–21. Further, we also removed
the proposed requirement to accomplish
the FSL specified in Revision 1 of the
service bulletin from the NPRM, and we
issued AD 2008–11–02, amendment 39–
15524 (73 FR 29410, May 21, 2008), on
May 8, 2008, to require all other actions
proposed by the NPRM.
Actions Since Existing AD Was Issued
Since we issued AD 2001–08–21, 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,
Docket No. FAA–2008–0181, 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 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. One of those FSLs involved
accomplishing the actions specified in
Lockheed Service Bulletin 093–28–094,
Revision 1, dated June 23, 2006.
We gave the public the opportunity to
participate in developing that NPRM,
and we received a comment from ATA
Airlines requesting that we revise the
NPRM by removing the proposed
requirement to accomplish the FSL
Relevant Service Information
We have reviewed Revision 1 of
Lockheed Service Bulletin 093–28–094.
That service bulletin describes the
following procedures:
• Inspecting the fuel level control
switch, wiring harness, and wiring
harness conduit for any visible damage,
wear or chafing, broken or missing Orings, or indications of electrical arcing.
• Verifying the part number of the
wiring harness conduit.
• Removing any braided fiberglass
sleeving installed in accordance with
the original issue of the service bulletin,
and installing PVC electrical sleeving
having P/N PVC–105–2 over the wiring
harness of the fuel level control switch.
• Doing corrective actions if
necessary.
The corrective actions include
replacing the fuel level control switch
with a new part if any visible damage,
wear or chafing, broken or missing Oring, or indication of electrical arcing is
found; and replacing any wiring harness
conduit having P/N 741652–103 or -105
with new conduit having P/N 741652–
121.
The service bulletin also describes
procedures for notifying Lockheed of
any discrepancies found during the

inspection, and revising the airplane
records and maintenance planning
documents to repeat the inspection at
intervals not to exceed 120 months.
FAA’s Determination and Requirements
of the AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to develop on
other airplanes of the same type design.
For this reason, we are issuing this AD,
which would supersede AD 2001–08–21
and would retain the requirements of
the existing AD. This AD would also
require the following actions:
• A general visual inspection of the
fuel level control switch, wiring
harness, and wiring harness conduit for
any visible damage, wear or chafing,
broken or missing O-rings, or
indications of electrical arcing, and
corrective action as applicable.
• An inspection to determine the part
number of the wiring harness conduit,
and corrective action as applicable.
• Replacement of any braided
fiberglass sleeving with PVC electrical
sleeving over the wiring harness of the
fuel level control switch.
• A revision to the FAA-approved
maintenance program to incorporate
repetitive general visual inspections of
the fuel level control switch, wiring
harness, and wiring harness conduit for
any visible damage, wear or chafing,
broken or missing O-rings, or
indications of electrical arcing.
This AD allows accomplishing the
revision to the FAA-approved
maintenance program in accordance
with later revisions of Lockheed Service
Bulletin 093–28–094 as an acceptable
method of compliance if they are
approved by the Manager, Atlanta
Aircraft Certification Office, FAA.
Difference Between This AD and
Service Bulletin
Although Lockheed Service Bulletin
093–28–094, Revision 1, describes
procedures for notifying Lockheed of
any discrepancies found during the
inspection, this AD does not require that
action.
Clarification of Inspection Terminology
The ‘‘inspection’’ specified in
Lockheed Service Bulletin 093–28–094,
Revision 1, is referred to as a ‘‘general
visual inspection’’ in this AD. We have
included the definition for a general
visual inspection in a note in this AD.
Change to Existing AD
This AD retains all requirements of
AD 2001–08–21. Since AD 2001–08–21
was issued, the AD format has been
revised, and certain paragraphs have
E:\FR\FM\18JNR1.SGM

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.

SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
During a flight test performed on an EASy
aircraft, subsequently to an air data probe
failure, the crew realized that the Flight path
vectors and the Vertical speeds that were
displayed on pilot’s and co-pilot’s PDU
(primary display unit) were identically
wrong.
A review of the EASy architecture reveals
that * * * One single ADS (air data system)
unflagged air data error may lead to the

Airworthiness Directives; Lockheed Model L-1011 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to all Lockheed Model L-1011 series airplanes. That
AD currently requires an inspection of the fuel level control switch,
the fuel level control switch wiring harness, and the wiring harness
conduit for damage, wear or chafing, broken or missing O-rings, or
indications of electrical arcing. That AD also requires replacement of
a certain conduit in the fuel level control switch wiring harness,
installation of electrical sleeving over the fuel level control switch
wiring harness, and installation of the fuel level control switch that
has been so modified. This new AD requires an inspection of the fuel
level control switch, wiring harnesses, and harness conduit for any
visible damage, wear or chafing, broken or missing O-rings, or
indications of electrical arcing; an inspection to determine the part
number of the wiring harness conduit; and corrective actions if
necessary. This new AD also requires replacing certain sleeving with
new, improved sleeving over the wiring harness of the fuel level
control switch. This AD results from a design review of the fuel tank
systems. We are issuing this AD to prevent chafing of the fuel level
control switch wiring harness, which could cause arcing and result in a
fire in the fuel tank.
DATES: This AD becomes effective July 23, 2008.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in the AD as of July
23, 2008.
On June 1, 2001 (66 FR 21072, April 27, 2001), the Director of the
Federal Register approved the incorporation by reference of a certain
service bulletin.

SUPPLEMENTARY INFORMATION:
Discussion
On April 18, 2001, we issued AD 2001-08-21, amendment 39-12198 (66
FR 21072, April 27, 2001), for all Lockheed Model L-1011 series
airplanes. That AD requires a general visual inspection of the fuel
level control switch, the fuel level control switch wiring harness, and
the wiring harness conduit for damage, wear or chafing, broken or
missing O-rings, or indications of electrical arcing. That AD also
requires replacement of a certain conduit in the fuel level control
switch wiring harness, installation of electrical sleeving over the
fuel level control switch wiring harness, and installation of the fuel
level control switch that has been so modified. That AD resulted from a
design review of the fuel tank systems. We issued that AD to prevent
chafing of the fuel level control switch wiring harness, which could
cause arcing and result in a fire in the fuel tank. That AD refers to
the original issue of Lockheed Service Bulletin 093-28-094, dated March
3, 2000, as the appropriate source of service information for
accomplishing the actions required by that AD.
Actions Since Existing AD Was Issued
Since we issued AD 2001-08-21, 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, Docket No. FAA-2008-0181, 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 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. One of those FSLs involved
accomplishing the actions specified in Lockheed Service Bulletin 093-
28-094, Revision 1, dated June 23, 2006.
We gave the public the opportunity to participate in developing
that NPRM, and we received a comment from ATA Airlines requesting that
we revise the NPRM by removing the proposed requirement to accomplish
the FSL specified in Revision 1 of Lockheed Service Bulletin 093-28-
094. The commenter further requested that we instead issue a separate
rulemaking action to supersede AD 2001-08-21 to require the
accomplishment of Revision 1 of the service bulletin. As stated in the
NPRM, AD 2001-08-21 requires the accomplishment of the original issue
of the service bulletin, but more work is necessary for Revision 1 of
the service bulletin. The additional work includes replacing any wiring
harness conduit having part number (P/N) 741652-105 with new conduit
having P/N 741652-121, removing any braided fiberglass sleeving
installed in accordance with the original issue of the service
bulletin, and installing PVC electrical sleeving having P/N PVC-105-2
over the wiring harness of the fuel level control switch.
We agree that it is more appropriate to supersede AD 2001-08-21 to
require the additional work specified in Revision 1 of the service
bulletin. Therefore, we are issuing this new action to amend 14 CFR
part 39 to include an AD that supersedes AD 2001-08-21. Further, we
also removed the proposed requirement to accomplish the FSL specified
in Revision 1 of the service bulletin from the NPRM, and we issued AD
2008-11-02, amendment 39-15524 (73 FR 29410, May 21, 2008), on May 8,
2008, to require all other actions proposed by the NPRM.
Relevant Service Information
We have reviewed Revision 1 of Lockheed Service Bulletin 093-28-
094. That service bulletin describes the following procedures:
Inspecting the fuel level control switch, wiring harness,
and wiring harness conduit for any visible damage, wear or chafing,
broken or missing O-rings, or indications of electrical arcing.
Verifying the part number of the wiring harness conduit.
Removing any braided fiberglass sleeving installed in
accordance with the original issue of the service bulletin, and
installing PVC electrical sleeving having P/N PVC-105-2 over the wiring
harness of the fuel level control switch.
Doing corrective actions if necessary.
The corrective actions include replacing the fuel level control
switch with a new part if any visible damage, wear or chafing, broken
or missing O-ring, or indication of electrical arcing is found; and
replacing any wiring harness conduit having P/N 741652-103 or -105 with
new conduit having P/N 741652-121.
The service bulletin also describes procedures for notifying
Lockheed of any discrepancies found during the inspection, and revising
the airplane records and maintenance planning documents to repeat the
inspection at intervals not to exceed 120 months.
FAA's Determination and Requirements of the AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to develop on other airplanes of the
same type design. For this reason, we are issuing this AD, which would
supersede AD 2001-08-21 and would retain the requirements of the
existing AD. This AD would also require the following actions:
A general visual inspection of the fuel level control
switch, wiring harness, and wiring harness conduit for any visible
damage, wear or chafing, broken or missing O-rings, or indications of
electrical arcing, and corrective action as applicable.
An inspection to determine the part number of the wiring
harness conduit, and corrective action as applicable.
Replacement of any braided fiberglass sleeving with PVC
electrical sleeving over the wiring harness of the fuel level control
switch.
A revision to the FAA-approved maintenance program to
incorporate repetitive general visual inspections of the fuel level
control switch, wiring harness, and wiring harness conduit for any
visible damage, wear or chafing, broken or missing O-rings, or
indications of electrical arcing.
This AD allows accomplishing the revision to the FAA-approved
maintenance program in accordance with later revisions of Lockheed
Service Bulletin 093-28-094 as an acceptable method of compliance if
they are approved by the Manager, Atlanta Aircraft Certification
Office, FAA.
Difference Between This AD and Service Bulletin
Although Lockheed Service Bulletin 093-28-094, Revision 1,
describes procedures for notifying Lockheed of any discrepancies found
during the inspection, this AD does not require that action.
Clarification of Inspection Terminology
The ``inspection'' specified in Lockheed Service Bulletin 093-28-
094, Revision 1, is referred to as a ``general visual inspection'' in
this AD. We have included the definition for a general visual
inspection in a note in this AD.
Change to Existing AD
This AD retains all requirements of AD 2001-08-21. Since AD 2001-
08-21 was issued, the AD format has been revised, and certain
paragraphs have
[[Page 34607]]
been rearranged. As a result, the corresponding paragraph identifiers
have changed in this AD, as listed in the following table:

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 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
