situation to materialize. These
conditions include, but are not limited
to, artificial insemination technology
becoming a more cost-effective
approach to sheep and goat production
versus using breeding animals.
Essentially, the only way sheep and goat
breeders would be affected over the long
run is if the process of artificial
insemination becomes cheaper than
purchasing or maintaining replacement
breeding animals. As of January 1, 2005,
there were inventories of 4.53 million
head of breeding sheep and 2.1 million
head of breeding goats in the United
States. Thus, it is possible that, as the
process of artificial insemination
becomes more cost-effective and as
imported sheep semen becomes more
readily available and technologies
improve, sheep and goat producers will
substitute away from buying
replacement breeding animals and use
artificial insemination instead.
However, as stated previously, this
situation is long-term in nature and
highly conditional.
Under these circumstances, the
Administrator of the Animal and Plant
Health Inspection Service has
determined that this action would not
have a significant economic impact on
a substantial number of small entities.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Lockheed Model L–1011 series
airplanes. This proposed AD would
require a one-time detailed inspection of
the C112 harness clamp assembly for
proper installation, a one-time detailed
inspection of the C112 and C162
harness assemblies for damage, and
corrective actions if necessary. This
proposed AD results from a report of
electrical arcing of the essential bus
feeder cables behind hinged circuit
breaker panel CB3 P–K. We are
proposing this AD to prevent arcing of
essential bus feeder cables due to
improper installation of the harness
C112 clamp assembly, which could
result in loss of electrical systems and
smoke and/or fire behind the CB3 P–K
hinged circuit breaker panel in the flight
compartment.
DATES: We must receive comments on
this proposed AD by September 25,
2006.

Discussion
We have received a report of electrical
arcing of the essential bus feeder cables
behind hinged circuit breaker panel CB3
P–K that occurred during maintenance,
causing extensive damage to the
surrounding area, on a Lockheed Model
L–1011 series airplane. Investigation of
the arcing revealed that the cushion
clamp securing wire harness assembly
C112 was installed incorrectly, with the
clamp loop on the forward side instead
of the aft side of the clamp screw. The
improper installation of the cushion
clamp allowed the clamp to chafe
against the C162 wire harness. We have
also received a report indicating that
two additional airplanes have been
found with improperly installed
cushion clamps at this location. This
condition, if not corrected, could result
in loss of electrical systems and smoke
and/or fire behind the CB3 P–K hinged
circuit breaker panel in the flight
compartment.
Relevant Service Information
We have reviewed Lockheed L–1011
Service Bulletin 093–24–142, dated
November 16, 2005. The service bulletin
describes procedures for a one-time
detailed inspection of the circuit breaker
panel clamp assembly for harness C112
just outboard of terminal block 2400
TB17 in the hinged circuit breaker panel
CB3 P–K to verify the position of the
clamp assembly. It also describes
procedures for a one-time detailed
inspection of the C112 and C162
harness assemblies for damage (e.g.,
evidence of chafing, arcing, or
deterioration), and corrective actions if
necessary. The corrective actions
include repositioning the clamp
assembly to the correct position and
correcting damage found in the C112
and C162 harness assemblies.
Accomplishing the actions specified in
the service information is intended to
adequately address the unsafe
condition.
FAA’s Determination and Requirements
of the Proposed AD
We have evaluated all pertinent
information and identified an unsafe
condition that is likely to exist or
develop on other airplanes of this same
type design. For this reason, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Difference Between the Proposed AD
and the Service Bulletin.’’
Difference Between the Proposed AD
and the Service Bulletin
Although the service bulletin
recommends accomplishing the
inspection of the circuit breaker panel
clamp assembly for harness C112 ‘‘at the
next scheduled maintenance visit,’’ we
have determined that this imprecise
compliance time would not address the
identified unsafe condition in a timely
manner. In developing an appropriate
compliance time for this proposed AD,
we considered not only the
manufacturer’s recommendation, but
also the degree of urgency associated
with addressing the subject unsafe
condition, the average utilization of the
affected fleet, and the time necessary to
perform the inspection. In light of all of
these factors, we find a compliance time
of 90 days for completing the required
actions to be warranted, in that it
represents an appropriate interval of
time for affected airplanes to continue to
operate without compromising safety.
This difference has been coordinated
with Lockheed.
Costs of Compliance
There are about 126 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD.

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.
Affected ADs
Regulatory Findings
Unsafe Condition
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); 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 proposed AD and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.
(d) This AD results from a report of
electrical arcing of the essential bus feeder
cables behind hinged circuit breaker panel
CB3 P-K. We are issuing this AD to prevent
arcing of essential bus feeder cables due to
improper installation of the harness C112
clamp assembly, which could result in loss
of electrical systems and smoke and/or fire
behind the CB3 P-K hinged circuit breaker
panel in the flight compartment.

Discussion
We have received a report of electrical arcing of the essential bus
feeder cables behind hinged circuit breaker panel CB3 P-K that occurred
during maintenance, causing extensive damage to the surrounding area,
on a Lockheed Model L-1011 series airplane. Investigation of the arcing
revealed that the cushion clamp securing wire harness assembly C112 was
installed incorrectly, with the clamp loop on the forward side instead
of the aft side of the clamp screw. The improper installation of the
cushion clamp allowed the clamp to chafe against the C162 wire harness.
We have also received a report indicating that two additional airplanes
have been found with improperly installed cushion clamps at this
location. This condition, if not corrected, could result in loss of
electrical systems and smoke and/or fire behind the CB3 P-K hinged
circuit breaker panel in the flight compartment.
Relevant Service Information
We have reviewed Lockheed L-1011 Service Bulletin 093-24-142, dated
November 16, 2005. The service bulletin describes procedures for a one-
time detailed inspection of the circuit breaker panel clamp assembly
for harness C112 just outboard of terminal block 2400 TB17 in the
hinged circuit breaker panel CB3 P-K to verify the position of the
clamp assembly. It also describes procedures for a one-time detailed
inspection of the C112 and C162 harness assemblies for damage (e.g.,
evidence of chafing, arcing, or deterioration), and corrective actions
if necessary. The corrective actions include repositioning the clamp
assembly to the correct position and correcting damage found in the
C112 and C162 harness assemblies. Accomplishing the actions specified
in the service information is intended to adequately address the unsafe
condition.
FAA's Determination and Requirements of the Proposed AD
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Difference Between the Proposed AD and the Service Bulletin.''
Difference Between the Proposed AD and the Service Bulletin
Although the service bulletin recommends accomplishing the
inspection of the circuit breaker panel clamp assembly for harness C112
``at the next scheduled maintenance visit,'' we have determined that
this imprecise compliance time would not address the identified unsafe
condition in a timely manner. In developing an appropriate compliance
time for this proposed AD, we considered not only the manufacturer's
recommendation, but also the degree of urgency associated with
addressing the subject unsafe condition, the average utilization of the
affected fleet, and the time necessary to perform the inspection. In
light of all of these factors, we find a compliance time of 90 days for
completing the required actions to be warranted, in that it represents
an appropriate interval of time for affected airplanes to continue to
operate without compromising safety. This difference has been
coordinated with Lockheed.
Costs of Compliance
There are about 126 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with 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
[[Page 45449]]
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); 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 proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, 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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Lockheed: Docket No. FAA-2006-25554; Directorate Identifier 2006-NM-
123-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by September
25, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Lockheed Model L-1011-385-1, L-1011-385-
1-14, L-1011-385-1-15, and L-1011-385-3 series airplanes,
certificated in any category; having serial numbers (S/N) 193A
through 193Y inclusive and 293A through 293F inclusive: -1002
through -1250 inclusive.
Unsafe Condition
(d) This AD results from a report of electrical arcing of the
essential bus feeder cables behind hinged circuit breaker panel CB3
P-K. We are issuing this AD to prevent arcing of essential bus
feeder cables due to improper installation of the harness C112 clamp
assembly, which could result in loss of electrical systems and smoke
and/or fire behind the CB3 P-K hinged circuit breaker panel in the
flight compartment.
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.
Detailed Inspection of the C112 Harness Clamp Assembly
(f) Within 90 days after the effective date of this AD: Do the
actions in paragraphs (f)(1) and (f)(2) of this AD by accomplishing
all the actions specified in the Accomplishment Instructions of
Lockheed L-1011 Service Bulletin 093-24-142, dated November 16,
2005. Do all applicable corrective actions before further flight.
(1) Perform a one-time detailed inspection of the C112 harness
clamp assembly to find incorrectly installed harness clamps, and do
all applicable corrective actions.
(2) Perform a one-time detailed inspection of the C112 and C162
harness assemblies to find evidence of chafing, arcing, or
deterioration, and do all applicable corrective actions.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
Alternative Methods of Compliance (AMOCs)
(g)(1) The Manager, Atlanta Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
Issued in Renton, Washington, on August 2, 2006.
