Airworthiness Directives; Lockheed Model L-1011 Series Airplanes, 45447-45449 [E6-12948]

Download as PDF Federal Register / Vol. 71, No. 153 / Wednesday, August 9, 2006 / Proposed Rules 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. Executive Order 12988 This proposed rule has been reviewed under Executive Order 12988, Civil Justice Reform. If this proposed rule is adopted: (1) All State and local laws and regulations that are inconsistent with this rule will be preempted; (2) no retroactive effect will be given to this rule; and (3) administrative proceedings will not be required before parties may file suit in court challenging this rule. Paperwork Reduction Act This proposed rule contains no new information collection or recordkeeping requirements under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

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.

Comments will be available in the AD docket shortly after the Docket Management System receives them. 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. ESTIMATED COSTS Action jlentini on PROD1PC65 with PROPOSAL Inspection of clamp assembly .................

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. 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.

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

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.
