Applicability: Lockheed Model L-1011-385-1, L-1011-385-1-14, L-1011-385-1-15, and L-1011-385-3 series airplanes, as listed in Lockheed TriStar L-1011 Service Bulletin 093-49-062, dated September 19, 1988, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To prevent a fire from arcing due to loose APU starter ground cables falling off the ground studs and onto the APU fuel shutoff valves, accomplish the following:

A. Within 6 months after the effective date of this airworthiness directive (AD), inspect the APU starter ground stud/bracket for proper installation and proper ground stud torque, in accordance with the Accomplishment Instructions of Lockheed TriStar Service Bulletin 093-49- 062, dated September 19, 1988. Any discrepancies identified must be corrected prior to further flight, in accordance with the service bulletin.

B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Lockheed Aeronautical Systems Company, P.O. Box 551, Burbank, California 91520, Attention: Commercial Order Administration, Dept. 65-33, Unit 20, Plant A-1. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Los Angeles Aircraft Certification Office, 3229 East Spring Street, Long Beach, California.

This amendment (39-6303, AD 89-18-11) becomes effective on September 25, 1989.
