REGULATORY TEXT:  
82-03-04 R1 LOCKHEED-CALIFORNIA COMPANY: Amendment 39-4310 as amended by Amendment 39-4810. Applies to Lockheed Model L-1011-385 series airplanes, prior to Serial No. 1239, certificated in all categories. Compliance required as indicated, unless previously accomplished.

A. To detect leakage of flammable fluids in areas from which fluids or vapors could reach the auxiliary power unit exhaust shroud, accomplish the following:

1. Within 400 hours time in service from the effective date of this AD, and at repetitive intervals not to exceed 400 hours time in service thereafter, perform leak tests and visual inspections as specified in the Accomplishment Instructions of Lockheed Service Bulletin 093-49- 058 dated July 31, 1981, or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA Northwest Mountain Region.

2. If fuel or hydraulic fluid leakage is detected, repair or replace defective parts or components with serviceable units before further flight.

3. Upon request of an operator, an FAA maintenance inspector, subject to prior approval by the Manager, Los Angeles Aircraft Certification Office, FAA Northwest Mountain Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of that operator if the request contains substantiating data to justify the change for that operator.

B. To reduce the APU exhaust shroud skin temperature to a safe level, within 5000 flight hours or two (2) calendar years after the effective date of this amendment, whichever occurs first, install the APU Exhaust Duct and Shroud Insulation as specified in Part II, Accomplishment Instructions of Lockheed L-1011 Service Bulletin 093-49-058, Revision 3, dated October 28, 1982, or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. This action terminates the requirements for repetitive inspections required by paragraph A., above.

C. Alternate means of compliance with this AD, which provide an equivalent level of safety, may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA Northwest Mountain Region.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections required by this AD.

All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to: Lockheed-California Company, P.O. Box 551, Burbank, California 91520, Attention: Commercial Support Contracts, Dept. 63-11, U-33, B-1.
