ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 80-15-01 LOCKHEED-CALIFORNIA: Amendment 39-3840. Applies to Lockheed Model L- 1011-385 Series Airplanes certified in all categories. Compliance required within the next 300 hours' time in service after the effective date of this AD, unless already accomplished. To prevent a possible burst type failure of the landing gear alternate brake/alternate landing gear down accumulator, accomplish the following: (a) Unless previously accomplished within 2200 hours' time in service prior to the effective date of this AD, (1) Inspect all accumulators Lockheed P/N 672273-101 (Bendix P/N 3186608) and Lockheed P/N 672273-103 (Bendix P/N 3186608-2) in accordance with Lockheed Alert Service Bulletin 093-32-A121 dated November 11, 1976, or, (2) Replace accumulators with accumulators reworked per Lockheed Service Bulletin 093-32-121 dated October 17, 1977. (b) Accumulators which fail the inspection, prior to further flight operations, must be either: (1) Removed and replaced with an accumulator which has passed the inspection or, (2) Removed and replaced with an accumulator which has been reworked per (a)(2) above or, (3) Remove the affected accumulator and accomplish the following actions in accordance with Lockheed Alert Service Bulletin 093-32-A121, dated November 11, 1976. (i) Cap pneumatic and hydraulic lines. (ii) Install landing gear alternate brake/alternate landing gear down accumulator inoperative placard in cockpit; (iii) Incorporate FAA-approved Appendix 11 dated November 17, 1976, in the FAA-approved AFM, LR 25925. Appendix 11 provides special procedures for operation of the L-1011 with landing gear alternate brake/alternate landing gear down accumulator removed. (c) Accumulators which passed inspection per (a)(1) or which were used as a replacement accumulator per (b)(1) must be reinspected per (a)(1) every 2200 hours' time in service until replaced with accumulators reworked per (a)(2). (d) Equivalent inspections and/or modifications may be used when approved by the Chief, Aircraft Engineering Division, FAA Western Region. This supersedes Amendment 39-2783 (41 FR 53779), AD 76-25-01. This Amendment 39-3840 becomes effective July 17, 1980. FOOTER:
