COMPLIANCE: Required as indicated unless already accomplished. Reflect this AD compliance by an appropriate entry in the aircraft maintenance records.

A) Prior to next flight, clean interior of (MLG) shock strut trunnion and measure inside diameter of trunnion from aft side of gear using an internal micrometer. (Ref. Fig. 1 Sabreliner Service Bulletin 81-4, dated June 11, 1981.)

1. If measurement is 2.948 inches or less, return the airplane to service with an appropriate entry in the aircraft maintenance record.

2. If the measurement exceeds 2.948 inches, either replace the outer cylinder with an airworthy part (P/N 1127L001-3, -4, -5, or -6) and return the aircraft to service with an appropriate entry in the aircraft maintenance record, or remove the airplane from service and contact the FAA Aircraft Certification Program Office at telephone (316) 942-4219.

B) A special flight permit, in accordance with Federal Aviation Regulation (FAR) 21.197 for a flight by the most direct route to a base where maintenance can be performed, is authorized provided a dye penetrant check of the shaded area of the main landing gear shock strut outer cylinder as shown on Figure 1 of Sabreliner Service Bulletin No. 81-4, dated June 11, 1981, is conducted and no cracks are found. If cracks are found, a ferry flight will not be authorized unless the defective outer cylinder is replaced with an airworthy part (P/N 1127L001-3, -4, -5, or -6). The airplane shall be limited to a maximum gross weight of 20,500 pounds and a landing weight of 17,500 pounds for this special flight.
