Applicability: All Model BAC 1-11 200 and 400 series airplanes, on which British Aerospace (BAe) main landing gear support structure Modification PM3070 is installed and Modification PM5928 has not been installed, certificated in any category. Compliance: Required as indicated, unless previously accomplished. To prevent collapse of a main landing gear, accomplish the following: A. Perform initial and repetitive ultrasonic and eddy current inspections of the main landing gear support beams at initial times and repetitive intervals shown in Table I of this AD using procedures in BAe Alert Service Bulletin 57-A-PM6000, Issue 2, dated February 17, 1988. TABLE I Airplane Identification Modification PM6000 Accomplishment Status Initial Inspection Compliance Time Repetitive Compliance Time Interval After Initial Inspection Serial Numbers up to and including 402 Not Accomplished Whichever occurs later: -within 300 landings after July 30, 1987, (the effective date of AD 87-13-03, Amendment 39-5654); or -within 3 years since installation of new left and right main support beams. Ultrasonic inspection: at intervals not to exceed 12 months. Eddy current inspections: at intervals not to exceed 36 months.

Ultrasonic inspections: at intervals not to exceed 12 months. Eddy current inspections: at intervals not to exceed 36 months. For all A/P's on which Mod. PM6000 is accomplished prior to assembly of main support beam into wing Accomplished Whichever occurs later: -within 8 years since new; or -within 8 years since new right and left main support beams are installed. Ultrasonic inspections: at intervals not to exceed 2 years. For all A/P's on which Mod. PM6000 is accomplished after assembly of main support beam into wing. Accomplished Within 2 years after installation of Modification PM6000 Ultrasonic inspections: at intervals not to exceed 2 years B. Cracks in the main landing gear main support beam must be repaired, prior to further flight, in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. C. Installation of main support beam, part number EDO3-5007/8 (Modification PM5928) constitutes terminating action for the requirements of this AD. D. 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, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who may add any comments and then send it to the Manager, Standardization Branch, ANM-113. E. 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 the modifications required by 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 British Aerospace PLC, Librarian for Service Bulletins, P.O.
