Revises amendment 39-8185, AD 92- 06-05. Docket No. 91-NM-209-AD. Applicability: Model DH/BH/HS/BAe 125 series airplanes, except Model BAe 125-1000A series airplanes, certificated in any category. Compliance: Required as indicated, unless accomplished previously. To prevent reduced structural integrity of the fuselage and subsequent decompression of the airplane, accomplish the following: (a) Prior to the accumulation of 4,000 landings, or within 60 days after the effective date of this AD, whichever occurs later, accomplish the following in accordance with British Aerospace Service Bulletin 53-73, Revision 2, dated May 18, 1991: (1) Perform a visual inspection of the nose landing gear (NLG) bay left and right sidewalls to detect the presence of washers or spotface under nuts. (i) If no spotface is found, perform a visual inspection to detect damage to the web caused by nuts or washers. (ii) Blend out any damage found, excluding cracking, prior to further flight. (2) Perform either a dye penetrant or eddy current inspection to detect cracks on the NLG bay left and right sidewalls. If cracks are found, repair prior to further flight, in a manner approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. (b) An alternative method 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, Transport Airplane Directorate. The request shall be forwarded through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Standardization Branch, ANM-113. (c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The inspections shall be done in accordance with British Aerospace Service Bulletin 53- 73, Revision 2, dated May 18, 1991. This incorporation by reference was previously approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51 as of April 21, 1992 (57 FR 9170, March 17, 1992).
