For airplane serial numbers as listed in BAe-125 Service Bulletin 53-63, dated February27, 1987: Prior to the accumulation of 7,500 flights, or within 6 months after the effective date of this AD, whichever occurs later, visually inspect the fuselage skin beneath the canopy blister for cracks in accordance with that service bulletin. Repair detected cracks prior to further flight in accordance with an FAA approved method. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Standardization Branch, ANM-113, 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.
