To prevent loss of electrical power and eliminate a potential fire hazard, due to chafed cable looms, accomplish the following:

A. Perform a one-time inspection of the electrical cable looms above panel DA-E for cable chafing and adequate clearance from adjacent equipment, in accordance with British Aerospace Service Bulletin 24-270, dated March 20, 1989. If any cable is chafed or if clearance is insufficient, prior to further flight, repair in accordance with the service bulletin.

B. 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 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 airplanes to a base for the accomplishment of the requirements of this AD.
