To eliminate a potential fire ignition source in the main cabin above the overhead stowage compartment area, accomplish the following:

A. Visually inspect the left and right overhead stowage compartment rail assemblies in the vicinity of each electrical bonding strap for evidence of arcing, burning, or chafing to electrical wiring. If damage is found, prior to further flight, repair the electrical wires in accordance with McDonnell Douglas MD-80 Maintenance Manual, Chapters 20-50-01 and 20-50-02.

B. Modify the electrical bonding strap installation of the left and right overhead stowage compartment rail assemblies in accordance with the Accomplishment Instructions of McDonnell Douglas MD-80 Alert Service Bulletin A25-309, dated October 30, 1989.

C. 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, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Avionics Inspector (PAI), who will either concur or comment and then send it to the Manager, Los Angeles Aircraft Certification Office.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.
