Airworthiness Directives; McDonnell Douglas Model DC-8-70 Series Airplanes

This amendment supersedes an existing airworthiness directive (AD), applicable to all McDonnell Douglas Model DC-8-70 series airplanes, that currently requires repetitive inspections and repair or replacement, if necessary, of the generator power feeder cables, supporting brackets, and clamps at all the engine pylons. This amendment requires accomplishment of a terminating action for the repetitive inspections. This amendment also requires replacement of the support clamps of the generator power feeder cable on engine nacelles/ pylons 1, 2, 3, and 4 with new support clamps. This amendment is prompted by the FAA's determination that further rulemaking is necessary. The actions specified by this AD are intended to prevent a fire on the ground if a fuel leak exists in an engine pylon.
