Airworthiness Directive · Amendment 39-12545 · McDonnell Douglas Model DC-8 Series Airplanes
McDonnell Douglas Model DC-8 Series Airplanes
Model DC-8 series airplanes, serial numbers 45646 and 45928, and as listed in McDonnell Douglas DC-8 Alert Service Bulletin A27-275, Revision 1, dated February 3, 1992; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-8 series airplanes, that currently requires repetitive visual and eddy current inspections to detect cracking of the rudder pedals adjuster hub assembly, and replacement of the assembly with a new assembly, if necessary. This amendment requires accomplishment of a terminating action for the repetitive inspections. This amendment also adds airplanes to the applicability of the existing AD. This amendment is prompted by the FAA's determination that further rulemaking is necessary. The actions specified by this AD are intended to prevent loss of rudder pedals control and reduction of braking capability.
