Summary
This document proposes the supersedure of 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 action would require accomplishment of a terminating action for the repetitive inspections. This action also adds airplanes to the applicability of the existing AD. This proposal is prompted by the FAA's determination that further rulemaking is necessary. The actions specified by the proposed AD are intended to prevent loss of rudder pedals control and reduction of braking capability.
