Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-10, -20, -30, -40, and -50 series airplanes; Model DC-9-81, -82, -83, and -87 series airplanes; Model MD-88 airplanes; and C-9 airplanes; that currently requires repetitive inspections to detect cracking of the rudder pedal adjuster hub assembly, and replacement of the assembly, if necessary. That AD also provides for an optional terminating action for the repetitive inspections. This action would require accomplishment of a new terminating action for the repetitive inspections. This proposal is prompted by that FAA's determination that further rulemaking is necessary. The actions specified by the proposed AD are intended to prevent loss of rudder pedal control and reduction of braking capability.
