Applicability: Boeing 747 series aircraft; as listed in Boeing Alert Service Bulletin 747-27A2373 dated 24 June 1999.

Requirement: Action in accordance with the technical requirements of FAA AD 2001-22-13 Amdt 39-12492.

Background: The FAA requires replacement of the rudder pedal fasteners for both the captain’s and the first officer’s pedal assemblies with new, improved fasteners. This action is required to prevent loss of rudder control due to improperly torqued fasteners that connect the pushrod to the rudder pedal assembly, which could result in loss of controllability of the aircraft.
