AD 94-28886

Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Canadair Model CL-600-2B19 series airplanes, that currently requires a revision to the FAA-approved Airplane Flight Manual (AFM) to restrict altitude and airspeed operations of the airplane under certain conditions of hydraulic system failure. This amendment requires the removal of all elevator flutter dampers and requires a revision to the AFM that advises the flight crew of the need to perform daily checks to verify proper operation of the elevator control system. This amendment is prompted by reports that the installation of the stronger shear pins may jam or restrict movement of the elevator. The actions specified in this AD are intended to prevent failure of the lugs and/or pins, which may increase the likelihood of jamming or restricting movement of the elevator and the resultant adverse affect on the controllability of the airplane.
