Summary
This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Airbus Model A300- 600 and A310 series airplanes, that currently requires revising the Airplane Flight Manual (AFM) to instruct the flightcrew to cross-check certain primary power setting parameters of the Thrust Control Computer (TCC) against tables of these values; and apply corrective action, if necessary. That AD also provides for optional terminating action for the AFM revisions. This proposed rule would require accomplishment of the previously optional terminating action. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent incorrect primary power setting parameters of the TCC, which could result in insufficient thrust being applied during takeoff.
