COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

 Boeing 767 Series Aeroplanes

AD/B767/94 Thrust Management Computer Replacement 4/97
 Applicability: All 767 aircraft line positions 001 to 556, 558 to 587 and 589 to 615 inclusive. Requirement:               Replace the thrust management computer in accordance with Boeing Alert Service
            Bulletin 767-22A0097 dated 30 May 1996.

            Note: FAA AD 97-02-19 Amdt 39-9904 refers.

            Compliance: Unless previously carried out, replace the thrust management computer before 26 October 1998.

            This Airworthiness Directive becomes effective on 27 March 1997.

            Background: Boeing has had reported instances of uncommanded throttle advancement apparently due to a high impedance connection to the excitation phase of the servo motor. The actions mandated by this Airworthiness Directive are intended to prevent uncommanded runaway of the autothrottle during flight or ground operations as a result of the problems associated with the thrust management computer.
