the replacement of existing EEC's is available in Honeywell Alert Service Bulletins TPE331-A76-0035 dated 23 July 2001, TPE331-A76-0036 dated 23 July 2001, and TPE331-A76-0037 dated 23 July 2001.

              When all EECs have been replaced in the aeroplane with serviceable EECs, the AFM TRs specified in Requirement 1 may be removed from the AFM.

            Note 2: FAA AD 2001-21-02 Amdt 39-12472 refers.

 Compliance: For Requirement 1 - Within 30 days after the effective date of this Directive.

            For Requirement 2 - Before 31 August 2003.

            This Airworthiness Directive becomes effective on 19 November 2001.

            Background: The United States Federal Aviation Administration received a report of an engine experiencing an uncommanded full power increase during an approach while both engine power levers were at the flight idle gate. There have been numerous incidents where these engines have experienced uncommanded engine flow increases during flight and ground operations.

            This Directive requires revision of the Emergency and Normal Procedures section of the applicable AFM until the existing EEC's are replaced. These actions are intended to minimize exposure to flight and ground operations that could lead to the loss of control of the airplane due to asymmetric thrust and an uncommanded torque increase.
