Directive becomes effective on 6 September 2001.

           Background:  The manufacturer received reports of propeller overspeed events simultaneously affecting both engines when the power levers were inadvertently moved into the Beta range in flight. Investigation revealed that both circuit breakers of the Secondary Flight Idle Stop System (SFISS) were open. The additional maintenance requirements mandated by this Directive will enhance the reliability of the SFISS.

           This amendment to the Directive:

              * Revises the SFISS test requirements to require immediate rectification if the SFISS is found defective;

              * Adds a requirement for additional flight crew training to address inadvertent selection of Beta range in flight;

              * Makes reference to a new SFISS that provides terminating action for the test and training provisions in the AD; and

              * Requires reliability improvements to a certain version of the new SFISS.
