original compliance of 'Effective 3 January 1996' remains unchanged.

           This amendment becomes effective on 18 June 1998.

               Background: The FAA has received reports of failure of the audio output of CAS-81 TCAS. This condition could result in the CAS-81 TCAS failing to perform its collision avoidance function.

               The original issue of this Directive required a revision to the Aircraft Flight Manual to provide the flightcrew with procedures to cycle power to the TCAS processor via the circuit breaker or power bus and to perform a TCAS functional test to verify proper operation of the TCAS.

               This Amendment amends the title of the Directive, identifies the serial number range of the effected equipment and introduces an optional terminating action, whereby the original flight manual amendment may be removed. It also introduces an alternative flight manual amendment, which may be used if the aeroplane manufacturer has substantiated 30º C as a maximum ambient temperature for the TCAS processor location.

               The original issue of this airworthiness directive became effective on 3 January 1996.
