AD 2004-08-15 Amdt 39-13584 Correction refers.

            Compliance: For Requirement 1 - Remains unchanged as 'Within the next five hours time in service after the effective date of original issue of this Directive'.

            For Requirement 2 - Remains unchanged as 'Before further flight immediately following the Requirement 1 inspection'.

            For Requirement 3 - Remains unchanged as 'As of the effective date of the original issue of this Directive.

            This Amendment becomes effective on 5 August 2004.

            Background:  The United States Federal Aviation Administration (FAA) has advised that tests have shown that the TAWS8000 TAWS may cause altitude errors in other instruments.
            This Directive is intended to prevent the loading of the baro set potentiometer, which could result in an unacceptable altitude error. Such a condition could cause the pilot to make flight decisions that may put the aeroplane in an unsafe flight condition.

            The original issue of this Directive required the inspection of the TAWS installation and, if necessary, the removal of the TAWS if both the TAWS and any other device are connected to the same baro set potentiometer. The Directive also prohibited future installation of any TAWS8000 TAWS that incorporates hardware "Mod None", "Mod A" or "Mod B".

            This amendment introduces a revised Service Memo as an alternate method of compliance together with a note clarifying the status of TAWS8000 units with "Mod C" hardware incorporated.

            The original issue of this Airworthiness Directive became effective on 30 July 2003.
