in response to the United States Federal Aviation Administration (FAA) issuing AD 2008-10-02.

             Since then the FAA has received reports of 15 aeroplanes not previously affected by AD 2008-10-02 with a P/N 2013142-18 installed and the alternate static air source selector valve port was found obstructed by the P/N identification placard.

             The Civil Aviation Safety Authority (CASA) has no way of determining which aeroplanes have the remaining problem alternate static air source selector valve assemblies installed without having all of the affected aeroplanes and spares stock inspected.

             The FAA has been informed that all P/N 2013142-18 alternate static air source selector valves shipped from Cessna Parts Distribution between 1 January 1993, and 31 March 2008, may have port obstruction caused by the P/N identification placard.

             This condition, if not corrected, could result in the altimeter, airspeed, and vertical speed indicators displaying erroneous indications.  This could cause the pilot to react to incorrect flight information and possibly result in loss of control.
