                    421C
Requirement:       1. Inspect fuel flow transducer Cessna part number (P/N) 9910395-9 (Aerosonics Corp P/N 33184-2) on each engine to determine the serial number.
                   2. If the P/N 9910395-9 transducer has a serial number included in the block 2364 through 2930, replace the transducer with a transducer whose serial number is not included in that block.
                Note 1:  The requirements of this Directive were most likely accomplished prior to the aircraft's arrival in Australia and the aircraft's maintenance records would indicate compliance with FAA AD 80-13-14, this is considered acceptable for compliance with this Directive.
                Note 2:  FAA AD 80-13-14 Amdt 39-3844 refers.
Compliance:     For Requirement 1 - At the next scheduled maintenance but no later than 8 May 2009.
                For Requirement 2 - Before further flight after the Requirement 1 inspection.
                This Airworthiness Directive becomes effective on 8 May 2008.
Background:     This Directive follows an internal review of Australian Airworthiness Directives (AD) which indicated an Australian AD was not issued in response to FAA AD
                80-13-14.  The FAA AD was originally issued to detect and replace possible defective fuel flow transducers which may cause fuel leaks in the engine compartment.

   Whilst CASA acknowledges that there have been no incidents of a similar nature reported in Australia and that only two of the affected aeroplanes are currently on the Australian register, CASA is required to publish State of design ADs which may affect Australian aircraft.  Consequently, given the time since the FAA AD was made and the limited number of affected serial numbers of affected aircraft in Australia, the compliance in this Directive is extended from that in the FAA AD of 'Before further flight' to 'At the next scheduled maintenance but no later than 8 May
