Cessna 400 Series Aeroplanes
| AD/CESSNA 400/117 | Powerplant Electrical Wiring | 10/2008 |
|---|
| Applicability: | Model 441 aeroplanes, Serial Numbers 441-0001 through 441-0109. |
|---|---|
| Requirement: | 1. Check the aircraft records to determine if Cessna Propjet Service Information Letter (SIL) PJ79-27 dated 30 July 1979 or Revision 1 dated 13 September 1979 has been complied with. |
| 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 may indicate compliance with United States Federal Aviation Administration (FAA) AD 79-19-12 Amdt 39-3574, this is considered acceptable for compliance with this Directive. | |
| 2. If the Requirement 1 determination does not indicate compliance with SILPJ79-27 or Revision 1, rewire the engine control wiring in accordance with the instructions provided by SIL PJ79-27 Revision 1. | |
| Note 2: FAA AD 79-19-12 Amdt 39-3574 refers. | |
| Compliance: | For Requirement 1 - At the next scheduled maintenance but no later than 25 September 2009. |
| For Requirement 2 - Before further flight after the Requirement 1 inspection. | |
| This Airworthiness Directive becomes effective on 25 September 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 AD79-19-12. The FAA AD was originally issued to preclude an unplanned engine stoppage. |
| Whilst CASA acknowledges that there have been no incidents of a similar nature reported in Australia and that 14 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 serial numbers of affected aircraft in Australia, the compliance in this Directive is extended from that in the FAA AD of ‘Prior to the next flight’ to ‘At the next scheduled maintenance but no later than 25 September 2009’. |
