Cessna 340 Series Aeroplanes AD/CESSNA 340/36 Deice System Electrical Power 6/2008

Applicability: Model 340A aeroplanes Serial Numbers 340A0901 through 340A0994 and 340A1002. Requirement: 1. Inspect the aeroplane maintenance records to determine if paragraph B of FAA AD 80-19-10 (wiring inspection and wiring change, in accordance with Cessna Multi-engine Customer Care Service Information Letter (SIL) ME80-31 dated 18 July 1980) was complied with prior to the aeroplane's arrival in Australia. If paragraph B of AD 80-19-10 was complied with no further action is necessary. 2. If compliance with paragraph B of AD 80-19-10 cannot be positively determined, perform the wiring inspection and carry out the wiring change, if required, in accordance with Cessna Multi-engine Customer Care SIL ME80-31. Note: FAA AD 80-19-10 Amdt 39-3922 refers. Compliance: For Requirement 1 and 2 - Prior to the issue of an Australian Certificate of Airworthiness. This Airworthiness Directive becomes effective on 5 June 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 80-19-10, as there were no aircraft in the affected serial number range in Australia at that time. The FAA AD was originally issued to prevent flight in adverse weather conditions without a means of supply of electrical power to the deice system. Whilst CASA acknowledges that currently there are no 340A model aeroplanes from the affected serial number range on the Australian register of aircraft, CASA is obliged to issue an AD reflecting the requirements of an AD issued by the State of Design, as an aeroplane from the affected serial number range may be imported into Australia at any time and that aeroplane may not be in compliance with FAA AD 80-19-10.
