COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES Cessna 208 Series Aeroplanes AD/CESSNA 208/1 Amdt 1 Fuel Selector Off Warning System 1/87 Applicability: All Cessna Caravan I models 208/208A, serial numbers 20800001 through 20800105. Requirement: Action in accordance with: 1. Cessna S.B. CAB 86-8. 2. Cessna S.B. CAB 86-26. Note: FAA AD 86-22-06 refers. Compliance: Unless already accomplished, prior to the issue of the next Maintenance Release after 28 February 1987. Background: 1. Accident investigations in the U.S.A. have revealed fuel starvation during take-off due to improper positioning of fuel tank selectors. Consequently a warning system has been designed which indicates to the pilot fuel tank selector position and fuel tank low level condition, and provides a more appropriate level of safety in respect of turbine engine fuel system design requirements. 2. This amendment adds S.B. CAB 86-26 to improve the integrity of the low fuel level warning system, by the addition of a lock washer and sealant to ensure transmitter nut retention.
