Microturbo SA Saphir 2 Model 016 Auxiliary Power Units
This AD applies to Microturbo SA Saphir 2 model 016 auxiliary power units (APUs) on which the exhaust thermal insulation has been replaced since January 1, 1995. These APUs are installed on, but not limited to, Dassault Falcon 20 airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above, on which the exhaust thermal insulation has been replaced since January 1, 1995. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 10 APU operating hours from the effective date of this AD, visually inspect the exhaust thermal insulation for signs of deterioration. Repeat the inspection at intervals not exceeding 10 operating APU hours.
(2) If deterioration is detected, replace the exhaust thermal insulation before operating the APU again. Use paragraphs 2.A. through 2.C.(4)(b) of Microturbo SA Alert Service Bulletin No. 49-11A76, Revision 1, dated September 6, 2007, to do the replacement.
(3) As mandatory terminating action to the repetitive visual inspections required by this AD, replace the exhaust thermal insulation within 50 APU operating hours from the effective date of this AD. Use paragraphs 2.A. through 2.C.(4)(b) of Microturbo SA Alert Service Bulletin No. 49-11A76, Revision 1, dated September 6, 2007, to do the replacement.
