Airworthiness Directive · Amendment 39-17073 · Engine oil
Alpha Aviation Concept Limited (Type Certificate Previously Held by Alpha Aviation Design Limited) Airplanes
This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, serial numbers 001 through 378, certificated in any category.
We are adopting a new airworthiness directive (AD) for Alpha Aviation Concept Limited Model R2160 Airplanes. 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 oil lines fitted to affected aircraft are not fire resistant. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) Within 50 hours time-in-service (TIS) after July 12, 2012 (the effective date of this AD), replace the oil hose lines (part number (P/N) 41-23-56-000, 53-11-10-000, 53-20-13-000, 53-20-14-000, 53-34-10-010, 53-18-02-030, 53-21-14-000, or 53-22-01-000) following Apex Aircraft Service Bulletin No. 020310, dated June 3, 2002, and replace the oil pressure transducer hose and associated hardware following Alpha Aviation Service Bulletin AA-SB-79-001, Revision 0, dated February 2012.
(2) As of July 12, 2012 (the effective date of this AD), do not install any oil hose lines with P/N 41-23-56-000, 53-11-10-000, 53-20-13-000, 53-20-14-000, 53-34-10-010, 53-18-02-030, 53-21-14-000, or 53-22-01-000 on the affected aircraft.
