Airworthiness Directive · Amendment 39-17208 · Power plant
Alpha Aviation Concept Limited Airplanes
This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, all serial numbers, 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 possible installation of non-conforming air filter elements that are not fitted with metallic mesh and could internally collapse resulting in disruption of the powerplant operation. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions following Alpha Aviation Service Bulletin AA-SB-71-006, dated May 2012:
(1) Within the next 30 days time-in-service (TIS) after November 9, 2012 (the effective date of this AD), inspect the air filter part number (P/N) 57.34.00.010 to determine if it has been fitted with a perforated metal liner.
(2) If, after the inspection required in paragraph (f)(1) of this AD, the air filter part number (P/N) 57.34.00.010 is found to include the perforated metal liner, no further action is required.
(3) If, after the inspection required in paragraph (f)(1) of this AD, the air filter is found to not contain the perforated metal liner, before further flight, replace the air filter with a new air filter P/N 57.34.00.010 that does contain the perforated metal liner.
(4) After November 9, 2012 (the effective date of this AD), do not install any air filter P/N 57.34.00.010 that does not have the perforated metal liner depicted in Alpha Aviation Service Bulletin AA-SB-71-006, dated May 2012.
