Airworthiness Directive · Amendment 39-18052 · Engine fuel & control
Alpha Aviation Concept Limited Airplanes
This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, serial numbers 001 to 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 paint adherence defects inside the engine air intake box and cohesion defects inside the laminated ducting from the filter to the air intake box. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the actions in paragraphs (f)(1) through (f)(4) of this AD:
(1) Within the next 100 hours time-in-service (TIS) after January 28, 2015 (the effective date of this AD) and repetitively thereafter every 100 hours TIS, inspect any painted engine air intake box (including the deflection flap) and the air intake ducting (including the area downstream of the filter) for paint adherence defects such as peeling, blistering, or bubbling following Alpha Aviation Service Bulletin (SB) No. AA-SB-71-007, Revision 0, dated August 2014.
(2) If any defects are found during the inspection required in paragraph (f)(1) of this AD, before further flight, replace the affected parts with airworthy parts following Alpha Aviation Service Bulletin No. AA-SB-71-007, Revision 0, dated August 2014.
(3) As of January 28, 2015 (the effective date of this AD), do not install a painted engine air intake box or a repaired engine air duct on any affected airplane.
(4) The replacement of defective parts is not a terminating action to the repetitive inspection of painted engine intake components required in paragraph (f)(1) of this AD.
