AD FAA-2015-3956

We are superseding Airworthiness Directive (AD) 2008-09-01 for certain 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 a need to revise the maintenance program to include the revised airworthiness limitations for the internal wing structure and wing attachment inspections. We are issuing this AD to require actions to address the unsafe condition on these products.
