## Summary

We propose to adopt a new airworthiness directive (AD) for Alpha Aviation Concept Limited Model R2160 Airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 proposed AD to require actions to address the unsafe condition on these products.
