Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all Iniziative Industriali Italiane S.p.A. (3I) Models Sky Arrow 650 TC and 650 TCN airplanes. This proposed AD would require you to repetitively inspect the engine mount for cracks and modify or replace the engine mount if cracks are found. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this proposed AD are intended to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.
