Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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: The results of full scale fatigue tests being conducted by the manufacturer have shown the need for inspection of critical fastener holes in the stub wing upper front spar cap, near the wing strut attachment. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
