Summary
We propose to adopt a new airworthiness directive (AD) for certain REIMS AVIATION S.A. Model F406 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 cracks found in the horizontal stabilizer rear attach structure and the vertical fin rear spar attach structure. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
