Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
In service events have shown that, after implementation of Dassault Aviation SB F2000-133 and F2000-166, a risk of engine cowlings separation from the airplane still exists, and may cause potential damages to the engine itself and to the horizontal stabilizer. It is suspected that on-ground improper latching may lead to a radial deformation of engine cowlings in flight and to their eventual escape out of their locking devices. This situation may represent a hazard to the aircraft propulsive system and/or its structural integrity.
* * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
