Unsafe Condition
After implementation of Dassault Aviation SB F2000-133 and F2000-166, a risk of engine cowlings separation from the airplane still exists, which 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.
