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:
Several cases of cracks on the main landing gear (MLG) door hinge fitting and MLG door actuator fitting on the keel beam were reported.
Such failure could lead to the loss [of] the MLG door and could cause damage to the aircraft and/or hazard to persons or property on the ground.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
