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:
This Airworthiness Directive (AD) results from one report about imperfect locking on ground of the upper access door opening interior handle which has enabled its opening without actuating unlocking knob.
If not corrected an inadvertent action on the handle without actuating the unlocking knob could lead to a door opening.
Investigations identified the unsafe condition resulting from interference between the window trim panel and the handle locking mechanism.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
