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:
[E]scape slide system installation [was found with] * * * tie-down straps which are used for escape slide packing [having not been removed]. The non-removal of the tie-down straps does not allow the aircraft door to reach the fully open position and the consequent deployment of the escape slide system in a * * * emergency evacuation, affecting the occupying safety.
The unsafe condition is failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
