## 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) issued 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:

There are four ECS (environmental control system) grilles located in the flight deck side consoles. There have been occurrences where a grille has become detached during flight. There is a risk that a loose grille could foul the rudder pedals and interfere with rudder/brake control resulting in an unsafe condition.

The unsafe condition is a rudder pedal restriction or jam, which could result in reduced controllability of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
