## 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 landing gear emergency extension valves have been found seized * * *. This condition, if not corrected, could result in malfunctioning of the landing gear release during an operational emergency.

This malfunction could cause failure of the landing gear to extend and lock in the extended position, which could result in a gear up landing and reduced controllability of the airplane on the ground. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
