## 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:

It has been found the possibility of free-play between the mass balance weight and the elevator structure. This condition if not corrected could lead to elevator flutter and possible loss of airplane control.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
