## 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:

Some operators have reported airframe vibration under specific flight conditions including gusts.

Investigations have revealed that under such conditions, vibrations may occur when the hinge moment of the elevator is close to zero, associated to elevator free-play. * * * * *

The unsafe condition is excessive vibration of the elevators, which could result in reduced structural integrity and reduced controllability of the airplane.
