## 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:

Service experience has shown that heavy MLG (main landing gear) shimmy vibration can occur due to faulty/empty dampers or due to excessive free play in the T/L (torque link) apex joint. In several cases this shimmy vibration resulted in a MLG main fitting failure * * * finally resulting in a collapse of the MLG causing extensive damage to the wingtip, aileron and flaps. * * *

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