## 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:

During maintenance on a 328-100 aeroplane, a crack was found on a trim tab fitting assembly. The cause of the cracking was identified as stress corrosion.

This condition, if not corrected, could lead to in-flight failure of the tab fitting, possibly resulting in loss of control of the aeroplane.

* * * * *

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