## Summary

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:

A report has been received of stress corrosion cracking occurring in the wing lift strut lower clevis fitting, part number C2W-1097A.

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