## Summary

We are revising an earlier NPRM 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:

To prevent failure of the wing structure and assembly components due to undetected fatigue and corrosion * * *

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