## 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 indicates that as aircraft become older, they are more likely to exhibit indications of corrosion.

Additionally, the FAA has reviewed the service experience and finds this action to be necessary based upon that service experience. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
