## 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:

* * * [S]ome aircraft could have experienced wing overpressure consecutive to the latent failure of both [pressure relief] valve units. Overpressure although not sufficient to cause static damages could have impaired the fatigue damage tolerance of the wing structure. * * *

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