## 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) issued 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 deficiency in compliance with 14 CFR 23.967(d). There have been instances indicating that production aircraft may not have a metal barrier between the cabin and the fuel tank bay. Lack of a barrier could allow flammable fuel vapors to enter the cabin. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
