## Abstract

We are adopting a new airworthiness directive (AD) for the products listed above. This 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. We are issuing this AD to require actions to correct the unsafe condition on these products.
