## 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 an obstruction at the cargo compartment fire extinguisher system drier metering unit (DME) inlet, affecting the system effectiveness and, consequently, making the fire extinguishing capability at those compartments inadequate should a fire erupt. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
