## 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:

It has been found cases in which the drain mast of the water and waste system does not meet the SFAR-88 (Special Federal Aviation Regulation No. 88) requirements. In case of fuel leakage or fuel vapor release, the proximity of this mast with the fuel tank may cause fuel ignition, leading to a possible tank explosion.

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