## 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:

In the door 2 area, the hat-racks are supplied with a basic wire harness which includes "Oxygen Masks'' activation. In case of a monument installation, the respective non-used hat- rack connections between monument and outer skin are put on stow. It was noticed in production, that the distance between the stowed wire harness and the monument could be too small. This condition, if not corrected, could lead to the short circuit of wires dedicated to oxygen, which, in case of emergency, could result in a large number of passenger oxygen masks not being supplied with oxygen, possibly causing personal injuries. * * * * *

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