## 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:

A damaged wiring harness which caused the air conditioning system circuit breaker to trip and evidencing a local overheating has been found on an in-service aircraft.

The investigation revealed that the damage (chafed wires) found on the wiring harness resulted from an interference with the under- floor attachment fittings of the cabin partition net which was due to an incorrect routing of the harness while on the production line.

Such conditions could result in an electrical short and potential loss of several functions essential for the safety of flight.

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