## 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:

Abnormal manufacturing variations of the universal joints in combination with mechanical wear can lead to a joint failure and subsequent disconnection between selector and the fuel valve. This result in a loss of capability to select the fuel tank for supply. This condition might remain unrecognised by the pilot and can result in fuel starvation during flight and/or unavailability of emergency fuel shutoff.

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