## 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:

development of the New Zealand produced Alpha 160A aircraft identified an issue with the fuel shut-off valve, where it may not be possible to switch the valve ON once the valve has been placed in the OFF position. This is due to friction in the shut-off system. The fuel shut-off valve, which is normally ON, is a safety feature to allow the pilot to stop fuel flow to the engine in an emergency situation such as a forced landing without power. The fuel shut-off control is guarded and requires a deliberate action by the pilot to operate. Not withstanding this, a hazardous situation is possible if the fuel shut-off valve is inadvertently switched OFFin flight and the pilot is not able to switch it back ON.

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