## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Turbomeca Artouste II and Artouste III series turboshaft engines. This proposal would require installation of modification TU 24, TU 167 or TU 164, depending on the specific engine model. These modifications would prevent uncommanded partial closing or total closing of the electrical fuel cock, which would prevent uncommanded in-flight engine shutdown. From the effective date of this AD, and until the modifications are installed, this proposal would also limit the duration of the engine operating cycle. This proposal is prompted by reports of unexpected power loss during test flights. The actions specified by the proposed AD are intended to prevent unexpected power loss, which could result in an uncommanded in- flight engine shutdown, autorotation, and forced landing.
