## Summary

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B3 and EC130B4 helicopters. This proposed AD would require revising the Limitations section of the Rotorcraft flight Manual (RFM) to reduce the starter generator operating current to 180 amperes (amps) and installing a placard in the instrument panel indicating the revised limitation. This proposed AD is prompted by the determination that the manufacturer-installed Aircraft Parts Corporation (APC) starter generator has exceeded the shaft horse power extractions allowed for Turbomeca engines. The proposed actions are intended to prevent the engine surge margin being reduced, which can result in engine failure.
