## Summary

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters, Inc. (previously Eurocopter France) Model AS355E, AS355F, AS355F1, and AS355F2 helicopters with a Fueltron flowmeter installed. This proposed AD would require removing each flowmeter, replacing the fuel system hoses, and disabling the electrical connections for the flowmeter installation. This proposed AD is prompted by a report of particle contamination creating an obstruction in a flowmeter which resulted in an uncontrolled flame-out of the engine. The proposed actions are intended to prevent obstruction of the fuel supply to the flowmeter, which could result in engine flame-out and subsequent loss of control of the helicopter.
