AS350B3 False NR Overspeed Indications
My work had multiple AS350B3 NR Overspeeds with no horn or VEMD indications until shutdown(Pilot confident of no overspeed!). The time on the VEMD is 00.0 Seconds with not other indications, any thoughts? The mechanics think it may be a cannon plag/contact issue; but has anyone had faults due to weather..ie: cold weather/precip?
