EASA Proposes New Airworthiness Directive for Eurocopter France AS350B and AS355N Helicopters

Summary

The European Aviation Safety Agency (EASA) proposes a new airworthiness directive (AD) for Eurocopter France's AS350B and AS355N helicopters to address fatigue cracks in the tail rotor hub pitch change plate 'SNR' bearing. The proposed measure aims to prevent bearing seizure, loss of tail rotor effectiveness, and subsequent loss of helicopter control.
