Navigation flight, pilot in traning. A loud bang was heard with severe vibrations. The pilot carried out an emergency landing (auto rotation), success.
The accident was caused by:
-The deep groove ball bearing in the engine pulley failed. The underlying cause was that it is delicate to inspect with certainty whether grease has penetrated into the bearing when applying lubrication.
Recommendation:
EASA is recommended to ensure that Hélicoptères Guimbal amends the procedure for the lubrication of bearings with part number HG61-0790 so that at inspections it is possible with certainty to determine that a sufficient quantity of grease has been injected into the ball bearing and at the correct position.
