Eurocopter AS350B3e Squirrel, G-ECUK

Summary:

The pilot lost yaw control of the helicopter as it approached the final stage of a decelerating transition to a hover. Examination of the helicopter established that hydraulic fluid leaked from two unions securing hydraulic pipes to the tail rotor hydraulic servo. The leak depleted the hydraulic contents to the extent that a loss of system pressure occurred.
