Probable cause
the pilot's failure to maintain an adequate airspeed and main rotor rpm during the landing approach as prescribed in the hydraulic pump failure emergency procedures found in the rotorcraft flight manual, thus resulting in a loss of control of the aircraft and the subsequent crash. Contributing to the accident was the failure of the hydraulic pump due to excessive coupling spline wear which was caused by the application of insufficient lubrication by the operator's maintenance personnel during pump installation and the improper manufacturing of the couple sleeve.
