## Probable cause

an engine deceleration event due to a loose HMU fuel line fitting, which was a result of inadequate maintenance procedures in the 100/300-hour inspection.  Also causal was the flying pilot's and pilot-in-command's delayed recognition of the power loss, as well as, the flying pilot's failure to initiate an autorotation in a timely manner.  The pilot-in-command's failure to regain and maintain adequate main rotor rpm was also causal.  A contributing factor to the accident was the pilot-in-command's inadequate supervision and diverted attention due to his concentration on the flight officer observer duties.
