Visual meteorological weather conditions existed at the time of the accident. The flight departed Tampa International Airport in Tampa Florida, at 2245. Ten minutes into the flight, the pilot noticed a loss of engine oil pressure and a high engine oil temperature. The engine lost power, and the pilot entered an autorotation for a forced landing. During the autorotation the helicopter collided with high tension wires and fell to the ground. The examination of the helicopter disclosed that the engine oil pressure screen housing was loose. The oil pressure screen housing hardware was still in place, but absent of torque. The Director of Aircraft Maintenance for the City Of Tampa Police Department stated that, on July 5, 1996, a 50 hour inspection had been completed on the accident helicopter which included an oil change and the removal of the oil pressure screen housing for an inspection.
