Accident Overview
A helicopter operating from an offshore platform in the Gulf of Mexico suffered a power loss immediately after takeoff. The pilot held collective pitch to clear the rig, then deployed floats and initiated an autorotation to the water. Although the autorotation was successful, the aircraft was struck by a 5-foot wave and rolled over.
Occupant Actions
Both occupants exited the aircraft without difficulty. The passenger swam to the platform. The pilot inflated his life vest but was swept away by the current and swam ashore after 14 hours.
Investigation Findings
Examination revealed that the compressor discharge pressure (PC) line was disconnected from the back of the engine fuel control. According to the investigation, a leak or separation of the PC line would cause the fuel schedule to reduce engine speed to below flight idle. No recent maintenance had been performed on the fuel control or the line.
