This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators used data provided by various sources and may have traveled in support of this investigation to prepare this aircraft incident report.

On January 7, 2016, about 1100 Alaska standard time, N395CE, a Robinson R44 II helicopter, sustained a total loss of engine power just prior to departure at the Anchorage International Airport, Anchorage, Alaska. The private pilot, who was the helicopter owner, and his flight instructor were not injured. The helicopter sustained no damage as a result of the incident. The helicopter was registered to and operated by Airglas Inc., under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan had been filed. 

During an on-scene interview with the National Transportation Safety Board (NTSB) Investigator-in-Charge (IIC) on January 7, 2016, the flight instructor reported that the purpose of the flight was to do a postmaintenance check flight after servicing and overhaul of the helicopter's fuel injection servo assembly. The instructor stated that after an extensive preflight inspection was completed, the helicopter was moved outside of the hangar. The helicopter's engine was started and allowed to warm up for about 10 minutes, and all ground run-up checks were satisfactory. He said that while operating at 100 percent rotor rpm and while raising the collective to begin the takeoff, the engine abruptly lost all power. 

The helicopter was equipped with a fuel injected, Lycoming IO-540 series engine. 

A postincident inspection of the fuel servo assembly revealed a white, greasy substance within the body of the servo assembly. A detailed examination of the fuel servo assembly is pending. 

The closest weather reporting facility is Anchorage International Airport. About 7 minutes before the incident, at 1953, an aviation routine weather report (METAR) at Anchorage, Alaska, reported in part, wind 010 degrees at 6 knots; visibility, 10 statute miles; few clouds at 6500 feet; temperature, 19 degrees F; dew point 16 degrees F; altimeter, 29.87 inHG.
