Robinson Helicopter R22 BETA accident near Green River, Utah, April 6, 2014

On April 6, 2014 at about 6:15 pm local time, a 1996 Robinson Helicopter R22 BETA, registered N13HG, was substantially damaged in an accident during maneuvering (low-alt flying) near Green River, Utah. It was a personal flight under general aviation rules (Part 91). 2 people were killed. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

A loss of engine power due to fuel contamination while maneuvering at a low altitude and the pilot's inadequate preflight inspection, which failed to detect the contamination.

The NTSB's narrative final · quoted from the NTSB record

The pilot's family reported that the purpose of the flight was to look for shed elk antlers. When the helicopter did not return, a search was initiated. The wreckage was located the following day on the side of a gully in rough terrain. Onsite wreckage documentation revealed that the main rotor blades did not show evidence of rotation at the time of ground contact, and the rotating components of the airframe exhibited little damage. The gascolator container was stained an orange/brown color at the bottom and along the sides. Fluid drained from the gascolator was colorless but murky and had a faint smell of gasoline. A water/alcohol-indicating paste test revealed water contamination in the sample. If the pilot had drained fuel from the helicopter's fuel tank or gascolator before the flight, he would most likely have discovered the contamination. Other than the contaminated fuel, postaccident examination of the airframe and engine revealed no evidence of any anomalies that would have precluded normal operation of the helicopter. The pilot kept aviation fuel in a barrel on his property, and he would pump the fuel into 5-gallon plastic cans, which he used to fuel the helicopter. Testing of the fluid in some of the cans revealed significant water contamination. One of the cans contained a mixture of about 50 percent aviation fuel and 50 percent water, and another contained a mixture of about 85 percent aviation fuel and 15 percent water. The lack of damage to the main rotor blades and the rotating components of the airframe indicate that it is likely that the engine experienced a loss of power due to water contamination of the fuel. In order to spot antlers, the pilot was likely maneuvering at a low altitude; therefore, he had little time to react to a loss of engine power or locate a suitable landing site in the rough terrain.
