From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Enigne quit on low level seismic survey flight. Rotor decay on autorotation. Water in fuel and at source. (-23) during cruise flight for a oil company survey the engine quite suddenly at an altitude of about 150 feet. The pilot did a 180 autorotate into the wind landing. The landing was very hard, the aircraft was substantially damaged. There were no injuries to the pilot or pax. On scene investigation revealed a substantial amount of water and other contamination in the fuel strainer. Investigation into the fueling procedure revealed the fuel storage tank at the remote site was contaminated with water and dirt. The filter used on the tank was improperly installed and the tank was located so the drain was above the lowest part of the tank.
