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.

Helicopter struck a powerline transformer, crashed on approach to helipad, burned. (.4)after refueling, the pilot departed north from a helipad with an observer aboard. The helicopter overflew a 50 foot building located 141 feet from the pad. The helicopter started to shudder over the building and shuddered again when it crossed a powerline located 292 feet from the pad. The observer reported the helicopter did a right, flat turn. The helicopter impacted the top crossbeam of a powerline pole, then impacted the ground in a right skid down, nose low attitude. A fire erupted. The pilot was initially pinned in the wreckage, but the observer & a truck driver, who arrived at the scene, were able to extricate the pilot. Investigation revealed evidence of continuity in the flight controls and engine, but the magnetos were fire damaged & could not be tested. Performance calculations indicated that power required for a 50' hover out of ground effect (hoge) would have been 154 HP; power available should have been 173 HP. The local airport's (aviation routine weather report) METAR winds indicated 100 degrees at 7 knots. The win d stock at the helicopter pad was not functional. For takeoff, the pilot also had the option to depart the helipad on a heading of 140 degrees, or to depart on a heading of 320 degrees after back taxing about 150 feet for additional takeoff distance. The pilot received serious burns & head injuries. He was wearing a polyester based police uniform & no flight helmet or gloves. The observer was wearing a nomex flight suit and boots, but no helmet or gloves.
