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.

(.19) On July 23, 2002, about 1515 Alaska daylight time, a high skid-equipped mbb BO-105 helicopter, N491HL, sustained substantial damage during landing in a remote area, about 70 miles south-southeast of Deadhorse, Alaska. The helicopter was being operated as a visual flight rules (VFR) domestic on-demand passenger flight under title 14, CFR part 135, when the accident occurred. The helicopter was operated by air logistics of Alaska inc., fairbanks, Alaska. The commercial certificated pilot, and the sole passenger, were not injured. Visual meteorological conditions prevailed. A VFR flight plan was filed. During a telephone conversation with the national transportation safety board (NTSB) investigator-in-charge (iic), on July 24, the director of operations for the operator reported the pilot departed a survey camp area known as happy valley, located about 20 miles south of Deadhorse along the sagavanirktok river, on a flight to survey potential exploration sites. The director of operations said the pilot told him that he was flying about 70 feet above the ground at 50 knots. The pilot then began a descending left turn to land. The pilot indicated that the helicopter developed a high rate of descent. He applied collective pitch and power, but the rate of descent increased. The right landing gear skid contacted the ground, and the helicopter rolled onto its right side. The pilot told the director of operations that the wind conditions were about 3 knots from the east. (-23) while manuevering at at low altitude in an attempt to land at a remote site the pilot lost control of the aircraft and landed hard, followed by an aircraft rollover. privacy data omitted
