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.

(-23) On sept 7, 2008 at approx 1415 MDT, N26930 a Gulfstream AA-5A cheetah crashed while maneuvering through a left turn at slow speed in a canyon near baxster pass, 20 miles nw of Mack, CO. The two occupants on board were killed, the aircraft was destroyed. According to evidence found at the scene and reported witness statements the aircraft was performing pipeline patrol during the exit of a continued left turn (opposite the direction of flight) the aircraft stalled and crashed at a steep degree down angle. It was reported that the pilot was not familiar with the area of the pipeline, direction of route, and mountain flying. It was determined that the route of the flight following the pipe had been overshot missing the turn left, during the correction the pilot lost control. Weather was not a factor and no obvious mechanical problems with the aircraft were noted on site. Human factors could have played a major role, pilot had been involved in a previous accident 4 days prior to new Mexico, after working a 17 hour day in a company aircraft, and then flying a un-familiar route in co. underwood aerial patrol hired the PIC on September 2, 2008.
