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.

Narrative: on February 11, 1998, at approximately 1615 MST, a big sky airlines SA-227, flight 1204, being operated as a domestic airline under FAR part 121, was cleared for takeoff on runway 29 at Missoula, Montana airport. During the takeoff roll, the fo (first officer) who was flying lost directional control. The fo relinquished the controls to the captain who was unable to regain control prior to the aircraft running off the runway approximately 1,000' from the start of the roll. The 4 blades on both propellers were bent when they struck a small snow berm along the runway edge. There was no other damage to the aircraft, and there were no injuries. This incident was caused by the right propeller being left on the locks (flat blade position); therefore, there was no thrust developed by the right engine. Contributing factor were failure of the flight crew to insure torque rise on both engines prior to the start of the takeoff roll, and then failure to abort the takeoff in a timely manner. Both pilots were given additional ground and flight training in aborted takeoff procedures by big sky airlines. INM05980009
