Narrative Report
On June 10, 2001 at 12:21 PM, Peoria – Santa Fe experienced a crash involving Mitsubishi MU-2 Marquise, operated by John M. White, with the event recorded near Cerrillos New Mexico.
The flight was categorized as private and the reported phase was flight at a plain, valley crash site.
2 people were known to be on board, 2 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 1, crew fatalities: 1, passengers on board: 1, passenger fatalities: 1, other fatalities: 0.
The listed crash cause is human factor. The pilot was maneuvering the airplane south of the airport preparing to make a VFR approach. Witnesses observed the airplane in a right spin. NTAP data showed the airplane to be well above stall speed before disappearing from radar. Examination of the radar data revealed that in 6 seconds, ground speed dropped 31 knots, from 200 knots to 169 knots, and altitude dropped 440 feet, from 11,760 feet to 11,320 feet (4,400 feet per minute). In the next 6 seconds, ground speed dropped another 31 knots, from 169 knots to 138 knots, and altitude dropped 1,020 feet, from 11,320 feet to 10,300 feet (10,200 feet per minute). According to the manufacturer, if the throttles were to be brought back into Beta (flat pitch) range, it is possible that one propeller could go into Beta an instant before the other propeller. If this were to happen, the airplane would instantly snap roll and enter a spiral. The pilot had received an estimated 4 hours of dual instruction in the airplane.
Aircraft reference details include registration N187AF, MSN 187, year of manufacture 1970.
Geospatial coordinates for this crash are approximately 35.4375°, -106.1262°.
