Cessna 320D N320KP accident near Fallon, Nevada

Probable cause

The pilot’s inadequate airspeed, which resulted in an aerodynamic stall.

NTSB analysis

Witnesses reported seeing the airplane approach the airport from the southwest and cross near mid-field to enter the left traffic pattern for landing. Witnesses observed the airplane make a right 270-degree turn to enter on the downwind and, after becoming established on the downwind, make a sharp left turn and descend out of sight near a point consistent with a turn to a close-in base leg. Witnesses then reported seeing a fireball erupt in the area of the accident site. On the downwind leg, at a radar-recorded ground speed of 93 to 106 knots, the airplane's indicated airspeed could have been between 71 and 81 knots, which is in the range of potential stall speeds. Ground scar and wreckage signatures were consistent with a nose-low and left-wing-low ground impact. The witness observations and the impact attitude could be consistent with a stall and loss of control. No anomalies or other conditions were found with either engine that would have precluded normal operation.
