Amateur-built MONI N983JV accident near Tulsa, Oklahoma

Probable cause

An aerodynamic stall/spin and loss of control for reasons that could not be determined based on the available information.

NTSB analysis

The student pilot was departing in the motorglider when the accident occurred. A witness stated that the glider used about 3/4 of the 2,580-ft-long runway to become airborne. As the glider climbed, it entered an aerodynamic stall and spin, and subsequently impacted terrain. Security camera footage showed the glider impact the ground in a near-vertical, nose-low attitude in a counterclockwise spin. The glider sustained substantial damage to the right wing and fuselage.

An examination of the glider did not reveal any anomalies that would have precluded normal operations. The glider’s maintenance history could not be determined. The glider had been deregistered about 8 years before the accident. The student pilot’s logbook was not located, and neither his total flight experience nor experience in the accident glider could be determined.

Although the circumstances of the accident are consistent with an aerodynamic stall/spin and loss of control, the reason for the loss of control could not be determined based on the available information.
