The pilot and a friend flew in the friend’s airplane to pick up the Temco GC 1B after recent repairs were completed due to a previous ground loop in 2016.
The pilot’s friend and the mechanic observed the airplane during the takeoff. It accelerated straight and normal and flew “cleanly” off the turf runway in Hartsville, Indiana.
Shortly after rotation, the airplane rolled left until it hit trees in a near inverted attitude adjacent to the runway. The pilot died in the crash.
The mechanic stated he thought the airplane experienced a departure stall during the takeoff.
A post-accident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
The witness observations are consistent with the pilot’s loss of control after exceeding the airplane’s critical angle of attack during takeoff, which resulted in a power-on, aerodynamic departure stall.
Probable cause: The pilot’s loss of control after exceeding the airplane’s critical angle of attack during takeoff, which resulted in an aerodynamic stall.
