The pilot-receiving-instruction's excessive pitch control during takeoff, which resulted in an aerodynamic stall shortly after liftoff and the subsequent loss of control. Contributing to the accident was the flight crew's decision to have the flight instructor separately control the throttle while the pilot-receiving-instruction manipulated the flight controls, which resulted in inadequate coordination between the flight crew during the attempted stall recovery.

The inadequate in-flight planning/decision which resulted in fuel exhaustion and the loss of engine power. Contributing factors were the muddy terrain and the vegetation.
