NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The airplane stalled and impacted terrain during a soft-field takeoff. The student pilot was practicing a soft-field takeoff in preparation of his private pilot check ride. The student conducted the soft-field takeoff with the airplane established in a nose high pitch attitude. The student failed to reduce the wing's angle of attack and the airplane very quickly rose above ground effect. The certificated flight instructor (CFI) said that the student was a little slow in lowering the nose of the airplane to gain airspeed, but he (the CFI) delayed taking corrective action since the student's check ride was coming up and he wanted to see the student take action on his own. The student informed the CFI that it felt as though the right wing wanted to drop. The CFI took control of the airplane, lowered the nose and applied left aileron, but it was too late. The left wing dropped and the airplane descended to ground impact.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the student pilot's improper soft-field takeoff technique and failure to obtain and maintain an adequate airspeed, which resulted in a stall mush. The certificated flight instructor's inadequate supervision of the maneuver was also causal. Full narrative available
