The pilot, who was the owner of the tail-wheel-equipped airplane, was on an instructional flight to obtain a tailwheel endorsement. The pilot reported that the airplane experienced a sudden gust of wind just after liftoff and that he overcorrected, which caused the airplane to stall and settle back onto the runway. The flight instructor reported that the pilot abruptly pulled back on the control stick when the airplane accelerated to 50 to 55 mph during the takeoff roll. The airplane climbed about 5 feet above the ground and stalled. He assumed control of the airplane; however, it departed the left side of the runway and sustained substantial damage to the firewall and fuselage before it came to rest. After the accident, both pilots reported that the airplane did not experience any mechanical malfunctions or failures that would have precluded normal operation. The pilot reported 372 hours of total flight experience, which included 12 hours in the accident airplane during the 30 days preceding the accident. He further reported that the airplane's takeoff speed should have been 65 mph. The flight instructor had no previous flight experience in the airplane make and model. If he had experience in the airplane make and model, he would have been more familiar with its flying characteristics and been able to anticipate and correct the problem earlier.
