What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Apparently, during the briefing by the instructor on approach, the pilot thought he was to make a full stop landing but the instructor had intended for him to make a touch & go. During the landing roll the instructor asked the pilot if he was making a touch & go which the pilot responded by applying "takeoff power", but neither pilot remembered the carburetor heat. Subsequently the instructor decided to take the controls as they were approaching the end of the short runway. After becoming airborne the instructor realized they were not climbing normally and noticed they had full flaps. He retracted the flaps normally but with the loss of lift the airplane settled beyond the end of the runway and contacted soft sandy soil which caused the airplane to flip over onto its back and come to a stop.
