What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During an instructional flight the CFI had the student perform a stop and go landing. After landing/stopping the instructor told the student to take off. The flaps were still in the full down position. After rotation the instructor noted that the aircraft was in a flat/or slightly nose down attitude and realized the flaps were in the full down position. The instructor responed by retracting all the flaps at once. The aircraft lost lift and stuck the ground hard and bounced back into the air. The student continued the climb out and returned to home base. The student and instructor did not notice any issues during the return flight. At home base after engine shut down the instructor noticed that the left propeller tips' were curled. Aircraft received minor damage when the left propeller struck the ground.
