What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot's reported all proper indications for engine power on takeoff roll and initial climb. Then, the aircraft failed to climb. Airport video shows what appears to be a normal takeoff roll and initial climb which then did not exceed ATC tower height. The tower offered any runway option. Once turning back toward the center of the airport the CFI banked in excess of 30 degrees resulting in an excessive sink rate which she did not halt prior to completing the turn, nor impacting the turf north of runway 10.
