What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot over rotated during a night takeoff, stalled and settled back hard on the left main gear and tail. One arm of the left main landing gear casting fractured and the tail cone was deformed and damaged. The pilot had loaded the aircraft to 100 pounds below gross weight, topping the left wing fuel tank and partially filling the right wing fuel tank to manage weight and balance. He knew he was heavy so he used a faster airspeed for rotation. When he made the rotation he put too much elevator input into the maneuver, plus the center of gravity (CG) was in the aft portion of the envelope. The pilot, 58 inches tall, had difficulty seeing over the instrument panel in the darkness and the vertical adjustment of the seat was inoperative, so the seat was in the full down position.
