What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot involved flew this aircraft over two hours earlier the day of the incident. He flew from 9A0 to gvl and back to 9A0. Later in the day he decided to do some patern work at 9A0. The pilot was landing, taxi to the opposite end of the runway and turned around to takeoff in the opposite direction as the wind was calm. Due to the mountainous nature of the environment, the pilot said that he always checked te magnetos and was leaning the aircraft for maximum power on each takeoff (all landings were full stop). On approximately the third takeoff (conducted on runway 15) the pilot completed his takeoff check, included leaning the aircraft and started the departure. When he was airborne and beyond the middle of the runway (approximately 50-100 AGL) the engine started to spudder/run rough. He looked down to see if the boost pump was on (and it was) and then increased the mixture. The aircraft started to lose power, speed and altitude. The pilot turned approximately 40 degrees to the right to head for lower terrain.
