What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot was departing runway 23 at approximately 1500 local time. He reported that at approximately 50 ft AGL the engine 'surged' then came back, then 'surged' again. The engine lost power and he attempted to 'pump the throttle' a couple of times. The aircraft touched down beyond the departure end of the runway and to the left side of the runway. The aircraft struck a ditch with the nosewheel, causing it to shear off. The left wingtip contacted the ground and substained substantial damage to the wing spar. The aircraft came to rest approximately 50 feet after the wingtip struck the ground. Investigation found the aux fuel pump in the 'on' position. The procedures in the POH call for the aux fuel pump to be off for takeoff. It was later determined that this had no bearing on the engine failure.
