Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The airplane settled onto the runway after becoming airborne during takeoff. The airplane became airborne a second time and this time it settled into a bean field off the end of the runway. The airplane then contacted a ditch and crossed a road prior to coming to rest in another bean field. The pilot stated the airplane was at or near gross weight, but he did not calculate the weight and balance. He stated the engine was running normal and he was confident the airplane was going to stay airborne which is why he did not dump the chemical load.
