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 private pilot was attempting to land his single-engine airplane in a crosswind when the airplane drifted to the right of the runway and touched down. The left wing lifted and the pilot reacted by adding power for a go-around, but he then determined that a go-around was not a suitable option and reduced engine power. The airplane veered toward a fence and a road, so the pilot again added power in an attempt to lift the airplane over them. Subsequently, the left wing hit a telephone pole and a car. The pilot reduced power and the airplane skidded to a stop and remained upright on the landing gear. The pilot reported no mechanical deficiencies with the airplane and stated that he failed to maintain control of the airplane after touchdown while attempting to land in a crosswind.
