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 airline transport certificated pilot was departing on a Title 14, CFR Part 91, local area flight. It was the first flight after an extensive rebuild, and annual inspection of the airplane. The pilot said he conducted a preflight inspection of the airplane using its checklist, and had several maintenance items corrected before takeoff. He said that as the airplane became airborne, it immediately rolled to the left, and the left wing struck the runway. He pulled the engine power to idle, but was unable to correct the roll. The airplane pivoted to the left and nosed over. A postaccident inspection of the airplane by the pilot, maintenance personnel, and an FAA inspector, revealed that the aileron control cables were misrouted, and the aileron's direction of travel was reversed.
