Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that the takeoff run and liftoff appeared normal, but after liftoff the aircraft veered to the right (into the crosswind). The pilot attempted to correct with left rudder and aileron. When he was unsuccessful, he retarded throttle. The plane struck the ground with the right wing and right landing gear, started to ground-loop, hit two pedestrians and a parked a/c.
