Probable cause

Failure of the pilot to maintain directional control of the airplane, which resulted in an inadvertent ground swerve. The pilot's lack of experience in the airplane was a related factor.

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 lost directional control of the airplane during takeoff roll. He reported that when control was lost, he probably overcorrected with left rudder due to his lack of experience in the airplane (2.5 hours). The airplane ground looped off the left side of the runway and flipped inverted in the grass. The pilot reported that local winds were calm.
