Probable cause
The pilot's failure to maintain directional control. Factors include a crosswind gust.
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 student pilot failed to maintain aircraft control when his Boeing B-75 encountered a crosswind gust just after touchdown. The pilot attempted a recovery using differential braking and rudder application, but the aircraft flipped-over near the left edge of the runway.
