Probable cause

The student pilot failed to properly flare the airplane, made an improper recovery from the subsequent bounced landing. Contributing to this accident was the student pilot's total lack of experience and his improper use of the rudder.

Analysis

Before departing on the accident flight the student pilot received about a half-hour of dual instruction from a CFI. The CFI reported that the student pilot executed 9 touch & go takeoffs and landings in a competent manner and he allowed the student to perform his initial solo flight. On the first solo landing the student pilot improperly flared and the airplane bounced and began to porpoise. The student failed to properly recover from the bounced landing and when the porpoise stopped the airplane was angled toward the right side of the runway. The student improperly applied excessive left rudder and inadvertently entered into a ground loop, exited the left side of the 150-FT wide runway and collided with the soft terrain and nosed down.
