Probable cause

Pilot's failure to maintain directional control during the landing roll, and his excessive brake application as the aircraft departed the runway, which resulted in the aircraft nosing over. The pilot's inexperience in taildragger aircraft, and the inadequate supervision on the part of the check pilot were contributing factors.

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

While on an aircraft familiarization flight, during the landing roll, the pilot-in-command allowed the aircraft to drift to the left and depart the left side of the runway. As the aircraft departed the runway, the pilot applied both brakes 'hard', and the aircraft nosed over in the grass. The check pilot in the front seat had no access to brake pedals.
