Probable cause

The pilot failed to maintain directional control by improperly using the rudders/tall wheel steering.

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 was practicing touch and go takeoffs and landings on runway 07. The winds were from the north at less that 5 knots. During the landing roll after the first landing, the airplane's tailwheel became erratic and the rudder control diminished as the airplane slowed down. The pilot delayed in applying full power, and when he did, the airplane ground looped.
