Probable cause

Instructor pilot's inability to recover control of the aircraft after it entered a spin.

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

A ground witness observed the aircraft at a low altitude, climbing, with the landing gear extended. He stated that he heard the engine sounds decrease and observed the aircraft roll over into a spin. The witness said the aircraft rolled inverted during one spinning turn but returned to an upright attitude before colliding with the terrain. Exam of the propellers indicated that the left propeller was feathered. Exam of the engines did not disclose any malfunctions.
