Probable cause

An inadvertent stall due to the failure of the pilot to maintain a correct airspeed during the approach.

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

In a statement to FAA inspectors the pilot said he was turning from base to final approach when the aircraft suddenly stalled. The aircraft mushed into the ground short of the runway. In his completed pilot aircraft accident report NTSB form 6120.1/2, the pilot said that he was thinking more about fishing than flying the aircraft during the approach to the airport. He noted that he should have 'paid more attention to his airspeed'. The pilot stated that there were no mechanical malfunctions or failures of the aircraft.
