Probable cause

The pilot's improper flare, which resulted in a bounced landing, and subsequent loss of control during an attempted go-around maneuver.

Findings · 2

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the airplane hit hard upon touchdown and bounced. The pilot tried to recover by applying full power and initiating a go-around but realized that the airplane was not climbing at a sufficient rate to clear power lines. As the pilot pulled back on the control stick to try to increase the rate of climb, the airplane stalled. The pilot pushed the controls forward to recover from the stall and maneuvered the airplane toward a swamp area to avoid impacting trees. The airplane landed hard in the swamp area beyond the extended runway centerline and sustained substantial damage to the fuselage and left wing. A postaccident examination of the airplane did not reveal evidence of mechanical malfunctions which could have contributed to the accident.

Factual narrative

The pilot reported that the airplane hit hard upon touchdown and bounced. The pilot tried to recover by applying full power and initiating a go-around but realized that the airplane was not climbing at a sufficient rate to clear a set of power lines. As the pilot pulled back on the control stick to try to increase the rate of climb, the airplane stalled. The pilot pushed the controls forward to recover from the stall and maneuvered the airplane toward a swamp area to avoid impacting a stand of trees. The airplane landed hard in the swamp area beyond the extended runway centerline, and sustained substantial damage to the fuselage and left wing. A postaccident examination by a Federal Aviation Administration inspector did not reveal evidence of mechanical malfunctions which could have contributed to the accident.
