Probable cause

The pilot flaring too high, and his inadvertent pilot-induced oscillation during the landing flare/touchdown. Contributing to the accident was the collapse of the nose landing gear.

Findings · 3

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 landing approach was uneventful up to the flare and touchdown. He increased engine power just prior to landing because he thought the airplane was slow. He flared higher than normal, and then the airplane "hit hard" on all three landing gear. The airplane began to porpoise, contacting the runway alternately with the nose and main landing gear, but eventually settled onto all three landing gear. The airplane then made an uncommanded left swerve that the pilot was unable to counteract. The nose landing gear separated from the airplane when the airplane nose impacted a non-breakaway steel runway light. The airplane then nosed over in the grass easement off the left side of the runway. The cabin roof, engine firewall, rudder, and vertical stabilizer were substantially damaged.

Factual narrative

The pilot reported that the landing approach was uneventful up to the flare and touchdown. He increased engine power just prior to landing because he thought the airplane was slow. He rounded-out and flared higher than normal, and then the airplane "hit hard" on all three landing gear. The airplane began to porpoise between the nose and main landing gear, but eventually settled onto all three landing gear. The airplane then made an uncommanded left swerve that the pilot was unable to counteract. The nose landing gear separated from the airplane when the airplane nose impacted a non-breakaway steel runway light. The airplane then nosed over in the grass easement off the left side of the runway. The cabin roof, engine firewall, rudder, and vertical stabilizer were substantially damaged. The pilot was seriously injured with a broken neck. The airplane was not equipped with shoulder harnesses.
