From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Upon trying to touch down in what he said was a normal attitude the aircraft began to bounce up and down in a pretty violent manner. He initiated a go-around and proceeded to try another landing using an approach speed of approximately 60-65 knots and the aircraft again initiated some bounces but he was able to land ok. He notified his mechanic and on 10/23/2006 the pilot privacy data omitted showed up and discussed the problem with his mechanic. The mechanic stated that the technical term that caused it was "ground resonance oscillation." The mechanic stated that he had serviced the strut with air and grease and that it was good to go. The pilot privacy data omitted departed P33 on 10/23/2006 to do a couple of touch and gos. He stated that the wind was right down runway 03 and upon attempting a normal landing the aircraft proceeded to bounce up and down and the prop contacted the runway.
