## Analysis

The pilot initially reported that the airplane landed "a little hard" and he performed a go-around. During the second landing, the right main landing gear collapsed and the airplane departed the right side of the runway. In a subsequent statement, he described the first landing as a "bounce" and suggested a phenolic block in the airframe landing-gear support structure had failed, which resulted in the gear collapse and substantial damage to the airplane. Examination of the wreckage and photographs by a Federal Aviation Administration (FAA) aviation safety inspector revealed that an aluminum landing gear bracket as well as the surrounding structure failed due to impact and overload.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
