NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot with one passenger on-board the airplane was practicing landings to familiarize the passenger with the airplane. During one of the landings, the airplane landed "firm." After noticing added noise in the cabin and the "seats being jarred” they taxied back to the hangar. The pilot reported that a fuselage tube had failed due to a "pre-existing weakened condition." The Federal Aviation Administration (FAA) Inspector who examined the airplane reported that the fuselage tube displayed evidence of corrosion.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The failure of the fuselage's tube structure due to corrosion during a hard landing.
