What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
While conducting a maintenance test flight the pilot in command stated: "as we approached the west end of the field at about tree top level, we encountered a downdraft that pushed us lower than I was anticipating, landed short of the airfield and hit the lip of the irrigation ditch and flipped the aircraft."
Both the pilot and passenger sustained some scratches and bruises but were otherwise uninjured. The aircraft was inverted, facing west, there was a furrow in the ground extending from the edge of the ditch to aircraft created from the propeller and nose gear dragging the ground.
Investigation revealed that there are no maintenance issues with the aircraft at this time. In my opinion the probable cause of the accident was pilot error due to the pilot not being proficient in the aircraft. The review of the pilot in command's pilot flight logbook shows that his last biannual flight review per 14 CFR 61.56(c)(1&2) was July 20, 1993. The pilot in command logged 1 hour of flight time on July 15, 2023, and 0.7 hours of flight time on July 23, 2023. There has been a 30-year gap since the last biannual flight review for the pilot in command.
