Analysis
On June 24, 2022, about 1425 central daylight time, a Bücker BU-133, N1940H, was substantially damaged when it was involved in an accident near Hartford, Kentucky. The private pilot was seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
Witnesses reported that the pilot refueled the airplane and started the engine with the assistance of a mechanic, who hand-propped the engine. After engine start, the pilot taxied for departure. The airplane became airborne about 1,000 ft down the 5,000-ft-long runway and immediately pitched up into a nose-high attitude with little increase in altitude. The witnesses also reported that the engine ran smoothly during the entire event. As the airplane passed the departure end of the runway, it made a slight right turn, followed by a sharp turn to the left, back toward the runway. The airplane stalled, the nose dropped, and the airplane impacted the ground. First responders assisted the pilot out of the wreckage and he was transported to a local hospital for treatment.
An inspector with the Federal Aviation Administration (FAA) responded to the accident site and examined the wreckage. The airplane crashed in an open, grassy area about 400 ft past the departure end of the runway. The left wing and forward fuselage sustained substantial damage. There was no fire. Continuity was established from all flight control surfaces to the cockpit controls. The elevator trim was found in the neutral position.
The FAA reported that, due to his injuries, the pilot had no recollection of the event.
