Franklin-Macon County, United States of AmericaLanding (descent or approach)

On March 15, 2012, a Cessna 501 Citation I (registration N7700T) operated by BigTex Trailers was involved in an aviation accident near Franklin-Macon County, United States of America during landing or approach. 5 people were killed. Investigators recorded the probable cause as: The pilot's failure to achieve a stabilized approach, resulting in a nose-first, bounced landing. Contributing to the accident was the pilot's activation of only one thrust reverser, resulting in asymmetrical thrust. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A pilot unfamiliar with the mountain airport executed two high approaches. During the second, the nosegear touched down halfway, bounced, and the aircraft banked right. The right wing struck the ground, the aircraft flipped, and a postcrash fire occurred. No preimpact mechanical issues were found.

Incident Overview

A pilot conducted a visual approach to a mountain airport with which he was not familiar. The aircraft was high on the first approach, prompting a go-around. The second approach also began high, but the approach angle steepened, causing the aircraft to pitch nose-down toward the runway. The nosegear touched down approximately halfway down the runway, followed by main gear touchdown. The aircraft then bounced, and the sound of engine noise increased as it banked right. The right wing contacted the ground, and the aircraft subsequently flipped over and departed the right side of the runway. A postcrash fire ensued.

Examination Findings

Postaccident examination of the airframe and engines revealed no preimpact mechanical malfunctions. The examination showed that the right engine thrust reverser was deployed during the impact sequence, while the left engine thrust reverser remained stowed. Manufacturer data indicates that single-engine reversing has been demonstrated during normal landings and is easily controllable. However, at the time of the activation, the aircraft had already porpoised and bounced during the landing. The pilot's activation of only the right engine's thrust reverser would have created asymmetrical thrust and most likely exacerbated an already uncontrolled touchdown.

Additional Context

The source notes that had the touchdown been controlled, the aircraft could have stopped on the remaining runway or the pilot could have performed a go-around uneventfully.

Probable cause

The pilot's failure to achieve a stabilized approach, resulting in a nose-first, bounced landing. Contributing to the accident was the pilot's activation of only one thrust reverser, resulting in asymmetrical thrust.
