The pilot stated that the accident occurred when directional control was lost during the landing rollout, resulting in a slow right turn during which the airplane exited the runway, and stopped about 20 feet from the runway edge, in the opposite direction. According to the pilot, there had been no previous mechanical failure or malfunction with the aircraft, or any of its systems, prior to the accident. ## Factual narrative On May 30, 2001, about 1642 central daylight time, a Cessna A188B, N4893R, registered to, and operated by Londe Air Service Inc., as a Title 14 CFR Part 91 personal flight, ground looped during landing at Humboldt, Tennessee.

According to the aircraft owner, the pilot was about a 4,000-hour agricultural pilot, who was being considered for employment with his company. The owner further stated that the pilot had taken the aircraft, stating that he would taxi it around and familiarize himself with its handling characteristics, and during the course of the familiarization he decided to fly the aircraft. The owner said that while the pilot was landing the aircraft, it ground looped 180 degrees, and the side load imparted to the tail section ripped the tailwheel off the empennage at the attach points, bending the bulkhead. The pilot stated that the final approach and flare were normal, and the accident occurred when directional control was lost during the landing rollout, resulting in a slow right turn during which the airplane exited the runway, and stopped about 20 feet from the runway edge, in the opposite direction. The pilot further stated that the tailwheel and fuselage were damaged as a result of the accident. According to the pilot, there had been no previous mechanical failure or malfunction with the aircraft, or any of its systems, prior to the accident. ## Aircraft - Registration: [N4893R](https://openairdocs.org/deregistered/N4893R-2006-10-11), registration cancelled 2006-10-11, S/N 18802411T, built 1975 (OpenAirDocs) - Reported make and model: Cessna A188B - Registry model: [Cessna A188B](https://openairdocs.org/model/cessna-a188b) (registry code 2073005) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18802411T - Airframe hours: 4139 - Engines: Teledyne Cont IO-520D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Londe Air Service Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, May 4, 2001, 2 hours before - Departed: M53, Humboldt, TN - Airport: M53, Humboldt Municipal, runway 04, 4,003 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
