Accident Number: CEN22LA128

Flight Conducted Under: Part 91: General aviation - Instructional
On February 20, 2022, about 1115 central daylight time, a Ryan L-17B airplane, N5042K, was substantially damaged when it was involved in an accident near Livingston, Illinois. The private pilot, the flight instructor, and the passenger sustained no injury. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 training flight.
The pilot reported the purpose of the flight was to practice various flight maneuvers. The airplane departed at 0943, the training was successfully performed, and was enroute back to the departure airport. About halfway back to the airport, the pilot noticed the engine was “running rough.” The pilot proceeded to lean the mixture to correct the problem, and he then noticed that the manifold pressure/fuel flow gauge was “pegged.” The pilot continued to lean the mixture, he adjusted the throttle, and no response was received from his inputs. The airplane began to lose altitude and the pilot performed a forced landing to a flat muddy field. During the rollout, the nose wheel turned left in the mud, the airplane spun around, both wings and the propeller impacted the ground, and the airplane came to rest upright. The three occupants were able to egress from the airplane without further incident.
The flight instructor, who is also a mechanic, reported that when the engine was “running rough,” he tried to lean the mixture with no response. He also observed that the manifold pressure/fuel flow gauge indicated that the fuel flow needle had advanced passed the red line into the manifold pressure side of the gauge. He additionally reported that the throttle had no response and he assumed that the fuel control unit had a mechanical issue.
The airplane sustained substantial damage to both wings. The airplane is pending recovery from the field for a future examination of the airframe and the Continental Motors IO-520Bengine.
