On December 27, 2024, about 1309 mountain standard time, a Cessna 560, N753MB, was substantially damaged when it was involved in an accident at Stevens Field Airport (PSO), Pagosa Springs, Colorado. The pilot, copilot, 8 passengers and 3 dogs were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that she was conducting a takeoff on runway 01 with the intended destination of Tulsa Riverside Airport (RVS), Tulsa, Oklahoma. During the takeoff roll the airplane accelerated normally to the decision speed (V1) of 96 knots and rotation speed (Vr) of 103 knots, but was unable to rotate with full aft deflection of the control yoke. The pilot later stated that the airplane did not feel like it had enough power and did not seem to accelerate at the correct rate based on the calculated performance data. At an airspeed of 120 knots, the pilot performed a rejected takeoff with maximum braking and full reverse thrust. The airplane departed the end of runway 01 and continued into the grass beyond the runway. The airplane pivoted to the left and came to a stop in the grass. The crew and passengers exited the airplane and were met by airport personnel. A post-accident examination by a certificated airframe and powerplant mechanic revealed substantial damage to both wings. The airplane was retained for further examination.
