What happened
During a scheduled training mission at Yanzhou-Taizhou Airport, an aircraft departed from runway 35 at 13:59 local time. The flight was operated with a crew of three, consisting of one instructor and two pilots undergoing supervision. Following six successful landings, the crew repositioned themselves within the cockpit, placing the instructor in the left-hand seat and the trainee in the right-hand seat.
As the aircraft approached runway 35 for a subsequent landing, it maintained a height of approximately 50 feet before entering a steep descent. The aircraft crossed the runway threshold 500 meters beyond the threshold, positioned to the right of the centerline with a 4.5-degree deviation. During the landing roll, the aircraft experienced erratic lateral movement, veering left, exiting the runway, and then swinging back toward the runway surface. The aircraft eventually veered off the runway to the right, causing the loss of both main landing gears. The aircraft came to a final stop in a nearby grassy area.
Findings
While all three crew members managed to evacuate the aircraft without injury, the aircraft sustained damage that rendered it a total loss. The sequence of events indicates that the unstable descent and subsequent lateral oscillations led to the aircraft departing the paved surface and the structural failure of the landing gear.
