Incident
Shortly after departing from Osaka-Itami Airport, the crew of flight JD621, bound for Okinoshima (Oki Island), reported technical problems to air traffic control and received clearance to return for an emergency landing. The aircraft touched down on runway 32R. During the landing roll, a tire on the right main landing gear burst, leading to a loss of control. The airplane veered to the right, left the runway, and contacted soft ground. It subsequently passed over a drainage ditch before coming to rest. All 22 occupants were evacuated safely. The aircraft sustained damage beyond repair.
Probable Cause
According to the official investigation, the probable cause of the incident was a hydraulic oil leak resulting from a loose connection of the hydraulic oil line in the left flap well.
