Synopsis
On 24 September 2015, a Diamond DA40 aircraft, registration HS-IAF, operated by the International Aviation College of Nakhon Phanom University, departed from Nakhon Phanom Airport with an instructor pilot and three passengers. The aircraft stopped at U-Tapao Rayong Pattaya International Airport for refueling before proceeding to the temporary takeoff and landing area for aircraft at Nong Kho reservoir in Sriracha district, Chonburi province. After arriving, the instructor pilot performed low passes to observe the glide paths of runways 24 and 06. The aircraft touched down on runway 06 but was unable to stop on the runway, ran into a tyre barrier, overran to the left, and collided with an embankment. The accident occurred at approximately 14:25 hours local time. The aircraft sustained substantial damage; the pilot and all three passengers exited safely.
