ASX Accident Report
On April 25, 2025, a Viking DHC-6-400 Twin Otter aircraft, registration 36964, operated by the Royal Thai Police Aviation Division, crashed into the Gulf of Thailand approximately 100 meters offshore from Cha-am Beach, Phetchaburi province. The aircraft, call sign RTP964, had departed from Hua Hin Airport at approximately 8:08 a.m. local time for a test flight following recent maintenance procedures. The aircraft was carrying six individuals: three pilots, two mechanics, and one aircraft engineer. Initial reports indicated all occupants perished at the scene, but later updates clarified that one pilot, Pol Capt Chaturong Wattanapaisarn, initially survived the impact and was transported to Hua Hin Hospital where he later succumbed to his injuries.
The Twin Otter had been undergoing a post-maintenance test flight in preparation for a scheduled parachute training operation. According to preliminary findings, the aircraft lost directional stability shortly after takeoff. Witness video captured the aircraft climbing briefly before entering a steep nose-down attitude and crashing into the sea, breaking apart upon impact. Local meteorological conditions at the time were stable, with light winds and good visibility reported by Hua Hin Airport METAR observations. Despite the pilots’ efforts to regain control, the aircraft descended rapidly and submerged in shallow coastal waters close to a populated resort area.
Authorities confirmed the deceased as members of the Royal Thai Police Wing, including senior pilots and technical maintenance personnel. The aircraft, manufactured by Viking Air in 2017, was part of a fleet delivered to Thailand in 2020. It was powered by two Pratt & Whitney PT6A-34 turboprop engines and was known for its versatility and short takeoff and landing capabilities. Prior to the crash, the aircraft had been based at Don Mueang Airport and was typically deployed for a variety of tactical operations including medical evacuation, cargo transport, and search and rescue missions.
Investigative attention quickly focused on mechanical failure as a possible causal factor. Officials disclosed that prior maintenance work had addressed issues involving a wing strut and the flight control stick. Early indications suggest that a catastrophic right engine failure occurred during the initial climb phase. However, the exact sequence of events remains under review pending further analysis of the wreckage, flight data, and mechanical logs.
