AT-6TH crashed not even one year into services

2026-01-29 - 05:31

An AT-6TH light attack aircraft assigned to Wing 41 in Chiang Mai crashed at about 10:30 on Tuesday. The Royal Thai Air Force has not yet said what caused the incident, and an investigation is under way. With few details available, the crash has raised questions about the AT-6TH itself — a model that only recently entered service with the air force and remains in the early stages of operational use in Thailand. The aircraft was inducted into service with Squadron 411 at Wing 41 in September 2025, meaning it had been in active service for less than a year. It was introduced as part of the air force’s plan to replace its ageing L-39 ZA/ART jet trainers, which had been in use for decades. Thailand has acquired a total of 12 AT-6TH aircraft, purchasing eight under a contract signed in 2021 and a further four in 2022. The fleet is relatively small, a factor that can place additional focus on training, maintenance and operational procedures when incidents occur. The AT-6TH is a turboprop light attack aircraft designed for a range of roles, including close air support, reconnaissance and surveillance. It can also be used for combat search and rescue missions. Such aircraft are typically valued for their flexibility and lower operating costs compared with jet-powered platforms. Although often described as a modern platform, the AT-6TH combines contemporary digital systems with an airframe concept that has been widely used for decades. Investigators will generally consider multiple possible factors in a crash, including mechanical issues, pilot workload, environmental conditions and maintenance practices. No conclusions have yet been announced in this case. The aircraft’s cockpit and flight systems are intended to support pilots transitioning from fighter aircraft, including a flight control system similar to that of the F-16 and a fully digital display layout. It is also equipped with systems that allow it to share data with other Royal Thai Air Force aircraft through the domestically developed Link-TH network. To support its introduction, Thailand’s first group of eight AT-6TH pilots completed training in the United States, covering flight operations, weapons employment and maintenance. All were certified as instructor pilots and test pilots before the aircraft entered service. The Royal Thai Air Force has said it will release further information once the investigation into the Chiang Mai crash is completed.
