Detection and Initial Assessment
The crack was discovered on 19 June during a routine post-flight inspection following an aerial target training mission. Technicians identified the defect in the lower bulkhead of the main landing gear tension strut lug on the aircraft’s right-hand side. The issue was detected using non-destructive inspection methods in line with international standards. Lockheed Martin representatives later confirmed the defect and issued a field service report advising against a one-time ferry flight for repairs, highlighting the need for maximum safety precautions.
Transport and Repair Measures
The Air Force outlined four steps to address the issue. First, consultation and planning between relevant units determined how to safely move the aircraft from Wing 106 at U-Tapao to the main maintenance base in Nakhon Sawan. Second, the F-16 was partially dismantled and loaded onto a C-130H transport aircraft for relocation. Third, repairs are being carried out jointly by RTAF personnel and Thai Aviation Industries Co., Ltd. (TAI), the Air Force’s strategic maintenance partner, following strict quality and safety standards.
Safety and Operational Readiness
Air Marshal Prapas Sornsaidee emphasised that flight safety was never compromised, as the affected aircraft was grounded immediately upon detection. Other F-16s underwent safety checks and passed inspection, ensuring operational readiness remains intact. The incident also underscores the transparency and rigor of RTAF maintenance procedures and the engineering capabilities of personnel working alongside TAI. “The Royal Thai Air Force is committed to ensuring the highest levels of safety for our pilots and personnel while maintaining public confidence in our operational readiness,” he stated.
