    When developing new aircraft, it is necessary to conduct, at the final stage, static strength testing and fatigue testing for the entire aircraft structure and verify and ensure its strength performance. In fatigue testing, aircraft loads corresponding to multiple flight patterns are repeatedly applied from several thousands to several tens of thousands of times, using more than one hundred different types of loading equipment. Interruptions of the test due to abnormalities caused not only in the test piece, but also the equipment being tested, results in longer lead times for development. This report presents a case of digital twin technology applied to a loading equipment as a system for the early detection of abnormality signs in equipment to minimize delays in testing. Using such systems, it becomes possible to conduct testing with enhanced reliability.
