This fatigue testing is an important part of the airworthiness verification activities for the HK-UK3-175 propeller. It focuses on evaluating the propeller's fatigue performance under specified loading conditions. The testing will be conducted in stages in accordance with the applicable requirements, with ongoing testing and data recording to assess the structural fatigue performance of the product.

Unlike routine performance testing, airworthiness-releated fatigue testing typically involves an extended test period, with specific requirements for test continuity, data recording, and result analysis. Therefore, the process must be carried out progressively in accordance with the established test plan.

With the commencement of fatigue testing, the HK-UK3-175 airworthiness verification process has entered an ongoing testing phase. We will continue to monitor the testing progress, analyze and evaluate the collected data, and proceed with the subsequent verification activities as planned.
