Beijing, The Indonesia Post – The AC352 medium-sized utility helicopter developed by China has completed the flight test phase of its airworthiness certification process, the Aviation Industry Corporation of China (AVIC) announced on Thursday (12/5).
The AC352 helicopter on Thursday completed the final subject in the civil aviation authority’s airworthiness certification process, said AVIC, China’s leading aircraft manufacturer.
This indicates that the AC352 helicopter model has entered the final stages before obtaining airworthiness certification, according to AVIC.
The flight test of the AC352 helicopter covered 87 subjects, including takeoff and landing, flat flying, climb performance, and stability and operation at low speeds, as required by civil aviation authorities to verify the performance of various new helicopter models, with a total of test duration 37.25 flight hours.
Civil aviation authorities have been systematically evaluating the performance, quality of control and operational conditions of the facilities on board the helicopter, AVIC said.
For the next step, the AC352 will carry out a number of other flight tests to further verify its various functions and reliability, AVIC said.
Developed by AVIC Harbin Aircraft Industry, the AC352 is a medium-sized twin-engine utility helicopter. The helicopter can carry up to 16 passengers with a maximum take-off weight of 7.5 tons.
The AC352 successfully made its maiden flight on December 20, 2016 in Harbin, Heilongjiang Province, northeast China.
The helicopter began its flight test journey to obtain airworthiness certification at the end of 2019. The model’s performance has been fully verified in previous flight tests in high temperature, low temperature, sub-high altitude and other complex environments across China, AVIC said.
The AC352 has added to the lineup of China’s civilian helicopter family in the 7-ton class, the developer said. (ojn/bbs)
