THE domestically developed AC352 mid-sized utility helicopter has completed the flight test phase of the airworthiness certification process, the Aviation Industry Corp. of China (AVIC) announced Thursday.

The AC352 helicopter Thursday completed the last subject in the airworthiness certification process of the civil aviation authorities, said the AVIC, China’s leading aircraft maker.

It signified that the AC352 helicopter model has entered the final phase before gaining the airworthiness certification, the AVIC added.

The AC352 helicopter’s flight test included 87 subjects, such as takeoff and landing, level flight, climb performance, as well as stability and low-speed operation, among others, as required by the civil aviation authorities to verify the new helicopter model’s diverse performance, with a total test duration of 37.25 flight hours.

Civil aviation authorities have systematically evaluated its performance, control quality and the working conditions of its onboard facilities, the AVIC said.
