The China-developed AC352 mid-sized utility helicopter has completed functionality and reliability tests in northeast China's Heilongjiang Province. An AC352 helicopter landed at the Harbin Pingfang Airport at 10:22 a.m. on May 28 after a flight of 616 kilometers, completing a ferry flight test on a long distance route. The completion of both tests signifies that the AC352 helicopter has entered the final phase of assessment and approval before obtaining the airworthiness certification required by civil aviation authorities.
