China's civil aviation regulator has set up an airworthiness office at the home of the manufacturer of the country's first homegrown passenger jet in a move aimed at greater productivity. 

The decision by the Civil Aviation Administration of China (CAAC) to set up on-site at Commercial Aircraft Corporation of China (COMAC), developer of the C919 and ARJ21 airplanes, is the first time it has done so at an aviation manufacturer.

"It is an innovative way to enhance efficiency of the airworthiness certification of the C919 and other domestic commercial airplane models and accelerate their speed into the market," according to the CAAC.

COMAC is leading China’s efforts to become a key player in the global civil aerospace market. The move is expected to help the aircraft manufacturer establish system and capacity and develop its aircraft according to airworthiness requirements.

The office will also benefit the country's civil aviation authorities in shaping airworthiness management according to national conditions.

COMAC is the developer of the C919 large passenger airplane and ARJ21 regional jetliner.

The C919, China's first trunk jetliner, conducted a successful maiden flight on May 5, 2017, and is in the flight test phase.

The ARJ21 is China's first regional jetliner, with 78 to 90 seats and a range of 3,700 km. It began commercial flights on June 28, 2016, with mass production starting September 2017.
