A C919 airplane takes off from the Shanghai Pudong International Airport for a test flight to Xi'an, Northwest China's Shaanxi province, on Nov 10.
Watching the C919 soar into the sky during its maiden flight in May simply underlined China's ambitious commercial aviation program.
The country's first domestically-built large passenger jet is a single-aisle model similar to the Boeing 737 and the Airbus 320.
With its elegant design and narrow-body airframe, the C919 is testament to the prowess of manufacturer Commercial Aircraft Corp of China, or COMAC for short.
But away from the runway razzmatazz, the real work has just begun to obtain the airworthiness approval in China and then from overseas markets.
Already the C919 has attracted 785 orders from 27 Chinese and international customers. But to expand its overseas sales, it will need to comply with stringent global safety regulations.
A new agreement with the United States has helped pave the way to meeting those standards.
In October, the Civil Aviation Administration of China, known as CAAC, and the US Federal Aviation Administration, or FAA, announced they would validate the regulatory standards of both countries.
The Implementation Procedures for Airworthiness, or IPA, will adopt the regulatory systems of both nations under the US-China Bilateral Aviation Safety Agreement, which was created in 2005.
This should help shorten the C919's review procedure in obtaining an airworthiness certificate by the FAA, although the aircraft still faces various other safety checks.
COMAC has called the agreement "a significant step" forward.
The aviation manufacturer pointed out the European Aviation Safety Agency, or EASA, is in the process of certifying the airliner under the China-European Union air safety agreement.
Xu Chaoqun, an official at the CAAC, stressed the new accord is thoroughly comprehensive and shows the world's second largest economy is now a global player in the civil aviation world.
During the next 20 years, domestic airlines are expected to purchase 7,240 aircraft valued at $1.1 trillion, a Boeing China Current Market Outlook report released in September highlighted.
By 2036, single-aisle jets will continue to serve as the workhorses of domestic and regional fleets in China, the world's fastest-growing aviation market.
