Comac is using a dual supplier system to manufacture critical and potentially challenging parts of the C919 airframe, to ensure quality control and to prevent any major delays to the programme.

These include the aircraft's aft fuselage as well as its vertical and horizontal stabilisers, all of which are made of composites, Comac's chief engineer Jiang Liping tells Flightglobal in an interview in

.

She explains that Chinese suppliers are unfamiliar with the use of composites and that the airframer's concern is that the quality and strength of the parts produced by one supplier may not match the required standards.

An example is how the first aft fuselage delivered by

Corporation had to be strengthened.

Comac also engaged two suppliers to build the C919's centre wingbox and mid fuselage due to anticipated complexities in the wing-to-body join of the aircraft.

"We do this so that we have a backup... the costs will go up but this is for quality control and also to ensure that the the programme's timeline is under control," says Jiang.

She adds, however, that Comac has stuck to the main suppliers thus far, since the manufactured parts have generally met standards.

Comac has largely completed the final assembly of the first flight test aircraft for the C919 programme, and is working towards a year-end roll-out followed by first flight in 2016.

Comac says C919 suppliers are due to deliver all systems of the first aircraft by October, allowing the aircraft to be rolled out by the end of 2015.

Speaking to Flightglobal at Comac’s final assembly centre near

Leap-1C engine, as well as the Liebherr landing gear. The aircraft's second powerplant is due to in September.

After roll-out, aircraft 101 needs to undergo a series of pre-flight preparations, including engine tests, lightning tests and taxi tests before it can make its first flight.

Under the best circumstances, pre-flight preparation could be completed within four months following roll-out, says Jiang. This means that the C919 could make its first flight around April or May of 2016.

When Flightglobal visited the manufacturer's sub-assembly hangar, aircraft 101 was resting on struts with its wing-to-body join completed. Comac had removed the aircraft's tail cone, as well as its vertical and horizontal stabilisers as it had to strengthen the composite aft-fuselage, says Jiang. The aircraft's windows have also been replaced with smaller standard-size ones, after the manufacturer discovered that its original larger windows affect the strength of the fuselage.

The aircraft's radome as well as the winglets have not been attached. Jiang says the airframe will move to the final assembly hangar next month, where its engines will be attached and systems installed.

Next month, Comac will also start final assembly of aircraft 102 as well as a static strength test aircraft. The mid-fuselage of aircraft 102 has already been delivered, with other sections of the fuselage due to arrive by the end of the month.

China has begun assembling its self-developed amphibious aircraft—one that might be the world's largest.

Work on the aircraft began last month and is being undertaken by Chinese manufacturer Aviation Industry General Aircraft Company, in the southern city of Zhuhai.

Workers are still busying with the fuselage of the amphibious aircraft-AG600. The manufacturer’s vice president, Hu Zhian, said it will take another four months to finish the whole assembly. This aircraft will play a key role in forest fire control and maritime search and rescue.

Workers are still busying with the fuselage of the amphibious aircraft-AG600. The manufacturer’s Vice President Hu Zhian said it will take another 4 months to finish the whole assembly. This aircraft will play a key role in forest fire control and maritime search and rescue.

"To extinguish forest fires, it can take on 12 metric tons of water from a lake or sea within 20 seconds to pour on the fire. The aircraft can carry 50 people on a maritime search and rescue mission. It will have an operational range of above 4,000 kilometers," Hu said.

Powered by four turboprop engines, it will be the world's largest amphibious aircraft, as far as its maximum takeoff weight and flight range are concerned.

"This amphibious plane is one of the three big plane projects approved by the State Council. It is a key facility of national rescue mission projects. It’s multi-functional. The making of this plane also fills a gap in China's general aviation industry," Hu said.

The aircraft maker has already received 17 domestic orders. Many global buyers have also shown their interests.

The entire aircraft is likely to be ready by the end of 2015 and will undertake its first maiden flight by the first half of 2016.

Because of its overall advantages, the company is confident that the aircraft will take a big share in the global market in the years to come.

COMAC ARJ21 to enter service in February 2016

Sep 2, 2015

The Commercial Aircraft Corporation of China (COMAC) said China's first regional commercial jet, the ARJ21-700, will enter service in February next year. Entry into service will follow two months of pilot training and bedding-in trials.

The long-delayed delivery of the first operational ARJ21s has seen launch customer to Chengdu Airlines defer delivery of its first two aircraft from the original date of 2006 to November this year—eight years later than scheduled.

The Civil Aviation Administration of China (CAAC) granted a

to the ARJ21 at the end of December 2014, but the program has seen subsequent developmental delays that included final cabin interior design refinements, some aspects of anti-icing operation, and cockpit event awareness and instrumentation updates.

The design has undergone several major revisions since inception—from the local production of the original General Electric CF34 power plants to newly designed wings and landing gear upgrades retrofitted to withstand extreme condition operations.

Although CAAC has not yet granted full production type approval, COMAC expects it will be granted toward the end of the year, enabling the manufacturer to begin supplying aircraft for its near 250-strong order book.

On top of the 30-aircraft order placed by COMAC subsidiary Chengdu Airlines, the majority

for the aircraft will go to Chinese or Asian carriers, including Xiamen Airlines, Lao Airlines, and at least two China-based leasing companies.

Chengdu Airlines currently operates an all-Airbus A320 fleet of 19 aircraft, but likely plans to use the 90-seat ARJ21s for short regional schedules to tier-two destinations such as such as from Chengdu to Shanghai and Qingdao.

I think that the entry of ARJ21 into service will finally show how good china aeronautic industry is at producing and maintaining planes and most importantly, how safe these planes are. The industry´s eyes will be at this plane, more than any of its competitors.
