Commercial Aircraft Corp. of China (Comac) now aims to deliver its first ARJ21 regional jet toward the end of next year, representing another one-year delay in the program.
It had been aiming to have first deliveries by the end of this year, but Comac director general airworthiness management department, Zhao Yuerang, says they aim to finish the flight test program in April and the supplemental ground tests in June.
At the end of next year, we will complete (Civil Aviation Administration of China) type certification and have first delivery, he says. Zhao was speaking at the China International Aviation and Aerospace Forum on Nov. 15 in Zhuhai.
The ARJ21 has experienced several delays over the years. Previous delays were caused by weight issues and difficulties with systems integration.
But the latest delay is due to structural issues. Industry sources say the ARJ21s wing broke, during static testing before achieving ultimate predicted load. The wings failure then led the Civil Aviation Administration of China (CAAC) to limit the aircrafts flight envelope during its flight test program.
The sources say the structural issue has since been resolved because Comac has redesigned the aircrafts wing to make it stronger. The CAAC has responded by restoring the flight envelope to its fullest, add the sources.
Chengdu Airlines, in which Comac is a major shareholder, is to be the launch operator. Chengdu placed an order for 30 ARJ21s after Comac bought into the airline. The launch operator was originally supposed to be Shandong Airlines, but it decided to delay taking delivery of the Chinese-built regional aircraft. Shenzhen Airlines Kunpeng Airlines was next in line to be the launch operator, but it handed that mantle to Chengdu.
The ARJ21-700 is a 90-seat regional jet powered by two, fuselage-mounted General Electric CF34-10A engines.
China is hoping that once the ARJ21 receives Chinese certification, it will get FAA certification, making it the first Chinese commercial transport aircraft to receive U.S. approval. The FAA has agreed in-principle to embark on a shadow certification, which involves ensuring the CAAC certification process is in line with FAA standards.
Passing the shadow certification process would make it easier for the ARJ21 to get FAA certification. Having FAA certification would help Comac to sell the aircraft overseas.
Comac has sold the ARJ21 mostly to Chinese airlines. Its foreign customers are GE Commercial Aviation Services and the Laos Government. Laos is a political ally of China. GE is providing the engines for the ARJ21.
