中国商飞ARJ21飞机适航认证再次推迟zz

Comac's ARJ21 regional jet is unlikely to receive certification until at least late next year, according to sources.

据消息人士透露，中国商飞的ARJ21支线飞机明年年底前不可能取得适航证。

This means the programme, which started about 11 years ago and originally had first delivery scheduled for 2007, will again be delayed.

这意味着这一11年前启动、最初计划于2007年首架交付的项目还将延期。

At Airshow China in Zhuhai in 2012, chief designer Chen Yong said the aim was for the ARJ21 to receive certification from the Civil Aviation Administration of China (CAAC) in the first half of 2013, and to deliver the jet to launch customer Chengdu Airlines in 2014. Thereafter, it could take up to two years before the aircraft was validated by the US Federal Aviation Administration, he added.

在2012年中国珠海航展上，ARJ21的副总设计师陈勇声称ARJ21取得CAAC适航证的目标定在2013年上半年，2014年交付给启动用户成都航空公司；此后可能要花2年时间来获得FAA认可，陈勇补充说。

Progress, however, has been slow, because the inexperienced airframer continues to work with the CAAC, which is certificating a commercial jet for the first time, and is unfamiliar with the process, sources say.

然而，进展一直迟缓，因为一起工作的一方是缺乏经验的飞机制造商，另一方是首次对商用喷气飞机进行适航审查且对过程不熟悉的CAAC，消息人士说。

It is understood that the ARJ21 has completed about 70% of the validation tests scheduled, and about 60% of flight tests necessary - so, it is almost impossible for the jet to be certificated this year. Publicly, the airframer said the ARJ21 passed several major milestones this year, including stall tests and minimum unstick speed tests - two high risk and critical tests of the programme.

据了解，ARJ21已经完成约70%验证试验，约60%必做的飞行试验，所以绝无可能今年取得适航证。根据公开的信息，该飞机制造商声称ARJ21年内已经取得一些关键进展，包括失速和最小离地速度试验，这两项均属于高风险的关键试验。

The slow progress of the ageing ARJ21 has largely been attributed to the five-year-old airframer's lack of experience and small talent pool.

老化的ARJ21步履蹒跚，在很大程度上应归咎于5岁的飞机制造商既缺乏经验又缺乏人才。

Comac has so far garnered 252 commitments for the ARJ21, mostly from Chinese airlines and leasing companies.

中国商飞至今已获得252架ARJ21承诺订单，绝大部分来自中国的航空公司和租赁公司。
