估计上次振颤试飞之后发现新问题了。延迟交付也不一定是坏事，民用机对安全系数的要求比较苛刻，问题发现得越早越好
这又是为什么啊~~~~开学去打听打听
没有权威来源，不要轻信。
楼主的消息来源，不过是论坛上一个普通网民的话。

First delivery of the Commercial Aircraft Corporation of China (Comac) ARJ21 regional jet is likely to be delayed by up to a year or more, after problems surfaced during the flight testing programme.
Sources close to the programme, who spoke on condition of anonymity, said the airframer is not likely to deliver the first aircraft to launch operator Chengdu Airlines by end-2011 as scheduled.
A Comac spokesman was not able to comment on the reported delay. Chengdu Airlines was uncontactable for comment.
Among the problems faced by the airframer is the incorrect positioning of aircraft probes which resulted in inaccurate readings during flight testing, said sources.
The programme has also not completed its icing tests, said a source, adding that this makes it difficult for the ARJ21 to receive its type certificate by year-end.
"There isn't much time left, the icing tests were supposed to be completed in the first half of this year but they were not," he added.
Sources said the US Federal Aviation Administration (FAA), which is conducting a shadow certification of the programme and is assessing the Civil Aviation Administration of China's (CAAC) ability to assess the aircraft, has played a part in pushing for further testing of the ARJ21.
A FAA spokesman said the agency cannot discuss details of the shadow certification as it is still active. "We are observing the CAAC as they certify the aircraft. We will observe testing, review certification data, and observe meetings with the certification applicant; the CAAC defines the actual certification requirements," said the spokesman.
Comac has said it intends to apply for FAR 25 certification after the ARJ21 passes this shadow certification, so the aircraft can be marketed overseas.
是测试中检测出问题。

延期是肯定了，但说延一年？！
这东西本来就是练练生产流程经验的，问题层出不穷不值得大惊小怪
盼望着兔子的大飞机
看到这个消息，心里很是欣慰，说明arj21至少试飞过程还是在FAA有效监控下。
FAA监督之下，忽悠变得很艰难了。
上次不是说探头安装有误，引起测试数据偏差吗？如果是这个原因，是否意味着之前的飞行数据不准确，要重新飞？
不是把大哥
怕啥。。。F-35还要延期5年呢。。。

不一样，ARJ21的市场竞争者很多。

颤振没问题，问题不在颤振
大运呢？希望军方的项目能顺利一些，加油机、预警机全指望它呢。问题在起落架太短，大侧风降落时容易翼尖触底事故。
MD多次发生这事了

好事多磨啊
应该没有太大的问题，估计最多拖延两三个月时间交付。
试飞大纲要求达到3000小时，现在才飞了1800多，还差好多，必须飞完的。飞行包络进行修改了，COLLINS的通讯系统又有问题
还有1200个小时啊，那一年时间也合理了
就是MD80按比例改变
飞机截面完全一样，结构还超重，没什么希望的JJ。

会不会最后变成纯练手的项目了。。会不会和J7III那样悲剧的订单数量。。。然后将重头放在C919上{:soso_e103:}

怎么觉得像是练手的？
意料之中。。。
