MRJ attributes programme delay to US FAA's delegation process

http://www.flightglobal.com/news/articles/mrj-attributes-programme-delay-to-us-faas-delegation-process-390011/

"In a phone interview with journalists, the company's head of sales
Yugo Fukuhara says the Mitsubishi MRJ regional jet is the first
aircraft to fully apply the US FAA's organisational delegation
authorisation (ODA) system, which came into effect in 2009. The ODA
was partly applied to the Boeing 787 programme when Boeing was
delegated some responsibilities for performing tests to show that the
aircraft's lithium-ion battery complied with airworthiness
requirements.

Under the ODA system, Mitsubishi is delegated the authority to
design, test and analyse procedures and test results to show
airworthiness requirements. This means that it also has to invest
significant time and resources to develop the required processes.

"With this new system, all design and manufacturing internal processes
must be documented in advance and approved by the authorities. We need
to build new processes to validate compliance not only for ourselves,
but also for all our component partners," says Fukuhara. "Our partners
are aware of this new system, but we have to integrate their old
system into our new processes, and this needs a long time.""

日本を狙い撃ちにしたルールの変更ではないんだろうけど，これでは開発の
手間暇が増大しますな．
MU-300 の昔でも，DC-10 事故の影響で FAA の type certification が大幅に
厳しくされ，MU-300は基準改正後の試験対象第一号になって開発遅れた．

で触れられている型式証明の変更は割と最近だったのだな．
