"The Superjet 100, made by Russia's Sukhoi and Italy's Finmeccanica, has been plagued by safety concerns since a plane crash in Indonesia last year. Finmeccanica told Reuters on Monday it wanted to restructure the Superjet joint venture or scrap it entirely."
"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.""
"Mitsubishi is now assembling its first flight test and ground test aircraft. Though Fukuhara could not put a figure on the percentage of system components that have been produced, he says that 90% of the jet's structure has been manufactured. He also adds that no parts had to be reproduced because of the ODA system.
Final assembly of the first MRJ test aircraft will start this autumn at Mitsubishi Heavy Industries' Komaki plant in Nagoya. Under the revised schedule, the first Pratt & Whitney PW1200G engines should be delivered to Mitsubishi in the spring of 2014."
"Mitsubishi Heavy gained the most in a month, rising 2.8 percent to 554 yen in Tokyo trading. The stock has added 33 percent this year, compared with a 31 percent advance in the Nikkei 225 Stock Average. "
“Investors reacted positively to this news as it’s a good move,” said Mitsuo Shimizu, a Tokyo-based analyst at Iwai Cosmo Holdings Inc. (8707) “There are high expectations for the jet.”
"Delegation of aspects of certification work has a long history in aircraft certification, but the ODA system is more extensive than the traditional approach, demanding that a whole organization, not just certain individuals in it, show its competence and its procedural compliance. At the level of a type-certificate holder, such as Mitsubishi Aircraft, the organization must also ensure that its suppliers comply. "
2. ODA について，ボーイングからのこのプログラムへのアドバイザー1名と， 三菱航空は海外の専門家多数(ボーイングの元社員含む)を雇っているとのこと．
"Although Mitsubishi Aircraft appears not to have sought special assistance for its ODA work, Boeing has been an adviser to the program and the Japanese company has hired many foreign experts, especially former Boeing employees, to help it with such development challenges as relations with suppliers, ground tests, flight tests and certification. "
"The source, from Taiwan's Aerospace Industrial Development Corporation (AIDC), which is designing and making slats, flaps, belly fairings, rudder and horizontal stabiliser rotating blades for the MRJ, says it has so far only delivered the metallic slats to Mitsubishi Aircraft.
The other parts, all made of composites, are undergoing certification and will only be progressively delivered to Mitsubishi from next March, he says."

"Certification of the Pratt & Whitney PW1200G geared turbofan is expected in the "latter half" of 2014, or at least six to 12 months after the scheduled first flight of the Mitsubishi Aircraft MRJ regional jet in late 2013.
Bob Saia, P&W's vice-president of the next generation product family, disclosed this while discussing the company's crowded development schedule."
