The Xian MA700 (MA for 新舟, "Modern Ark") is a twin-engine, medium-range turboprop airliner currently under development by Xi'an Aircraft Industrial Corporation of the Aviation Industry Corporation of China (AVIC). DevelopmentWhen the aircraft was first announced in 2007, it was presented as a 70-seat aircraft. However, when a model of the aircraft was shown at the 2008 Zhuhai Airshow, it was touted as capable of offering about 80 seats in 4-abreast configuration.[1] Preliminary design was reviewed in January 2017, before detailed design.[4] Okay Airways and Joy Air were announced as launch customers for the aircraft and to be involved with its development, which had been due to make its maiden flight in November 2019.[2][3]By late 2017 there were 185 orders for the 86-seat aircraft with purchase agreements with 11 customers including Joy Air, Okay Airways and Cambodia Bayon Airlines. The first prototype had been due to be assembled in 2017, with a maiden flight in 2019 and certification scheduled for 2021. AVIC plans to apply for airworthiness certification with the United States' Federal Aviation Administration and the European Aviation Safety Agency so the plane can enter the Western market.[3] Long-lead items like flap and cargo door structures started to be built from December 2017.[4] In December 2017, Dowty Propellers was selected for a R408 propeller derivative. Manufacturing of its flaps and cargo door had begun in Xian and Shenyang, respectively. In January 2018, AVIC said structural and strength tests allowed to release wing flaps and forward fuselage technical specifications. Maiden flight is targeted for November 2019, and Chinese certification by 2021 before introduction.[4]The first should be rolled out around the middle of 2019 and first delivered in 2022.[5] While detailed design was to be completed by April 2018, the program slipped three years since its launch at the end of 2013, and Avic has not yet built a reputation for dependable products.[14] Design of major assemblies like the fuselage sections and wingboxes was sent to factories in late May 2018, to be constructed by the end of the year. Structural design was finalized by June 2018 while 25-26 systems critical design reviews were completed. Others should be completed by August and systems should be delivered from October for integrated system testing. Technical manuals will be written in the second half of 2018.[4]The first MA700 should be rolled out in June 2019 before a few months of ground tests including taxi runs. The PW150C should get certification by 2019 end. Avic expects the EASA and FAA to validate the CAAC certification, anticipated for 2021 after 24 months of flight testing. Avic sibling Comac needed six years for the ARJ21 and the C919 may need at least four years.[6] In July, Avic selected Rockwell Collins, Thales, Meggitt and Parker Hannifin as suppliers at the Farnborough Airshow.
