Lead

 * The lead is rather short. It should summarize the entire article.
 * 'By May 2018, 127 were in service' -> 'As of May 2018, 127 planes were in service'
 * Also are there more updated figures for this?

Development

 * The full name of the RRJ should be mentioned before using the abbreviated version.
 * 'Sukhoi targeted a market for 800 aircraft including 250-300 from Russia.' the sentence is vague. Does this refer to the number of aircraft they planned to sell? Please clarify
 * WikiLink to Boeing?
 * 'planning a 2006 first flight and 2007 service entry. ' This does not fit nicely with the previous part of the sentence.
 * 'Contenders for the engine......between 2003 and 2015.' Please rework the quoted section as i have no clue what anything is referring to
 * I dont think it is necessary to mention which engines were not chosen but only the one that was chosen.
 * Why are there so many wikilinks to the SM146?
 * Also please stick to either SM146 or SaM146
 * '10% of the regional jet market or/which amouted to 600 aircraft'
 * 'Messier-Bugatti-Dowty for the landing gear'
 * ' and B/E Aerospace for interiors.'
 * 'it was expected six months after the Russian approval.' Expected to what?
 * A source is needed for the sentence on the production plant.
 * 'The RRJ60/75 were then discontinued '
 * 'Boeing expanded its assistance on flight and maintenance crew training and manuals, and spare parts management and supply.' What was expanded? Please clarify. Also there are too many 'and's in the sentence.
 * 'The development was anticipated at $1 billion' is the 'development' refering to the SCAC?
 * ' the SaM146 engine was first run' > the first run of the SaM146 engine
 * 'On 29 December 2009, deliveries were delayed......including NPO Saturn quality problems.' Please make it clear from the start why the engines were not ready and it may not be necessary to mention the 4th plane flying with the 1st plane's engines as it sounds like trivia now.
 * 'noise was tested for certification authorities' these comical mistakes should not be in a GAN. The statement implies that there may be certification authorities in noise (which does not make sense lol)
 * 'emergency evacuation (completed in 73 seconds, within the 90 imparted, with 98 volunteers and five crew) and rejected takeoff, probing the tires and brakes at maximum energy with no thrust reversal, were completed in Zhukovsky near Moscow' the and should be the last of the three items
 * 'London City Airport is a major destination for Irish airline CityJet, which was to receive 15 SSJ100s' the connection to the SSJ should be made earlier in the sentence
