Comac CBJ-909
The COMAC ARJ21, sold domestically in China as the C909, was China's first indigenously developed regional jet, designed with substantial help from established Western suppliers for its engines and systems. It seats up to around 90 passengers and was built to reduce China's reliance on imported regional aircraft for its rapidly growing domestic route network. Development took far longer than planned, with the type entering service only in 2016 after a decade of certification delays. It has since become the direct technological stepping stone toward COMAC's larger C919 narrow-body, sharing lessons learned from its long certification process.

In CatchFlights the Comac CBJ-909 starts as a Legendary catch. The tier is an editorial judgement of how special a sighting of this type is. The more often you catch it, the closer it moves to Common for you. The first catch of a legendary type pays a bonus of its own.
A catch counts for the manufacturer Comac, the CBJ-909 family and the model in your collection, and the daily Type Rating quiz asks about the types of each family.
