 The Chinese aircraft equated to the An-24RV, having a full complement of windows and the booster jet engine.The majority of early deliveries were to the People's Liberation Army Air Force (PLAAF), mostly as transports, with a few in 52-seat airliner configuration for the Civil Aviation Administration of China (CAAC).After the initial licensed production run, the Y-7 was developed separately from the An-24 with a succession of upgrades culminating in the Xian MA60 (Modern Ark) series.
