A high-wing turboprop transport, designed as a commuter passenger/cargo civil aircraft, but used by some (about 15) air forces too. It was designed to replace aging piston engine Li-2, Il-12 and Il-14 fleet by more efficient turboprop design.
Aircraft may be easily converted from passenger to mail/cargo delivery configuration by removing seats and some cabin equipment. Navigation and communication equipment allows to operate An-24 in day- or night-time, under any weather conditions.
Aircraft proved to be very robust and reliable. It is capable to maintain 3000m altitude with maximum payload and one engine cut off. Unfortunately, exploitation by under-trained crews and ground service in developing countries, as well as violations of ground routine (funds shortages) recently resulted in numerous accident.
In service with Aeroflot since 1962, recently one of the oldest aircraft in passenger fleet carrying almost 40% of civil traffic. Aging planes suffered several crashes, and on March 28, 1997, all were grounded for detailed technical inspection. An-24 veteran fleet is expected to be finally grounded in 2000, when modern replacement aircraft will arrive, including the modern An-140 cousin.
For hot-and-high operations auxiliary RU-19A-300 unit was installed in the starboard engine nacell, modification was designated An-24RT. This engine also serves to supply electricity for ground services, providing independence from ground services.
