ANTONOV-24 is a Russian medium size passenger aircraft, which was manufactured in the former Soviet Union. It was invented by a group of Russian engineers in 1950s under the management and leadership of Mr. ANTONOV, the inventor. Each AN-24 propeller engine, VICHENKO A.I.24, has 2,55 HP to lift the load and its body weights. In fact, its technical concept and architectural structure is quite similar to FOKKER-27, which produced in Pays-Bas, Holland. For the modernization purpose and the improvement of passenger air transportation services, AN-24 was the substitution for LISONOV-2 and ILYOUSHIN-14, which had used piston engines. It was launched for the test flight using the new turbo Propulseour engines crossing the southern area of the Soviet Union to Anta Tic Sea and the result was a technical and operable success. In the winter of 1962, AEROFLOT, the Soviet national airlines decided to use Antonov-24 with its capacity of 30 passengers only. Later the Russian specialists modified its techniques to make it possible to carry 50 passengers and five crews: two pilots, one mechanic one-radio operator and one air route guider.

After a short while in operation, research was carried out to enhance its engines system; apparently, one additional engine (RY 19-300) was equipped to assist the two existing engines in case of emergency and heavy load. The hydraulic system has been employed in AN-24 for braking, steering and wheeling. ANTONOV industries had run its business successfully, as result 1,000 aircrafts were distributed to more than forty countries in Africa, Middle East, Latin America and Asia including Cambodia. Cambodia has used AN-24 since 1980 as part of Russian donation program. Since there was an open sky policy, two private airlines companies-Phnom Penh Airways and President Airlines-have also operated AN-24 for their businesses, which best suite to Cambodian geography and internal airports with short runways.
