13-582: As of 2022, there were 477 MFI-15/17/395 in use, making it one of the most commonly used training aircraft in the world. The MFI-15 Safari and MFI-17 Supporter were created from Saab's adaptation of the MFI-9 Junior for basic training for civil and military operators. In 1968 Saab began work on its MFI-15, based on the MFI-9 but with some design changes. Foremost of the changes in the Saab built MFI-15 prototype

26-504: Is a family of four-cylinder, air-cooled, horizontally opposed, piston aircraft engines that produce 100 to 135 hp (75 to 101 kW), derived from the earlier O-233 engine. Well-known designs that use versions of the O-235 included the Cessna 152 , Grumman American AA-1 series, Beechcraft Model 77 Skipper , Piper PA-38 Tomahawk , American Champion Citabria , Piper Clipper , and

39-444: Is a large family of naturally aspirated, 320 cu in (5.2 L) air-cooled, horizontally-opposed four-cylinder , direct-drive engines produced by Lycoming Engines . Introduced in 1953, it is commonly used on light aircraft such as the Cessna 172 and Piper Cherokee , and remains in production as of 2024. Different variants are rated for 150 or 160 horsepower (112 or 119 kilowatts). The O-320 family of engines includes

52-434: The carbureted O-320, the fuel-injected IO-320, the inverted mount, fuel-injected AIO-320 and the aerobatic , fuel-injected AEIO-320 series. The LIO-320 is a "left-handed" version with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine . The first O-320 (with no suffix) was FAA certified on 28 July 1953 to CAR 13 effective 5 March 1952; this same engine

65-545: The H2AD model. All other 160 hp (119 kW) 0-320s are approved for 91 AKI. Airframe approval is also necessary to use automotive gasoline in any certified aircraft. The factory retail price of the O-320 varies by model. In 2010 the retail price of an O-320-B1A purchased outright was USD$ 47,076 Data from TYPE CERTIFICATE DATA SHEET NO.

78-645: The MFI-395 in 1995 was initiated by the then-managing director of AMF, Air Cdr Muhammad Younas. The aircraft was built by upgrading the MFI-17 with an advanced 260 hp engine, electrical instruments, dual flight control systems and a Bendix RSA fuel injection system. As of 2022, there were 477 MFI-15/17/395 in use, making it one of the most commonly used training aircraft in the world. Fitted with an American 260 hp engine, cockpit air conditioning, electrical instruments, and electric/manual elevator and rudder trim,

91-695: The aircraft has been developed to meet FAR part 23 certification in normal, utility and aerobatics categories. It has a spacious side-by-side cockpit allowing good contact between the pilot and the co-pilot/observer or between the student and the instructor . The aircraft has been involved in a few notable crashes: Data from Jane's All the World's Aircraft 1988–89, Jane's All The World's Aircraft 1993–94, Pakistan Aeronautical Complex, Jane's All The World's Aircraft 2003–2004 General characteristics Performance Armament Related development Lycoming IO-320 The Lycoming O-320

104-521: The late 1970s after about 250 Safaris and Supporters had been built, mostly for civil customers. Pakistan has taken delivery of 18 Supporters, while 92 have been assembled locally by PAC from knocked down kits and a further 149 were built locally by PAC. It is named Mushshak ("Proficient") in Pakistani service. In 1981, Pakistan acquired sole manufacturing rights to the Supporter. The development of

117-410: The piston pins, cylinder walls and gears are all lubricated by spray. The oil system is pressurized by an accessory-drive mounted oil pump. A remotely mounted oil cooler is used, connected to the engine by flexible hoses. The 150 hp (112 kW) versions of the carbureted O-320, are approved for the use of 87 AKI automotive gasoline . Models with 9.0:1 compression ratio are not approved, such as

130-523: The smaller engines, but produces more power with the bore increased to 5.125 in (130 mm). The design uses hydraulic tappets and incorporates the provisions for a hydraulically controlled propeller installation as well. The controllable-pitch propeller models use a different crankshaft from those intended for fixed-pitch propellers. The O-320 uses a conventional wet sump system for lubrication. The main bearings, connecting rods, camshaft bearings, tappets and pushrods are all pressure lubricated, while

143-705: Was in February 1971. Sold as the MFI-15 Safari, most went to civil customers, however Sierra Leone and Norway took delivery of Safaris for military pilot training. To improve the Safari's military market appeal, Saab developed the MFI-17 Supporter, fitted with six underwing hardpoints for light and practice weaponry, giving it weapons training and light COIN capabilities. First flight was on July 6, 1972. Important were Denmark and Zambia. Production ended in

156-615: Was later re-designated, without change, as the O-320-A1A. The first IO-320 was certified on 10 April 1961, with the AIO-320 following on 23 June 1969 and the first aerobatic AEIO-320 on 12 April 1974. The LIO-320s were both certified on 28 August 1969. The O-320 family of engines externally resembles the Lycoming O-235 and O-290 family from which they were derived. The O-320 shares the same 3.875 in (98 mm) stroke as

169-533: Was the 120 kW (160shp) Lycoming IO-320 piston engine. Like the MFI-9, the MFI-15 retained the unusual braced, mid-mounted and slightly forward-swept wing and rearward-hinged canopy, offering good all-around vision. The prototype made its maiden flight on June 11, 1969. Follow-up testing of the MFI-15 resulted in a more powerful IO-360 engine, while the horizontal tail was relocated to prevent it being damaged by thrown up debris. The first flight of this modified form
