The Antonov An-148 (Ukrainian: Антонов Ан-148) is a regional jet designed and built by Antonov of Ukraine. Development of the aircraft was started in the 1990s, and its maiden flight took place on 17 December 2004. The aircraft completed its certification programme on 26 February 2007. The An-148 has a maximum range of 2,100–4,400 km (1,100–2,400 nmi; 1,300–2,700 mi) and is able to carry 68–85 passengers, depending on the configuration.
The Antonov An-158 is a stretched fuselage version of the aircraft, accommodating up to 100 passengers.
The An-148 aircraft is a high-wing monoplane with two turbofan jet engines mounted in pods under the wing. This arrangement protects the engines and wing structure against foreign object damage. A built-in autodiagnosis system, auxiliary power unit, and the wing configuration allow the An-148 to be used at poorly equipped airfields. Flight and navigation equipment features five 15 by 20 cm (5.9 by 7.9 in) liquid crystal display panels built by Russia's
Aviapribor and a fly-by-wire system, which enables the An-148 aircraft to operate day and night, under instrument flight rules and visual flight rules weather conditions on high-density air routes. Similar to the Boeing 737, the main landing gear rotates into the belly of the aircraft when in flight, with partial doors covering the legs, and the sides of the tires remaining exposed. Built-in entrance stairs enable boarding and disembarking the aircraft without extra ground equipment. The manufacturer claims high fuel efficiency of the Motor Sich D-436-148 engines.
