Design

edit

Originally designed by Radu Manicatide and fine-tuned by the Uzinele de Reparatii Material Volant-3 (URMV-3) of the Industria Aeronautică Română,[2] the IAR 814 was a three-seat low-wing monoplane of mixed construction, primarily designed as a trainer, but could also serve as a transport. Power was supplied by two Walter Minor 6-III engines, and the aircraft was also equipped with blind-flying instrumentation and radios. The main wheels of the tail-wheel undercarriage retracted into the rear of the engine nacelles.[3][1] The two prototypes and 8 production aircraft were registered as YR-MRA to YR-MRJ.[1]

Operational history

edit

The IAR-814 was designed with long-distance flying in mind and established a long-distance world record in class C-1d, (contemporary FAI class), on 14–15 October 1961; flying a distance of 4,462.87 km (2,773.10 mi; 2,409.76 nmi) over a circuit between Băneasa-Alexeni Airfield-Strejnic-Băneasa, piloted by Octavian Băcunu and Vladimir Viscun, in a time of 20 hours 41 minutes at 216 km/h (134 mph; 117 kn).[3]
