FMAIA 58 Pucara

Development: The unusual but effective Pucara was derived from the larger IA 50 Gil (Guarani II) multi-role transport, noted for its slender unswept wings but sharply swept fin and rudder. The first production batch of Gil’s comprised 18 to the Argentine Air Force for communications and seating for up to 15 passengers, four as photo survey aircraft with the

Military Geographic Institute and one as a VIP transport for the President of Argentina. Many others were ordered later, some having ski gear for use in the Antarctic. The smaller IA 58 seats pilot and observer in tandem Martin – Baker ejection seats and is well equipped for all-weather tactical Co-In operations. Deliveries began in 1975 on the first batch of 30 for the Argentine Air Force, with further batches up to a predicted total of 100 being discussed. Interest has been expressed by several other nations in this versatile and cost/ effective aircraft, which can operate from rough strips down to about 2,000ft in length. The Trainer uses the IA 58 airframe restressed to have two turbofan engines on the sides of the fuselage, the twin-wheel main gears retracting forwards into wing pods in the same locations as the engine nacelles on the IA 58. It was expected that this project would lead to a tactical Со-In version, but development has been delayed by inflation.
