Aviones. It is a low-wing twin-turboprop all-metal monoplane with retractable
landing gear, capable of operating from unprepared strips when operationally
required. The type saw action during the Falklands War and the Sri Lankan Civil
War.
The unswept cantilever wings have 7 degrees of dihedral on the outer panels and
are fitted with slotted trailing-edge flaps. The IA-58 has a slender fuselage,
with a tandem cockpit arrangement; the crew of two is seated under the upward
opening clamshell canopy on Martin-Baker Mk 6AP6A zero/zero ejection seats and
are provided with dual controls and good visibility, at least in the lateral and
relatively high speed, higher than the American OV-10 Bronco, another COIN
aircraft. On the other hand, the IA 58 has no cargo bay inside the fuselage as
requested for the American aircraft.
Armour plating is fitted to protect the crew and engines from ground fire. The
aircraft is powered by a pair of Turbomeca Astazou engines, driving sets of
three-bladed Ratier-Forest 23LF propellers; the propellers are also capable of
being used as air brakes.
directly comparable with the layout used in the German Bf 110. It consists of
two Hispano 804 20 mm cannons mounted under the cockpit with 270 rounds each and
four 7.62 mm Browning FN machine guns mounted on the sides of the fuselage with
900 rounds each. Three hardpoints are fitted for carrying external stores single
or in clusters (as example up to six bombs under the fuselage or two rockets
under each wing) such as bombs, rockets or external fuel tanks, with one of
1,000 kg (2,200 lb) capacity mounted under the fuselage and the remaining two,
of 500 kg (1,100 lb) capacity beneath the wings. Total external weapons load is
limited to 1,620 kg (3,570 lb). Onboard armaments are aimed by a simple
reflector sight.
