The Romanian IAR 316 Light Utility Helicopter was a locally-built (under license) form of the popular French-made Aerospatiale Alouette III series (SA 316B model). The Alouette III first flew in prototype form on February 28th, 1959 and saw service introduction in 1960, still maintaining an active presence in the skies today (2016). Over 2,000 of the type were eventually produced for a variety of global operators. The Romanian form itself was introduced in 1971 and saw manufacture from 1971 until 1987 with 250 units delivered. These have served in both utility and training roles for their time in the air.
IAR is the Industria Aeronautica Romana aerospace manufacturer of Ghimbav.
Because of its origins in the French design, little was changed in the local Romanian model. As Romania fell under the communist reach during the Cold War decades, the helicopter was modified to support Eastern Bloc weapons and equipment though, in both form and function, there was little separating the two designs - the single engine fit powered a three-bladed main rotor with three-bladed tail rotor, the nose section was wholly glazed over for excellent vision out-of-the-cockpit, and the tricycle undercarriage was fixed in place during flight.
The standard IAR 316 model was finalized with a Turbomeca "Artouste" IIIB series turboshaft engine of 570 horsepower. Maximum speed reached 130 miles per hour with a range out to 335 miles and a service ceiling up to 10,500 feet.
While the original IAR 316 model could be outfitted with a light weapons set, IAR engineers took to refining the product for the attack helicopter role in the IAR 317 "Airfox" offering. For this model the cockpit was completed reworked to include a stepped pilot/gunner arrangement while wing stubs were added to the fuselage sides for management of Anti-Tank (AT) missiles, rocket pods and machine guns. Beyond that, the major structure and components were retained from the original IAR 316. Despite this work, the IAR 317 failed to net any market interest and only a sole prototype was completed.
Beyond operational service with the Romanian Air Force, the IAR 316 was adopted by the Angolan Air Force.
