The Aeronautica Militara selected the P.Z.L. P.11 for the re-equipment of its fighter element in 1934, and a small series of I.A.R.14s was also ordered that year for evaluation purposes. Flown in 1933, the I.A.R.14 was essentially similar to the I.A.R.13, but reverted to the Lorraine 12Eb engine, which had the advantage of being licence-built by I.A.R. The fuselage of the I.A.R.14 was redesigned, the turnover pylon was incorporated in a fairing aft of the cockpit, shorter-span, broad-chord ailerons were introduced, the vertical tail was redesigned and the span of the horizontal surfaces was increased, their inverted- Vee type bracing struts giving place to parallel struts. Armament remained a pair of 7.7mm Vickers guns.
The last IAR-14 fighter, No 20, manufactured in series at IAR, made its first flight on September 2, 1939, five years after the order was placed by the Romanian government, and was still flown during the war years.
The twenty I.A.R.14s delivered to the Aeronautica Militara in 1934 were utilised, after service evaluation, in the fighter training role.
