Since 2009 an extensive upgrade of the avionics and major overhaul of the airframes has been carried out by the FAA and FAdeA, creating the IA-58D Pucará Delta. The avionics for the cockpit will be as close as possible to the FMA IA-63 Pampa Phase II. Some of the updated components will include a new set of communications hardware, DME, ELT, IFF, GPS, EADI, EHSI, RWR, HUD, DEFA 554 cannon and new powerplant PT6A-62 950shp instead of the original Turbomeca Astazou. The overhaul will keep Argentinian Pucarás active until 2045. Bureaucratic and economic issues are delaying the conversion of the entire fleet. The Uruguayan Air Force also showed interest on the maintenance, repair, and overhaul (MRO) program and installation of new engines offered by FAdeA.
