Remarks: Romanian designed single-seat agricultural aircraft. In 1981, the IAR-827 prototype was re-engined with a Pratt & Whitney Canada PT6A turboprop and redesignated first as the IAR-827TP and later as the IAR-828. His first flight was on September 7th 1981. Plans to produce the aircraft either with the Pratt & Whitney Canada engine or a Walter 601 never materialised. This is the only IAR-828 ever built, registered to Romania Air Force.
