aircraft in total were planned to be built; 20 of them were to be acquired by the Iranian government for border patrol and surveillance. On 9 November 2010, during his opening speech of the Kish air show, the Iranian transport minister announced that 14 IrAn-140 aircraft had so far been completed; the first six entered commercial service on 19 February 2011. However, after the Sepahan Airlines Flight 5915 crash, An-140 operations were banned by the CAO of Iran, with all remaining Iranian-registered examples grounded. On 23 August 2014 Brigadier General Hossein Dehqan, Iran's Minister of Defence, announced full compliance of IrAn-140 airplanes with ICAO requirements and that the aircraft is certified by Iran's Civil Aviation Organisation. Operators As of December 2022, 23 An-140 and further 10 HESA IrAn-140 have been built for airline and government service, including prototypes. Of these 33 aircraft, only 9 remain in active service. While 20 further aircraft are stored, four An-140 were lost in accidents. Accidents and incidents Since its introduction in 2002, the Antonov An-140 has been involved in five accidents and incidents, including four hull-loss accidents, resulting in 111 occupant fatalities. Of the aircraft lost, three were HESA IrAn-140 aircraft built in Iran from knock-down kits supplied by Antonov. On 23 December 2002, Aeromist Kharkiv Flight 2137, an An-140 (UR-14003) carrying many of Ukraine's top aviation designers and engineers, crashed into a mountainside as it was preparing to land at Isfahan, Iran, killing all 44 on board. The delegation was to have attended the inauguration ceremonies for the first HESA IrAn-140 airframe. The probable cause was controlled flight into terrain (CFIT) due to incorrect use of the cockpit satellite navigation system. On 12 August 2005, a Safiran Airlines HESA IrAn-140 diverted to Arak Airport due to an engine failure. During landing, the aircraft overran the runway and was badly damaged. There were no fatalities. The cause of the engine failure appeared to be technical problems with the fuel control unit. The airframe was eventually repaired in the early 2010s and is to be used by HESA as a test bed for the future versions of the aircraft. After the Arak incident, Safiran Airlines returned its two remaining examples to HESA. On 23 December 2005, Azerbaijan Airlines Flight 217, an An-140-100 (4K-AZ48), crashed into the Caspian Sea at CA 22:40, killing all 23 passengers and crew on board.
