Iran Air

While descending to Tehran-Mehrabad Airport, the crew was informed about the poor weather conditions at destination with snow falls, low visibility and a 20 knots tailwind. The crew decided to divert to Isfahan-Shahid Beheshti Airport. On approach, the crew encountered limited visibility due to foggy conditions. The aircraft struck the ground, lost its undercarriage and slid for almost one km before coming to rest in a desert area located 8 km short of runway 26. All 113 occupants escaped uninjured while the aircraft was damaged beyond repair.

The crew departed Tehran-Mehrabad Airport at 1233LT on a training flight to Rasht. Following 14 touch-and-go manoeuvres completed successfully, the crew approached the airport but forgot to lower the landing gear. The aircraft landed on its belly and slid on runway 09 for a period of 30 seconds and on a distance of 2,100 metres. Despite the situation, the crew decided to take off again and continued to climb when the rear fuselage caught fire. The crew declared an emergency, extended the undercarriage manually and was cleared to land on runway 09. On final approach, the aircraft became unstable, lost height and crashed in a field located 5 km short of runway. Four crew members were killed while three others were injured. The aircraft was destroyed. §

Flight IR451 arrived at Bandar Abbas (BND) from Tehran (THR) at 08:40. The Airbus A300 was to continue to Dubai (DXB) as flight IR655. Prior to departure the crew received an enroute clearance to Dubai via the flight planned route A59 and A59W at FL140. The flight took off from runway 21 at 10:17 hours and climbed straight ahead. Two minutes later, the crew reported leaving 3500 feet for FL140 on Airway A59, estimating MOBET at 06:53 UTC (10:23 Iran time). At 10:24:00 the aircraft passed MOBET out of FL120. At 10:24:43 two Airbus was hit by surface-to-air missiles. The tail and one wing broke off as a result of the explosions. Control was lost and the aircraft crashed into the sea. The missiles were fired by the US Navy cruiser USS Vincennes. It was operating in the area together with the frigates USS Elmer Montgomery and USS John H. Sides. They were to protect other ships in the area. At about the time the Airbus took off, the radar aboard the USS Vincennes picked up a brief IFF mode 2 response, which led to the mistaken identification of the Airbus as a hostile F-14 aircraft. The USS Vincennes issued 7 challenges on the Military Air Distress (MAD) frequency 243 MHz, addressed to 'Iranian aircraft', 'Iranian fighter' or 'Iranian F-14'. These messages were followed by three challenges on the IAD (International Air Defence) radio frequency. Due to increasing tension in the area - on May 17, 1987 an Iraqi Mirage had attacked USS Stark - all aircraft in the area had to monitor 121.5 Mhz: the International Air Defence - IAD radio frequency. There was no response. Meanwhile radar operators were monitoring the Aegis screens. They reported that the incoming plane was descending with an increasing speed. In fact, the Airbus was climbing. Considering itself and USS Montgomery under aggression, USS Vincennes took the ultimate decision to launch missiles against the perceived hostile target at 10:24:22.
It remains uncertain whether the IR655 flight crew (only able to monitor the IAD, not the MAD frequencies) would have been able to rapidly identify their flight as the subject of the challenges made by the USS Vincennes.

The aircraft was taxiing and preparing for takeoff at Shiraz Airport when it was hit by an air-to-surface missile shot by the pilot of an Iraqi fighter who was attacking the airport. The B737 caught fire and was partially destroyed by fire. Three passengers were killed, 30 other occupants were injured and 47 unhurt.

Two mechanics took over the airplane to complete a high-speed taxi check following maintenance. While taxiing, the airplane went out of control and veered off taxiway, causing the left main gear and the nose gear to collapse. The airplane came to rest on soft ground and was damaged beyond repair while both occupants escaped uninjured.

On the day of the accident, Iranian air traffic controllers went on strike, which led to hundreds of domestic flights being cancelled. At 1600LT the strike was interrupted and flights resumed. At 1740LT, the airplane departed Mashad Airport on schedule service IR291 to Tehran-Mehrabad Airport with 120 passengers and a crew of eight on board. At 1852LT, ATC based at Tehran-Mehrabad Airport cleared the crew for a direct approach to runway 29. At 1905LT, the dispatcher instructed the crew to take a 360° heading to reach the non-directional beacon of Varamin. On approach, the copilot informed the captain that the VORTAC was giving a wrong radial course but the captain failed to respond to this message. At 1911LT, while descending in limited visibility due to night, snow falls and foggy conditions, the airplane struck the slope of a mountain located in the Alborz Mountain Range. The wreckage was found few hours later in a snow covered terrain about 29 km north of Tehran Airport. The aircraft disintegrated on impact and none of the 128 occupants survived the crash.

On final approach to Bandar Abbas Airport, the airplane was too low for undetermined reason when it struck the ground and came to rest in flames few dozen yards short of runway. Eleven passengers were killed while 17 other occupants were evacuated. The aircraft was destroyed.

The aircraft landed hard for unknown reason. On touchdown, the left main gear collapsed and the aircraft veered off runway to the left before coming to rest. There were no casualties but the aircraft was written off.

Suffered an accident at Isfahan Airport. There were no injuries.
