An Iran Air Boeing 727-200, registration EP-IRR performing flight IR-742 from Moscow Sheremetyevo (Russia) to Tehran Imam Khomeini (Iran) with 94 passengers and 19 crew, was on approach to Tehran's Imam Khomeini Airport around 15:20L (11:50Z) when the crew did not receive a down and locked indication for the nose gear and aborted the approach. Following unsuccessful troubleshooting the crew decided to divert to Tehran's Mehrabad Airport where a low approach confirmed the nose gear was not extended. The crew subsequently performed a landing without the nose gear on runway 29L at about 16:00L (12:30Z) and came to a stand still on both main gear and the nose of the aircraft. The aircraft was evacuated, no injuries occurred. The pilot of this flight was captain Hooshang Shahbazi.
