Détails:A Boeing 727-86 passenger jet, registered EP-IRD, was destroyed in a CFIT accident 29 km N of Tehran, Iran. All 120 passengers and eight crew members were killed. The airplane operated on a flight from Mashhad Airport (MHD) to Tehran-Mehrabad Airport (THR).
The aircraft had been cleared for an ILS approach to runway 29 at 18:52 hours. At 19:11 the aircraft crashed in the Elburz Mountains north of Teheran.
The investigation revealed that the pilot did not follow the ATS route, but proceeded straight to Mehrabad Airport. About six minutes before impact ATC asked the pilot to make a 360 deg turn over Varamin Non-directional Radio Beacon (NDB). The pilot made this 17nm to the north without advising ATC. On approach the copilot pointed out VORTAC radial crossing on wrong track, but the pilot did not react.
Probable Cause:
PROBABLE CAUSE: Inoperable ILS and ground radar.
