Narrative:
An Iran Air Boeing 727 passenger jet was damaged beyond repair in an accident about 8 km from Urmia (Orumiyeh) Airport (OMH), Iran. There were 96 passengers and nine crew members on board. The airplane operated on flight IR277 from Tehran-Mehrabad Airport (THR) to Urmia (Orumiyeh) Airport (OMH). It left Tehran at 18:15, after a delay of over two hours due to severe weather at the destination.

The effect of a combination of bad weather and cockpit crews' failure to deal with the situation is the major cause of the accident.

Contributing factors:
- The old technology of aircraft systems
- Absence of a suitable simulator for adverse weather conditions
- Failure to correctly execute the operating instructions for go around
- Inadequate cockpit management (CRM)
