Accident

The accident happened at 18:10 Iran Daylight Time (13:40 UTC). The aircraft overran the runway at high speed and crashed outside the airport perimeter, the nose area totally destroyed and resting on its tail. There was no fire. Sixteen people were killed. Among the dead were thirteen crew members and three passengers including Aria CEO Mahmoud Dadpay. There were 137 survivors of the total of 153 people on board.

The aircraft was reported to have skidded off the runway. The cockpit area of the aircraft was destroyed by the impact with the airport perimeter wall. Nineteen people were reported to have been injured in the accident. The weather was good at the time of the accident, with the METAR in force at the time reading "METAR OIMM 241300Z 08014KT CAVOK 34/M03 Q1012 A2989". This translates as, METAR for Mashhad International Airport, issued on the 24th of the month at 13:00 UTC, wind at 14 knots (26 km/h), wind direction 080°; ceiling and visibility OK; temperature 34 °C; dew point −3 °C; altimeter 1012 millibars or 29.89 inches of mercury. The aircraft landed with a crosswind. It landed "long" and overran the end of the runway, hitting a wall located more than 1,100 metres (1,200 yd) further on, which demolished the forward section of the aircraft.

Cause

According to the investigation by the Iranian Civil Aviation Organisation, the approach speed along the glide path was 325 kilometres per hour (200 mph; 175 kn), which was about 50 kilometres per hour (30 mph; 25 kn) more than the recommended speed. Corrective action could have been taken, but the engine reverser and spoiler systems were not used correctly to reduce speed.

As a result of the accident, the Air Operators Certificate of Aria Air was suspended.
