MD83 / AT76, Isfahan Iran, 2018

MD83 / AT76, Isfahan Iran, 2018

Summary

On 21 January 2018, a McDonnell Douglas MD-83 which had just landed on one of the two parallel runways at Isfahan, entered the roll out end of the other one and began taxiing on it in the opposite direction to an ATR72-600 which was about to touch down at the other end of the same runway. The Investigation found that the MD83 had failed to follow its taxi clearance but also that the TWR controller involved had failed to instruct the conflicting ATR-72 to go around, a requirement that was not optional despite the 4397 metre runway length.

Description

On 21 January 2018, a McDonnell Douglas MD-83 (UR-CQC) being operated by Bukovyna Airlines on a domestic passenger flight from Mashhad to Isfahan for ATA Airlines as TBZ5704 and an ATR72-600 (EP-ITH) being operated by Iran Air on a scheduled domestic passenger flight from Ahwaz to Isfahan as IRA3366 came into conflict on runway 26L after the MD-83 entered the far end of the runway and began backtracking as the ATR72 was on short final to land on it. The ATR72 did not go around and was able to exit after landing before reaching the MD-83.

Investigation

An Investigation was carried out by the Aircraft Accident Investigation Board (AAIB) of the Iran Civil Aviation Organisation (CAO). Both aircraft continued in service after the event and consequently relevant CVR and FDR data was overwritten and no equivalent data was available, however recorded ATC data was available.

It was noted that the 34 year-old Captain and the 30 year-old First Officer of the MD-83 were both Iranian nationals with their Iranian licences and type rating endorsed by the Ukrainian authorities as the State of Registry of the aircraft involved.
