On 13 August 2016, an Airbus A320 departed the side of the runway at low speed during takeoff from Tehran Mehrabad and became immobilised in soft ground. The Investigation found that the Captain had not ensured that both engines were simultaneously stabilised before completing the setting of takeoff thrust and that his subsequent response to the resulting directional control difficulties had been inappropriate and decision to reject the takeoff too late to prevent the excursion. Poor CRM on the flight deck was identified as including but not limited to the First Officers early call to reject the takeoff being ignored.
