On 14 January 2013, selection of the power levers to ground idle after an ATR 72-200 touchdown at Copenhagen produced only one of the two expected low pitch indications. As the First Officer called 'one low pitch' in accordance with SOP, the Captain selected both engines into reverse. He was unable to prevent the resultant veer off the runway. After travelling approximately 350 metres on grass alongside the runway as groundspeed reduced, the runway was regained. A propeller control fault which would have prevented low pitch transition on the right engine was recorded but could not subsequently be replicated.
Description
On 14 January 2013, an ATR72-212 (E7-AAD) being operated on a passenger flight from Sarajevo to Copenhagen left the side of the runway at high speed shortly after touchdown on runway 22L at Copenhagen in day Visual Meteorological Conditions (VMC). After travelling on the grass and decelerating for approximately 350 metres, the aircraft regained the runway. After a visual inspection by the airport Rescue and Fire Fighting Services to confirm that no obvious damage had been sustained, the aircraft was taxied to the terminal. The aircraft was subsequently confirmed to be undamaged and there were no injuries to the 42 occupants.

Investigation
An Investigation was carried out by the Danish AIB. It was noted that both pilots had similar and significant experience, almost all of it gained on the ATR-72 in both cases. The aircraft commander had been PF for the landing.
