The Accident Investigation Board Denmark concluded that a March 2011 hard landing accident involving a DHC-8 in Greenland was caused by a breakdown in CRM during the approach phase, which resulted in an unstabilized approach being flown.

On March 4, 2011, a de Havilland Canada DHC-8-106 passenger plane of Flugfélag Íslands – Air Iceland operated on a flight from Kulusuk Airport to Godthåb/Nuuk Airport  in Greenland. The weather was adverse with winds from 170° at a speed of 24 knots with a maximum of 43 knots and  a visibility of 4,000 meters in light snow.

The flight crew made visual contact with the runway and decided to deviate to the right (west) of the offset Localizer (LLZ) to runway 23. The flight continued towards the runway from a position right of the runway centerline. As the aircraft approached runway 23, it was still in the final right turn over the landing threshold. The aircraft touched down on runway 23 between the runway threshold and the touchdown zone and to the left of the runway centerline. The right main landing gear shock strut fuse pin sheared leading to a right main gear collapse. The aircraft skidded down the runway and departed the runway to the right. There were no injuries to the 34 occupants, but the airplane sustained substantial damage.

The investigators concluded that the strong winds and moderate to severe orographic turbulence from the surrounding mountainous terrain increased the flight crew load during the approach. The flight crew had difficulties of maintaining stabilized approach parameters and most likely suffered from task saturation and information overload. Important low altitude stabilized approach parameters like airspeed, bank angle and runway alignment were not sufficiently corrected.

The flight crew was solely focused on landing and task saturation mentally blocked a decision of going around.
