Atlantic Airways Flight 670 was a crash following a runway overrun of a British Aerospace 146-200A at 07:32 on 10 October 2006 at Stord Airport, Sørstokken, Norway. The aircraft's spoilers failed to deploy, causing inefficient braking. The Atlantic Airways aircraft fell down the steep cliff at the end of the runway at slow speed and burst into flames, killing four of sixteen people on board.
The flight was chartered by Aker Kværner from Stavanger Airport, Sola via Sørstokken to transport its employees from there and Stord to Molde Airport, Årø. An investigation was carried out by the Accident Investigation Board Norway (AIBN). It was not able to find the underlying cause of the spoiler malfunction. However, it found that, when the captain selected the emergency braking, the anti-lock braking system was disabled. This selection caused the brakes to completely lock, resulting in reverted rubber hydroplaning, a condition in which the tires became extremely hot due to frictional forces, and the water on the damp runway surface evaporated to steam, effectively causing the tires to float on a cushion of steam over the runway surface, greatly reducing braking action. This situation was made worse with a minimal runway end safety area and lack of grooves in the runway surface.
