CRJ900 hydroplaned and spun on Turku runway slush

Investigators have determined that a CityJet-operated Bombardier CRJ900 landed in a tailwind on a contaminated runway, on which it hydroplaned and spun more than 180° before coming to rest.The crew of the aircraft, conducting a service for SAS to Turku on 25 October last year, had opted to use runway 26  despite the tailwind owing to a lack of ILS on the opposite-direction runway 08.Although the CRJ900 landed at 148kt in the correct zone, the touchdown was relatively hard at 1.95g. The captain had selected reverse thrust immediately after touchdown but the aircraft’s rebound effectively inhibited this system, and the engines remained at reverse idle.
