Description

On 25 October 2017, a Bombardier CRJ-900 (EI-FPD) being operated for SAS in their livery by CityJet under a wet lease contract making a scheduled international passenger flight from Stockholm Arlanda to Turku as SK4236 did not decelerate normally after making a night touchdown on the slush-covered destination runway. It hit runway edge lights and briefly left the runway whilst remaining on the adjacent paved surface before regaining it and making a counter clockwise rotation and coming to a stop on it but near the end of the runway pointing towards the landing threshold. It was decided that an emergency evacuation was not necessary and after the crew had recovered from their landing experience, the aircraft was subsequently taxied to the apron for passenger disembarkation. There were no injuries to any of the 92 occupants but all four mainwheel tyres were damaged beyond continued use as a result of the combination of prolonged locked wheel skidding and the collision with runway edge lighting.

Investigation

An Investigation was carried out by the Finnish Safety Investigation Authority (SIAF). Relevant data from the FDR and CVR were downloaded and snapshots of FADEC data were also obtained. Exceptionally, the Investigation did not record the experience of the two pilots.
