Report on aircraft incident at Oslo airport, Gardermoen 25 May 2015 involving Boeing 737-800, LN-RCZ, operated by Scandinavian Airlines System DK-NO-SE
Aviation report 2016/06
LN-RCZ (SAS4425) landed on runway 01L in tailwind conditions and rain. The runway was shortened from 3 600 m to 1 928 m due to asphalt resurfacing. The last 300 m of the runway surface consisted of concrete. A published NOTAM informed that the concrete surface was "slippery when wet". The aircraft landed after being stabilized at 1 000 ft and 500 ft. The flight crew on LN-RCZ was unable to achieve sufficient deceleration after landing and the aircraft departed the runway (Runway Excursion-Overrun). The aircraft came to rest approx. 50 m into the Runway End Safety Area (RESA). After colliding with runway light fixtures, the aircraft sustained minor damage. There were no injuries.
It is the AIBN’s view that multiple factors contributed to the fact that SAS4425 was unable to stop before the runway end. The flight crew decided to land with a landing configuration not suitable for the actual weather and runway conditions, in addition to late engagement of full “thrust reversers” after landing.
Several crew on previous flights had reported very slippery conditions on the last part of the runway. The airport operator had not, to a sufficient extent, assessed the risk of the combination of shortened runway, poor friction during precipitation and tailwind conditions.
Based on the measures implemented after the incident for both the airline and the airport operator the AIBN does not issue any safety recommendations.
