E190, Oslo Norway, 2010

Summary

On 23 October 2010, an Embraer 190 commenced its night rolling takeoff from runway 01L at Oslo with the aircraft aligned with left runway edge lights instead of the lit centreline before correcting to the runway centreline and completing the takeoff and flight to destination. Engine damage caused by ingestion of broken edge light fittings, which was sufficient to require replacement of one engine before the next flight, was not discovered until after completion of an otherwise uneventful flight. Tyre damage requiring wheel replacement was also sustained. The Investigation concluded that inadequate CRM had been a Contributing Factor.

Description

On 23 October 2010, an Embraer 190LR (OH-LKL) being operated by Finnair on a scheduled international passenger flight from Oslo to Helsinki as FIN658M commenced take off from Runway 01L at Oslo in good night visibility when aligned with the runway edge lights instead of the runway centreline lights and then corrected onto the centreline – all without ATC awareness – and completed the takeoff. ATC were subsequently advised that collision with lights may have occurred and damage was then found. After an uneventful flight, it was found that the right engine had been sufficiently damaged by ingestion of broken light debris to require its removal for repair. Debris-caused tyre damage requiring main and nose gear wheel replacement was also found.
