Bergen - Skien

The aircraft was on its way to Skien with a crew of two and 11 passengers. During the flight, ice was observed on the aircraft’s wings, but the ice was considered to be too thin to be removed. During descent towards runway 19 at Geiteryggen the aircraft’s ground proximity warning system (GPWS) sounded a total of three times. The aircraft was then in clouds and the crew did not have visual contact with the ground. The warnings, combined with somewhat poorly functioning crew coordination, resulted in the crew forgetting to actuate the system for removing ice from the wings. The subsequent landing at 1828 hrs was unusually hard, and several of the passengers thought that the aircraft fell the last few metres onto the runway. The hard landing caused permanent deformation of the left wing so that the left-hand landing gear was knocked out of position, and the left propeller grounded on the runway. The crew lost directional control and the aircraft skewed to the left and ran off the runway. The aircraft then hit a gravel bank 371 metres from the touchdown point. The collision with the gravel bank was so hard that the crew and several of the passengers were injured and the aircraft was a total loss. It was dark, light rain and 4 °C at Geiteryggen when the accident occurred. The wind was stated to be 120° 10 kt. The investigation shows that it is probable that ice on the wings was the initiating factor for the accident. The AIBN has not formed an opinion on whether the ice resulted in the high sink rate after the first officer reduced the power output of the engines, or whether the aircraft stalled before it hit the runway. Investigation has to a large extend focused on the crew composition and training. A systematic investigation of the organisation has also taken place. In the opinion of the AIBN, the company has principally based its operations on minimum standards, and this has resulted in a number of weaknesses in organisation, procedures and quality assurance. These conditions have indirectly led to the company operating the route Skien – Bergen with a crew that, at times, did not maintain the standard that is expected for scheduled passenger flights. The investigation has also revealed that procedures for de-icing of the aircraft wings could be improved.
