Executive Summary:The airline company was operating a series charter flight from Salzburg Airport in Austria to Stockholm/Arlanda Airport, with an intermediate stop at Göteborg/Landvetter Airport. In Göteborg 59 passengers disembarked while the remaining 121 remained seated in the cabin. No new passengers were taken on board.

According to the loadsheet that the pilots received prior to the continued flight to Stockholm the passengers were evenly distributed in the cabin and the mass and balance limitations in force were met.

At the start, when the aircraft was approaching 80 knots and before V1 had been reached, the co-pilot, who was the flying pilot, noted that the aircraft’s nose was lifting spontaneously without him moving the control column. He reported this to the commander who took over the control and aborted the takeoff.

The pilots and the SAS-personnel later discovered that the particulars in the loadsheet concerning the distribution of passengers in the cabin did not tally with where the passengers were actually sitting.

The investigation has noted shortcomings in the routines and computerised systems used for the production of loadsheets. This resulted in that the takeoff was commenced with a centre-of-gravity position at more than 1/4 aft of the certified CG span.

The incident was caused by shortcomings in the routines and computer systems used in the production of loadsheets.
