Confidence Rating: Accident investigation report completed and information captured
The performance data for TUI flight BY7226 were calculated incorrectly, with 38 females accounted for in the weight as child. Consequently, the weight error between load sheet and actual take-off weight was 1244kg and the take-off was conducted with slightly less than required thrust and calculated speeds 1kts less than required.The flight was uneventful.
The discrepancy was due to a reservation system software update that incorrectly allocated passengers with the suffix Mrs. to a child. Several other flights of TUI Airways departed that day with incorrect weight figures.

AAIB Conclusion:
A flaw in the IT system used by the operator to produce the load sheet, meant that an incorrect takeoff weight was passed to the flight crew. As a result, the aircraft departed with a takeoff weight 1,244 kg more than stated on the load sheet. An upgrade of the system producing load sheets was carried out to prevent reoccurrence.
