Narrative:On September 18, 2014 a Boeing 737-800 started its take-off at Groningen Airport Eelde for a flight to Rotterdam The Hague Airport. During the take-off roll the pilots became aware that the acceleration was less than expected. The take-off was continued. The take-off weight used for the performance calculation was 10 tonnes too low due to a miscalculation of the take-off weight on the take-off data card (bugcard) by the flight
crew. As a consequence the selected take-off thrust was lower than required. Approximately 60 metres before the end of the runway the aircraft became airborne.
Direct causes
The insufficient thrust setting was the consequence of a miscalculation on the bugcard.
The errors could propagate because there were no adequate crosschecks in place to detect the errors. A crosscheck regarding the TOW on the bugcard was lacking.
Contributing factors
• the large number of calculations, data entries and data transfers;
• the lack of guidelines regarding which source should be used for the weight in the take-off performance calculation.
• lack of guidelines regarding the purpose of the bugcard, leading to it being used for a calculation whilst it is meant solely as a reference chart.
