Summary

At 1503 Coordinated Universal Time (UTC) on 9 December 2004, the pilot in command of an Airbus Industrie A330-301 aircraft, registered VH-QPC, commenced the takeoff from Changi Airport, Singapore on a scheduled regular public transport service to Darwin, NT. The pilot in command reported that the aircraft felt nose heavy during rotation, but that after the aircraft was trimmed, a more normal feel was restored. Following the flight it was found that the aircraft’s take-off centre of gravity (CG) was forward of the manufacturer’s forward limit.

The investigation found that:

  • there had been a corruption of the aircraft’s weight and balance data within the international load control system
  • the error did not manifest itself until the aircraft was used on an international service and the aircraft’s weight and balance was calculated using the corrupted data in the international load control system
  • the Singapore load controllers did not carry out a check of the basic aircraft’s data as they were required to do by the operator
  • the flight crew did not carry out a check of the basic aircraft data as they were required to do by the operator.

The operator made a number of changes to procedures that will enhance the existing organisational and individual risk controls affecting A330 aircraft loading. The operator will also introduce a single load control system from March 2007, which will minimize the likelihood of a recurrence of the data corruption event leading to this incident.
