Australian investigators are looking into two instances of performance data error involving Tigerair Australia Airbus A320 flights in the space of two weeks.

The first occurred at Hobart on 15 February when, according to French investigation authority BEA, the crew “inadvertently failed” to program performance data into the flight-management computer before departure.

BEA has not disclosed any further preliminary details about the incident beyond stating that it involved an A320 registered VH-VNQ, which is part of the Tigerair Australia fleet.

The authority has, however, listed a second incident – involving another of the carrier’s A320s (VH-VNJ) – which occurred on 3 March at Sydney.

BEA says the aircraft departed for Perth with a flight plan which indicated planned trip fuel burn of 9,000kg.

But after the aircraft landed in Perth, analysis determined that 11,000kg of fuel had been consumed.

“Post-flight review of the flight plan identified [that] passenger weights had not been entered in the fuel-burn calculation,” says BEA, citing notification from Australian counterparts.

Australian investigators have been particularly active in drawing attention to the issue of incorrect data entry during flight preparations.
