The Australian Transport Safety Bureau (ATSB) today released its preliminary factual report into the Emirates A340-500 tail-strike that occurred on 20 March at Australia's Melbourne Airport.
The report said that soon after the tail-strike happened "the crew noticed that an incorrect weight had been inadvertently entered into the laptop when completing the take-off performance calculations prior to departure."
"The performance calculations were based on a take-off weight that was 100t below the actual take-off weight of the aircraft."
"The result of that incorrect take-off weight was to produce a thrust setting and take-off reference speeds that were lower than those required for the aircraft's actual weight."
ATSB says "damage to the aircraft included abraded skin to the rear, lower fuselage and damage to the rear pressure bulkhead."
