Lufthansa's decision to change an engine on its first Airbus A380, in response to the Qantas incident, has partly been driven by the fact that the powerplant was an early production example.
The airline has opted to change two Rolls-Royce Trent 900s on the same A380, registered D-AIMA, but only one change is directly linked to the precautionary measures which followed the in-flight disintegration on a Qantas jet.
Sources familiar with the process state that one engine on the Lufthansa aircraft was from a "former production cycle", indicating that the other three powerplants had already undergone a change before being fitted.
The aircraft in question, serial number 38, was delivered to the carrier in mid-May this year.
Lufthansa states that it will change the engine when it is able to secure a spare powerplant, but will continue to operate the aircraft in the meantime in accordance with precautions issued by Airbus, Rolls-Royce and the European Aviation Safety Agency.
