A spokesman for Qantas said their were currently three builds or versions of the Trent 900, A, B and C. The incident on November 4 was in an A build engine, and all such builds have been removed from the Qantas fleet. The engines on the A380 now into its final hours of the flight from Singapore to Sydney are version B power plants. The spokesman also said that the three brand new A380s to be delivered to Qantas soon, two this month and one in the New Year, are currently powered with B and C build engines.
“Qantas doesn’t know if the (drilling issue) found on the engine on the aircraft involved on November 4 is a one off defect or a systemic problem,” he said. ” But we will find out. The inspections we are doing on all of the engines use a new 3D borescope different to the borescope used in the inspections specified in the EASA emergency airworthiness directive. There are only three of these 3D borescopes in the world and we have one of them.”
