EASA issues an Emergency Airworthiness Directive (EAD)
22-Nov-2010 EASA has today issued an Emergency Airworthiness Directive (EAD) which supersedes that of the 11 November 2010 issued following the Rolls-Royce Trent 900 engine incident involving a Qantas Airbus A380.
The incident investigation continues. However inspection data from in-service engines has been gathered and analysed. The results show the need to amend the inspection procedures required by the EAD of 11 November 2010, retaining the inspection of the air buffer cavity and focusing on the oil service tubes within the high pressure and intermediary pressure structure.
This EASA directive still makes it mandatory for airlines operating Airbus A380 aircraft equipped with Trent 900 engines to perform repetitive inspections, a first one within a maximum of 10 flights, then at intervals not exceeding 20 flights. If any discrepancy is found following these inspections, further engine operation shall be prohibited.
The requirements of this EAD are considered interim action as the investigation led by the Australian Transport Safety Bureau is yet to deliver its final conclusions.
