The European Aviation Safety Agency (EASA) issued a new  emergency airworthiness directive (2010-0242-E) for Rolls Royce RB211 Trent 900 series engines following a recent incident involving  such an engine on a Qantas A380.  This AD supersedes a previous emergency AD ( 2010-0236-E) that was issued on Novemer 10, 2010.

Since issuance of AD 2010-0236-E, the incident investigation has progressed and inspection data from in-service engines has been gathered and analysed.
The results of this analysis show the need to amend the inspection procedure, retaining the inspection of the air buffer cavity and focusing on the oil servicetubes within the HP/IP structure.

This AD partially retains the requirements of AD 2010-0236-E, which is superseded, and requires implementation of the amended procedure and accomplishment of the associated inspections.
