This incident could have major ramifications on ETOPS. Unless there was a procedural or maintenance problem with this specific aircraft then surely A330 ETOPS will also have to be suspended pending investigation.
Also, given that all ETOPS operations are justified by the huge odds against both engines failing in flight, will this damage ETOPS credibility?
Given that virtually every airline operating on the Atlantic now relies heavily (or entirely) on big twins can the industry afford a large scale review of ETOPS?
