The hidden accusition against Lufthansa and Lufthansa Technik regarding the C check in September is no new information. It was posted several times before in the old thread to this case. As early as post nr. 240 there was a statement of a Lufthansa Technik spokesman quoted whith the content that Lufthansa Technik has no responsibility for the engines. Quantas has obviously only contracted Lufthansa Technik for the "Body" C-check only.
Under the present contract of "power by the hour" I believe even Quantas is not responsible for the status and service readiness of the engines, itīs sole RR business. There might be excemptions from this strict ruling - subject to contract details - e.g. minor service activities at the stations that are involved in A 380 operation, but thats all.
I think this whole case is much too serious to start apppointing of blame without solid facts at hand.
