From the report:
During the replacement of the MSV, the rogue O-Ring found blocking the orifice in the restrictor valve of the accident aircraft could, hidden in a union, have unknowingly been transferred from one side of the MSV to the other side by maintenance personnel
From SAS 5 days earlier:
"Confidence in the Q400 has diminished considerably and our customers are becoming increasingly doubtful about flying in this type of aircraft. Accordingly, with the Board of Directors' approval, I have decided to immediately remove Dash 8 Q400 aircraft from service," says Mats Jansson, President and Chief Executive Officer of SAS.
"The Dash 8 Q400 has given rise to repeated quality-related problems and we can now conclude that the aircraft does not match our passengers' requirements concerning punctuality and regularity. SAS's flight operations have always enjoyed an excellent reputation and there is a risk that use of the Dash 8 Q400 could eventually damage the SAS brand," says John Dueholm, Deputy CEO of SAS.
Maybe too early?
Same John Dueholm is quoted in a Danish Newspaper for saying SAS customers has lost confidence in the Q400, and so SAS will stop flying them. SAS will consider replacing the Q400s with ......... (get this).......
.........Q400s
Since never version of the Q400 does not have the same problems as the first version SAS recieved as a launch customer. !
2 Questions for John dueholm then (and the rest of you)
Is a newer version of the Q400 going to restore customer confidence ?? Afterall in non-professional eye it still looks like the one that landed gear up a couple of times.
Is the newer Q400 more reliable because it is not as old... YET ??
Earlier in this thread somebody was ranting SAS and their own perception of how safe they are. Although I disagree with that post, I can see where that public opinion comes from when I hear an SAS manager suggest something like this
