Pineridge is another guy who thinks he knows something before the final reports. No need to investigate.

Can´t we just wait till the reports come out!

compensation negotiated between the two parties for Bombardier`s mistake of selling SAS an aircraft that SAS mechanics couldn`t maintain properly.
Of course! If that wasn't the case, they would have gone with Embraer.
It's not a question of pride, but both sides won!

Issue settled.....life goes on!

"Can´t we just wait till the reports come out!"

We might have to wait for a long time; I have just read that SAS have found some fatigue cracks in the wing bolts of one of their DHC-8`s. According to the news report (in Norwegian, sorry) they are checking the whole fleet, on the advice or direction of the Canadian and U.S. (?) authorities.

Thank-you, Per, I was certainly amused but I am not sure that others will be enlightened.

Flaps2billion and Pineridge,
I´m sure you guys can tell me who´s at fault regarding the wing bolts, without waiting for the final report...

The March 2007 nose gear incident in Japan has been investigated, and turns out some Bombardier mechanics forgot to install a bolt while repairing the ANA Q400 in question. Happens sometimes, I guess.

Something is rotten in the state of Denmark.

The Danish newspaper, Berlingske Tidene, has reported that it has received information about the incident on the 27th October 2007 at Copenhagen Airport where a DHC-8 400 aircraft belonging to SAS had a main gear collapse on landing.
The subsequent investigation by the Danish authorities (SLV) placed responsibility for the gear failure at the door of the manufacturer, Bombardier, who have not accepted the blame. The investigation found a rubber O-ring, foreign to the system, in the gear.
The head of the SLV office in Copenhagen, Peter Udsen, apparently wrote several times to his superiors that in his opinion the cause of the incident was that the SAS mechanics had used an unapproved procedure when changing two valves in the gear system.
Apparently, SLV`s technical director, Per Veingberg, replied to Udsen that they were not interested in his personal opinion in the matter and thereafter kept the correspondence with Udsen secret. Udsen has since left the SLV`s employ.
The contribution of the SAS mechanics to the incident was not included in the accident report because, according to Veingberg, SAS does everything by the book.
The accident inspector responsible, Kurt Færch Madsen, denies that the mechanics at SAS can have made a mistake but thinks that the rules regarding changing the valves were perhaps unclear.
SAS`s communications director says that they have followed all the rules exactly.
The final report is expected this Summer, ass-covering operations have already begun.

3 identical gear failures, one type, one airline only. There are bigger operators of the Q400 without any gear failures. Conclusion...........?

Terrific!
That leaves us with about 3 months to speculate, guess, rant, slag, bitch, moan and bs about what "really" happened, all based on what yet another journo claims happened behind closed doors somewhere, including a "he said/he said" and hopefully a conspiracy or two.



Good Grief.

While the media can stuff up a story, they can also be right on something very significant. For example, the media that eventually brought down the Queenland Government through the (IIRC) Wood Royal Commission on police corruption.

It´s not 3 identical gear failures. The final report for the first one is released. See http://www.hcl.dk/graphics/Synkron-L...t%20LN-RDK.pdf

Read it and see factors leading to the accident and safety recommendations. Conclusion.....?

Still waitning for the final report on the third.

Flybe is the world's biggest Q400 operator. No gear failures. No Canadian failures, so local conditions are not a factor. What inference should you make? Maybe production line changes for a particular series? Maybe local maintenance practices?

Rainboe, I still recommend you to read the report.
It´s not production line changes, local conditions or local maintenance practices behind the FIRST incident. It was a problem with the design of the acuator and rod end.

SAS was the launch customer, and struggled for a long time with the first deliveries. The two first accidents were due to a design fault admitted by Bombardier.

This third accident was different. The so called new and withheld information was already included in the preliminary accident report from November 2007.
http://www.hcl.dk/graphics/Synkron-L...K_03112007.pdf

Prior to the accident the SAS mechanics used a component from a spare part pre-assembled for the nose gear, on the main gear. This may have contributed to the failure in the hydraulic system, which was initially caused by a loose O-ring traveling in the system.

The Danish authorities mentioned (SLV) is the Danish CAA. They are not responsible for the accident investigations in Denmark, and therefore it makes little sense to question what information they excluded or will exclude from their report.

The question now is whether the procedure used by the SAS was an allowed procedure or not. The representative from the Danish Accident Investigation Board stated that there is no evidence of sloppiness within SAS, but that the guidelines may have been unclear. If he was referring to SAS or Bombardier guidelines is not clear.
