So an O-ring got put into an invisible location -- worse, quality control did not catch it.
It looks like there was a rush put on to turn out 54 MLG assemblies, perhaps a bunch of overtime -- and one came out mis-assembled.
Much like SAS has rushed to blame the problems on the aircraft.
"This O-Ring did not come from the actuator and its source is unknown."
If the O-ring is not from the actuator then how did it get in there?
3 accidents in 1.5 months with the same carrier. There is a better chance statistically that this is a SAS maintenance issue rather then a systemic problem with the aircraft!
I'm curious as to how many of the other Q400's in service around the world were found to have the corrosion problems that SAS had with the earlier incidents?
