Norwegian CAA stated to NRK (TV) that it "...will be a long time..." before the Q400 is allowed into the air again.
I remember the early days of Q400 i SAS service. It was a bit of a turkey then too, with spurious fire indications with associated diversions. And snags on the ground. At Ängelhom we ran out of ramp space once in 02 due to broken Q400s.
(Yes, yes..... tiny ramp
)
