After a series of crash landings (without major injuries), SAS has decided to remove their 27 Q400s from service permanently, an unprecedented move (as far as I know). The decision came after SAS suffered its 3rd crash landing involving Q400s in a month. The Q400 has been hailed as a quiet prop plane with great economics. It’s seen far more success overseas than in the US, where Americans are prop-adverse.
SAS has had to cancel more than 50 flights because of the decision.
