Also Flybe has had problems with landing gear. I work behind a radar screen and have witnessed when Flybe Dash 8's fly a sector landing gear down. No accidents yet.
Flybe have had no recent issues with the gear not extending. Some of the fleet were flown to major engineering bases with the gear locked down (pins in) for precautionary checks in accordance with Bombardiers recommendations.
Hopefully there won't be too many jobs lost at SAS with this announcement
