From the Wikipedia article
In September 2007, two separate accidents due to similar landing gear failures occurred within three days of each other on Bombardier Dash 8 Q400 aircraft operated by Scandinavian Airlines System (SAS). A third accident, again with an SAS aircraft, occurred on 27 October 2007, leading to the withdrawal of the type from the airline's fleet.
Investigation and cause
Investigation
When the handle for lowering the landing gear was activated, the indicator showed two green and one red light. The red light indicated that the right main gear was not locked in position. The landing was aborted. Attempts at lowering the gear manually were also unsuccessful. An investigation into the cause of the failure to deploy revealed that the right main gear hydraulic actuator eyebolt had broken away from the actuator. A further analysis of the actuator showed corrosion of the threads on both the inside threads of the piston rod and the outside threads of the rod end, leading to reduced mechanical strength of the actuator and eventual failure.
On 19 September 2007, the prosecutor of Stockholm commenced a preliminary investigation regarding suspicion of endangering another person.
