Plane maker Bombardier ordered the grounding of at least 40 percent of its Q-400 turboprop planes after a Scandinavian Airlines aircraft skidded off a runway with 52 people aboard Wednesday, the second such incident in three days.

No one was injured when the landing gear failed, forcing the emergency touchdown in Lithuania. However, the accident followed the crash landing late last week of a Scandinavian Airlines flight that suffered a similar failure in Denmark, injuring five people.

That SAS turboprop carrying 73 people caught fire Sunday after its right landing gear collapsed during an emergency landing at Aalborg's airport.

The grounding Wednesday forced the cancellation of at least 200 flights worldwide. Both SAS and Horizon Air, a regional U.S. carrier operated by Alaska Air Group Inc., each canceled more than 100 flights to inspect their turboprop aircraft.
