Q400 Gear Incidents Prompt Inspection Recommendation

A second incident involving the collapse of a right main landing gear shortly after touchdown on a Bombardier Q400 operated by SAS has prompted an OEM recommendation.

The first incident occurred at Aalborg, Denmark, on September 9. The second incident occurred on September 12 at Vilnius, Lithuania. There were no reported injuries.
As a precautionary measure, Bombardier and Goodrich, the landing gear manufacturer, recommend in an all-operator message (AOM) that operators of Q400s with more than 10,000 landing-gear cycles (a cycle is one takeoff and landing) be grounded until the landing gear has been inspected.

Bombardier has delivered more than 160 Q400s to airlines around the world. About 60 of them have logged more than 10,000 landing-gear cycles.
Bombardier is providing assistance to the investigating authorities and won’t comment on the cause of the incidents until the investigations are concluded.
