It was excessive vibrations from a blown tire that led to the hard landing of an Air Canada flight making an emergency landing in Edmonton in 2014. On November 6th, the Jazz Aviation Dash 8 bound for Grande Prairie had its tire blow as it took off from Calgary.
When the pilot tried to land in Edmonton, the landing gear collapsed, which caused a propeller blade to slice through the cabin wall. Three people were sent to hospital with minor injuries.
A Transportation Safety Board investigation has found that the shaking from the blown tire falsely triggered a sensor that released the landing gear. The report says that this could happen again to similar aircraft if components and completed airframes don’t undergo dynamic vibration testing.
