Airbus's negligence contributed to a crash landing at Halifax Stanfield International Airport two years ago, Air Canada claims in a lawsuit against the French aircraft manufacturer.
In a statement of claim filed in Nova Scotia Supreme Court, Air Canada said Airbus SAS failed to identify shortcomings of the Airbus 320.
The document said it did not advise that in certain conditions, the plane's flight path angle could be affected by external forces.
It also claims Airbus failed to incorporate a warning system to alert pilots to a deviation from the planned flight path angle.
"(Airbus) failed to provide adequate and/or accurate information as to how pilots should correct a deviation in the flight path in circumstances where manual intervention was required," the March 28 claim said.
None of the allegations have been proven in court.
The statement of claim does not specify an amount for damages, but says: "(Air Canada) pleads that (Airbus) was negligent and that its negligence caused or contributed to the damages claimed in the within action."
"Damages claimed herein include the damage sustained by the aircraft and other expenses related to the subject incident," it said.
Airbus did not immediately return a request for comment Thursday and has not filed a statement of defence. Air Canada declined to comment, as the matter is now before the courts.
Flight 624 hit the ground about 200 metres short of runway 05 shortly after midnight on March 29, 2015, as it approached in gusty winds and heavy snowfall.
The twin-engine plane bounced into the air and crashed near the runway threshold before careening along the tarmac for another 570 metres.
