The sole survivor of a plane that went down at North Spirit Lake is suing the airline and the estate of the dead pilot, claiming negligence.
Brian Shead has filed the lawsuit in Winnipeg court.
Three passengers and the pilot were killed in the January, 2012 crash.
A Transportation Safety Board investigation concluded poor weather, ice on the wings and the pilot’s inexperience landing in icy conditions contributed to the deadly crash.
The lawsuit also alleges that Keystone Air Service was negligent because it failed to provide proper training to the pilot, didn't provide a plane that could handle the winter weather and applied pressure to its pilots to complete flights in adverse weather conditions.
None of the allegations have been proven in court.
The lawsuit is seeking unspecified damages for pain and suffering and loss of enjoyment of life.
Shead is also seeking undetermined out-of-pocket expenses, as well as compensation for loss of income,
belongings that were destroyed in the crash and damages for future costs of care.
