The Metro II aircraft was on a routine scheduled flight (PAG207) from Winnipeg (YWG) to Gods Lake Narrows (YGO) to Gods River (ZGI) with a return flight to Winnipeg. The right main landing gear touched down approximately 345 feet before reaching the threshold of runway 27. The wheels of the right landing gear travelled about 20 feet and struck a snow ridge which had been created as snow removal equipment turned in the under run area. The ridge was about 2 feet high and consisted of frozen snow. The right landing gear drag links failed and the right gear moved rearward pivoting at the trunnion. The left gear wheels touched down about 326 feet ahead of the runway threshold. The aircraft slid off the right side of the runway and sustained substantial damage. The right main landing gear punctured the fuel tank in the right wing when the gear collapsed.
