The Canadian Transportation Safety Board (CTSB) determined a failure of Crew Resource Management was largely responsible for the crash of First Air Flight 6560, a Boeing 737-200, in Resolute, Nunavut, on August 20, 2011. A malfunctioning compass gave the crew an incorrect heading, although the instrument landing system and Global Positioning System indicated they were off course. The first officer made several attempts to indicate the problem to the captain but a failure to follow airline procedures and a lack of a standardized communication protocol to indicate a problem led to the captain dismissing the first officer's warnings.
