Runway Overrun

On April 12, 2007, a Pinnacle Airlines Bombardier CRJ-200 overran the runway at Traverse City, Michigan, during a scheduled flight from Minneapolis, Minnesota. The flight faced delays due to weather, with crew fatigue and limits on duty time contributing to decision-making issues. The airplane landed on a snowy runway, experiencing insufficient friction and braking performance. Despite deploying thrust reversers, the aircraft exited the runway resulting in separation of the nose gear. Fortunately, all passengers exited safely. This report highlights safety concerns regarding crew fatigue and runway operations in winter conditions.

  1. Runway Overrun Bombardier CRJ-200 Pinnacle Airlines Traverse City, Michigan April 12, 2007

  2. History of Flight • Scheduled flight from Minneapolis, Minnesota • Delayed due to weather • Crew duty time near limits • Crew complained of being tired • First officer new to airplane

  3. History of Flight • Winds acceptable, flight dispatched late • Crew received field condition report • Thin wet snow over patchy thin ice • Friction 40 MU • Landing distance assessment • Required, not performed • Would have shown insufficient length for conditions

  4. History of Flight • Aware of contaminant • Careful with thrust reversers • Airport operations • Accumulating snow • Braking “nil” – blocked transmission • “Probably nil” • About ½ inch snow accumulation

  5. History of Flight • Continued approach • Touchdown 2,400 feet • Deployed thrust reversers twice • Airplane yawed and exited runway • Nosegear separated • Passengers exited safely

  6. Safety Issues • Flight crew decision-making • Fatigue • Check airman duty limits • Runway criteria – winter weather • Airport operations communications

  7. Parties to the Investigation • Federal Aviation Administration • Pinnacle Airlines • Northwest Airlines • Northwest Regional Airport Commission • Air Line Pilots Association • GE Aviation • Transportation Safety Board – Canada • Bombardier • Transport Canada
