What happened
At 2245:29 CST, the flight crew of a DC-10 reported reaching the final approach fix for an Instrument Landing System (ILS) runway 9R approach. The fix was located 4.7 miles from the runway threshold. The aircraft had been cleared to land. Shortly thereafter, a snow removal team, which was working on runway 32L, requested permission for four vehicles to cross the active runway 9R. The tower controller granted clearance for the vehicles to cross.
At 2247:28, the lead man of the vehicle group reported that they were clear of the runway. However, as the fourth vehicle was approximately halfway across, its manual transmission jumped out of gear, and the driver struggled to reengage it. At 2248:00, the lead man notified the tower of the mechanical issue. By this time, the DC-10 was already on final approach.
After the aircraft touched down and the spoilers were deployed, prior to the nosewheel being lowered, the flight crew spotted the stalled vehicle at the edge of the runway. The captain took immediate evasive action, steering the aircraft around the obstacle. The landing continued without further incident.
