| 11:39 PM | Cross Runway 4 at taxiway D | Tower to Truck 1 |
| 11:40 PM | Truck 1 stop, Truck 1 stop | Tower (multiple attempts) |
The National Transportation Safety Board has deployed a full investigation team to examine all aspects of the collision. This includes aircraft maintenance records, crew qualifications, airport ground vehicle operations, and air traffic control procedures. The investigation will determine whether communication failures, equipment malfunctions, or procedural errors contributed to this tragic mass casualty event.
