Incident Overview
During the takeoff roll just prior to rotation, all four main landing gear tires failed. The parking brake had been set on the icy runway to perform an engine runup. The captain stated that he had released the brakes at the beginning of the roll, and the copilot reported hearing the brakes release. However, neither pilot checked whether the red parking brake light was illuminated.
Inspection Findings
A post-incident inspection revealed that both the captain's and copilot's parking brake actuation rigging were out of adjustment. The exact nature of the misadjustment was not specified in the source, but the condition likely prevented the brakes from fully releasing despite the pilots' actions.
Observations
The sequence of events began with the crew setting the parking brake on an icy runway. After completing the engine runup, the crew initiated the takeoff roll. The pilots believed the parking brake was released based on their actions and auditory cues. The lack of visual verification via the parking brake light was noted as a contributing oversight.
The failure of all four main landing gear tires occurred during the acceleration phase, just before the aircraft would have rotated for liftoff. The source does not state whether the aircraft successfully aborted the takeoff or continued, nor does it provide details on any injuries, damage to other components, or the aircraft type.
