Incident Overview
While taxiing for departure, the airplane's No. 12 tire on the right body landing gear (RBLG) contacted foreign object debris (FOD). This contact resulted in a cut tire and loss of tire pressure. An electronic message reflecting the loss of pressure in the No. 12 tire was displayed on the engine indicating and crew alerting system (EICAS) in the cockpit; however, no further action was taken by the flight crew.
Takeoff Roll Events
During the takeoff roll, the two aft tires on the RBLG—No. 11 (inboard) and No. 12 (outboard)—burst. The associated wheels fractured as a result of the tire bursts. The burst tires and fractured wheels caused minor damage to the airplane.
Return and Landing
Following the tire bursts, the airplane returned to the airport and landed uneventfully. No anomalies were noted during the return or landing.
Post-Incident Examination
Examination of the airplane's systems and wheel assemblies revealed no additional anomalies beyond the damaged tires and wheels. The investigation did not identify any other contributing factors or system malfunctions.
