Incident Overview
During the takeoff ground roll, all four right main body landing gear tires burst. The flight crew responded by executing a precautionary landing. The aircraft sustained substantial damage as pieces of the tires and wheel assemblies penetrated the fuselage structure.
Post-Accident Examination
A detailed examination after the accident revealed that the valve cores on three of the four inflation valves—including the two aft valves—were not torqued to the manufacturer's specifications. These valves were found to leak steadily.
Examination of the right aft main body landing gear tires (designated as number 11 and 12) showed evidence of having been operated in an over-deflected condition at some point prior to the event. This condition resulted in internal damage to those tires.
Accident Sequence
The investigation determined that the aft tires failed first as a direct result of the internal damage. Their failure initiated the accident sequence. The damage observed on the forward tires was consistent with them bursting due to impact from debris generated by the failure of the aft tires.
Damage Summary
The aircraft incurred substantial damage from tire and wheel debris penetrating the fuselage structure. No details on injuries or other consequences were provided in the source material.
