Lessons Learned - Main Landing Gear (MLG) Tire Rupture During Postlanding Operations
Year: 1992
Abstract: Description of Driving Event:
MLG tire heat generated from max. Braking due to a crosswind landing, heavy orbiter, or long landing, could cause a transfer of heat to continue to the MLG tires after wheel stop, resulting in a delayed tire blowout. An explosive tire rupture caused by increasing tire pressure, cuts, excessive loading, or skidding could injure personnel and/or damage the orbiter/chassis hydraulic system/ ground support equipment. Three thermal relief plugs in each MLG tire prevent tire overpressurization, the orbiter anti-skid/brake control system prevents locked brakes, and the orbiter hydraulic system displacement limiter limits hydraulic fluid loss.
