This document covers the basis of, and test procedure for, an overspeed landing test on aircraft tires with rated speeds of 190 mph (306 km/h) and above. The conditions requiring an overspeed test, alternatives, test requirements and pass/fail criteria are addressed.
Rationale: Overspeed landing is an emergency condition that can occur with certain aircraft requiring the aircraft to land at a speed higher than the design norm. For this condition, a standardized test method is needed to demonstrate a tire's capability to withstand this condition. This revision clarifies the relationship and the acceptance critierion for a tire passing the overspeed landing test, demonstrating a tire’s capability to withstand the landing of an aircraft experiencing this condition.
