This SAE Aerospace Recommended Practice (ARP) defines a procedure for demonstrating service overload capability for new, main and nose landing gear, radial or bias tires fitted on multiple wheel landing gear of Part 25 certified aircraft.
Many OEMs impose an overload condition on the tire that exceeds the current 1.5 factor required in TSO-C62e. The overload condition described herein is recommended in support of FAR 25.1309 (a) and (b) considering continued safe flight and landing following the loss of load carrying capability of one tire on a multiple tire landing gear. In addition to maximizing safety, economic damage is mitigated by ensuring the remaining tire(s) on a landing gear perform their intended function following the loss of load carrying capability of one tire on a multiple tire landing gear. A service overload test should be a recommended practice to achieve a minimum level of safety for aircraft certified under 14 CFR Part 25.
