Description / Abstract:
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.
Purpose
The purpose of this ARP is to provide a recommended procedure
for the testing of aircraft tires for multiple tire landing gears
under the foreseeable condition that one of the tires on the
landing gear loses its load carrying capability during normal
operations of the aircraft, resulting in a condition where the
remaining tire(s) on the landing gear must carry the landing gear
loads for the remainder of the flight. It is the performance of the
highest loaded remaining tire which is the focus of this ARP.
Compliance with this report is not considered approval for
installation on any category aircraft. The OEM for the platform for
which the equipment is intended should be consulted for concurrence
with the approaches proposed herein as an acceptable qualification
demonstration for aircraft tires under overload conditions.
Application
This ARP is applicable to aircraft tires subject to TSO-C62 and
for installation on 14 CFR Part 25 aircraft and should be
considered for any aircraft configuration changes that cause any
re-assessment of the design data used for the approval of the tires
(e.g., to achieve TSO-C62 approval) or for the installation
approval of the tires on the aircraft.
The procedures recommended herein are considered to represent an
acceptable performance standard in support of FAR 25.1309 (a) and
(b). OEMs may have internal standards that differ from those
prescribed herein based on company specific lessons learned.
