Tire Burst Test Methodology

scope:

This document describes a recommended test procedure to assess the burst characteristics of tires used on 14CFR Part 25 or similar transport airplanes.

Purpose

Each airframer is required to demonstrate compliance to 14 CFR Part 25.729(f) (FAA) and CS 25.734 and 25.1309 (EASA) with regard to the performance of the equipment and systems under a failure condition. The AMC 25.734 provides a set of models defining the threats originating from failures of tires and wheels.

Should an airframer wish to use a model other than those provided by the AMC, then they would have to gather sufficient evidence and present the data to the certifying authority in order to gain their acceptance of the alternative means of showing compliance.

There is no standard tire test methodology by which it can be determined how a tire will behave during an actual tire burst event. Standardization of the test and measurement method is beneficial since it allows the tire suppliers, airframers, and certifying authorities to consistently characterize the response of each candidate tire. This ARP presents such a standardized test.

It should be noted that this test method does not provide a characterization of every failure mode a tire can experience. It cannot be used to model a failure leading to a flailing tread, or a tread disbond failure, for instance. It is for this reason that it is important to involve the certifying authority at an early stage, in order to agree the extent to which the results of the test can be used in the showing of compliance.

This test has been proposed for the current tire technologies (bias and radial), however, should a new tire design be proposed, then the validity of this test method for fully capturing the failure modes of the new design would need to be re-evaluated.
