Aircraft Tire Retreading Practice - Bias and Radial
This SAE Aerospace Recommended Practice (ARP) sets forth criteria for the selection, inspection, retread and repair of worn civil aircraft tires, and the means to verify that the retreaded tire is suitable for continued service. This document is applicable to both bias ply and radial aircraft tires qualified subsequent to the adoption of this document.
Rationale: ARP4834 is the industry document supporting AC145-4A. This industry standard applies to both tubeless and tube type aircraft tires. For tube type tires, the diffusion performance capability of the assembly is controlled by the inner tube and not the tire. Since this standard defines the minimum performance capabilities of the tire, and not the inner tube, the diffusion performance threshold defined is only applicable to tubeless tires. It is, therefore, necessary to clarify this standard and to address diffusion for tube type tires under 7.1.9 and Section 10.
