## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain aviation tires installed on various transport category airplanes. This AD requires a one-time inspection of the nosewheel tires to determine if they are within a designated serial number range, and replacement if necessary. This AD results from reports of tread separations and tread-area bulges on the nosewheel tires. We are issuing this AD to prevent tread separation from a nosewheel tire during takeoff or landing, which could result in compromised nosewheel steering or ingestion of separated tread by an engine, and consequent reduced controllability of the airplane on the runway or in the air.
