Aviation authority reports cold weather hazard for Goodyear inner tubes
Several reports of inner tube failure during cold weather operations have prompted the Federal Aviation Administration in the US to issue a Special Airworthiness Information Bulletin warning of possible failures involving butyl rubber inner tubes manufactured by Goodyear Aviation Tires. The bulletin has been issued as a recommendation and the FAA states that at present the inner tube failure in question does not constitute a safety issue that would warrant airworthiness directive action.
