WASHINGTON (Sept. 4, 2012)—The Federal Aviation Administration has issued an airworthiness directive on Goodyear aircraft tires manufactured for use on certain airplane models made by the Brazilian firm Bombardier Inc.
Essentially, the action amounts to a recall of the Goodyear tires. The FAA decided to issue the directive after Brazil’s aviation agency found tread separations and tread-area bulges on main landing gear tires caused by low adhesion in the tread shoulder area, the FAA said in its Aug. 29 final rule.
The tires in question are new tires, size H29x9.0-15, used on the Bombardier CRJ-100, CRJ-200 and Challenger 850. Retread tires of this model and size are not included in the airworthiness directive, the FAA said.
The agency estimates that about 3,400 Goodyear tires are covered by the directive. It also estimates that the total cost of correcting the problem will be $7.5 million or $2,255 per tire.
Goodyear told the FAA that some of those costs may be covered on a one-to-one basis under the service bulletin Goodyear issued about the tires in April 2012.
Probably no more than 100 of the tires covered by the directive are still in service, a Goodyear spokesman said.
