(b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

(c) An alternate method of compliance or adjustment of the compliance time which provides an equivalent level of safety may be approved by the Manager, Airplane Certification Office, Federal Aviation Administration, Department of Transportation, Fort Worth, Texas 76193-0150.

Note: The request should be forwarded through an FAA Maintenance Inspector, who may add comments and then send it to the Manager, Fort Worth Airplane Certification Office.
