(b) If a crack in any nut is found, prior to further flight replace the nut with a specially marked Part No. 81790-1414 nut per Figure 2 of the above referenced Service Bulletin.
(c) This AD does not apply if each affected nut has been replaced by a specially marked Part No. 81790-1414 nut per Figure 2 of the above referenced Service Bulletin.
(d) Return cracked nuts to Beech Aircraft Corporation, Commercial Service, Department 52, P.O. Box 85, Wichita, Kansas 67201-0085.
(e) Airplanes may be flown in accordance with FAR 21.197 to a location where thisAD can be accomplished.
(f) An equivalent method of compliance with this AD, if used, must be approved by the Manager, Wichita Aircraft Certification Office, FAA, 1801 Airport Road, Room 100, Wichita, Kansas 67209; telephone (316) 946-4400.
All persons affected by this directive may obtain copies of the documents referred to herein upon request to Beech Aircraft Corporation, Commercial Service, Department 52, Wichita, Kansas 67201-0085, or these documents may be examined at the FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.
