SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   77-17-04 MOONEY: Amendment 39-3006 as amended by Amendment 39-3258. Applies to Models M20, M20A, M20B, M20C, M20D, M20E, M20F, and M20G airplanes, certificated in all categories with over 1000 hours' time in service.
Compliance required within the next 30 days after the effective date of this AD, unless already accomplished within the last 250 hours' time in service and thereafter at intervals not to exceed 500 hours' time in service from the last inspection.
To prevent failure of the control wheel shaft due to cracking with associated crack growth, accomplish the following:
(a) Remove the RH and LH control wheels and inspect the aft two inches of the control wheel shaft for cracks (particularly at the attachment holes for the wheel). Use visual and dye penetrant inspection methods.
(b) Replace or modify any cracked shafts with new original configuration shafts or with the strengthened configurations described in Mooney Service Bulletin M20-205B dated May 3, 1978, before further flight.
(c) Reinstall the RH and LH control wheels.
(d) Replacement of parts required by paragraph (b) with new original configuration parts will permit the establishment of new initial inspection times for the inspections of paragraph (a). The new initial inspection time is 1,000 hours' time in service after parts replacement. Replacement or modification of parts required by paragraph (b) with the strengthened configurations described in Mooney Service Bulletin M20-205B will remove the requirement for the 500-hour repetitive inspections.
(e) Aircraft may be flown in accordance with FAR 21.197 to a base where this AD can be accomplished.
(f) The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to the Service Manager, Mooney Aircraft Corporation, P.O. Box 72, Kerrville, Texas 78028. These documents may also be examined at the Office of the Regional Counsel, Southwest Region, FAA, 4400 Blue Mound Road, Fort Worth, Texas, and at FAA Headquarters, 800 Independence Avenue, S.W., Washington D.C. A historical file on this AD, which includes the incorporated material in full, is maintained by the FAA at its headquarters in Washington, D.C., and at the Southwest Regional Office in Fort Worth, Texas.
(g) Equivalent methods of complying with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Southwest Region.
Amendment 39-3006 became effective August 18, 1977.
This amendment 39-3258 becomes effective July 7, 1978.
