ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 72-19-02 PITTS AVIATION ENTERPRISES, INC: Amdt. 39-1518. Applies to the Pitts Model S-2A Series Airplanes, S/N 2001 through 2025. Compliance required within the next 10 hours time in service after the effective date of this AD, unless already accomplished. To prevent structural damage because of excessive in-flight vibration of the aileron interconnect tubes, accomplish the following: (a) Remove streamline aileron interconnect tubes, P/N 2-5216-1. NOTE: Make certain the length between the AN3 bolt centers for the upper and lower aileron attachments of the interconnect tube are not changed during removal. (b) Install round aileron interconnect tubes, P/N 2-5216-11. When installing the replacement tubes, make certain to adjust the length of the lower threaded end to the same overall length between AN3 bolt centers as the tubes originally installed on your airplane. Make certain that the correct number of AN960-10 (1/16 or 1/32 inch thick) washers are installed so that the bearing inner races are clamped-up snugly without bending the fork ends of the tubes. Pitts Service Bulletin No. 5, including Supplement No. 1, pertains to this same subject. This amendment becomes effective September 15, 1972. FOOTER:
