50-41-01 TAYLORCRAFT: Applies to All Model B Series Aircraft, Serial Numbers 1001 and Up.
Compliance required not later than November 15, 1950.
Reports have been received of interference between the elevator horn bolt and the fin cover plate apparently caused by improper field installation of the cover plate through bolt. Cases are known where the bolt has worn through the cover plate and such interference may result in jamming of the elevator control system. An inspection of the parts should be made and if evidence of interference is noted, suitable means of preventing the cover plates from interfering with the elevator horn bolt should be incorporated; a spacer bushing at least 1/4 x 0.028 x 1 1/4 inches installed around the cover plate through bolt is considered satisfactory.
(Taylorcraft, Inc. Service Bulletin 65 covers this same subject.)
