The airworthiness directive
52-25-02 ERCOUPE: Applies to Models 415-C and -CD Aircraft Having a 5.00x4 Nose Wheel and Using Federal Skis.
To be accomplished not later than December 1, 1952.
To eliminate instances of the nose ski coming off when operating on Federal Aircraft Works Model A-1500 skis, a supplementary safety device should be installed. A simple and suitable device is a rectangular plate (approximately 1/8-inch thick and 1/2-inch longer than axle diameter) installed to end of axle stub so that ends of plate will prevent retaining nut from backing off if lock washer fails. This plate, which will also provide for visual inspection of retaining nut, to be held in place by a safetied through bolt. This modification can easily be made and installed in the field. Drawing (No. ES-B-203) describing such an installation is available from Federal Aircraft Works, Minneapolis, Minn.
(Federal Service Bulletin No. 100 also covers this subject.)
