48-13-02 BELL: Applies to Model 47 Series Equipped With Franklin 6V4-178-B3 and B32 Engines.
Compliance required at next preflight inspection.
Inspect fuel pump rocker pins to determine type. If pin has retaining rings which snap on each end, replace with new type pin having a head on one end and a staked washer on the other. Until new type pin is installed, daily inspection to determine the condition of the snap ring locks is required. A red paint dab for identification should be placed on all fuel pumps incorporating rocker pin change. Replacement pins are available through Aircooled Motors, Inc.
