Required Actions
Review the airplane logbook to determine whether GCU installation kit, P/N 128-3001-1 P or 128-3001-3 P, is installed. If no kit is found or cannot be conclusively determined, replace Shinko GCUs with new Lucas Aerospace/Goodrich GCUs (installation kit P/N 128-3001-1 P or 128-3001-3 P). If the kit is found installed, inspect to determine the P/N of both GCUs and inspect current sense transformers as specified in Table 2. Replace transformers as applicable.
