47-16-02 DOUGLAS: (Was Mandatory Note 17 of AD-762-7.) Applies to C-54 and DC-4 Aircraft. \n\n\tTo be accomplished not later than June 1, 1947. \n\n\tIn case of leakage of the oil dilution solenoid, fuel may flow down the flexible conduit between the solenoid and the firewall junction box and into the junction box, thus creating a fire hazard. To correct this condition, remove the existing flexible conduit and wire between the solenoid and junction box and install new 18-gage wire. Support wire with AN 755-4-4-8 clamps spaced approximately 10-inches apart. \n\n\tThis change is similar to the removal of the flexible conduit for the primer solenoid as covered in item 25 of Douglas Service Bulletin 266 in accordance with Note 47-02-04. \n\t(Part 2A, item 4 of Douglas Service Bulletin DC-4, No. 66, dated June 18, 1947, covers this same subject.)
