What was found
DURING REPLACEMENT OF THE RELIEF TUBE DRAIN HEATER, FOUND THE WIRES FROM THE ORIGINAL HEATER SLEEVE TO SPLICES AT027 AND AT028 WERE UNDER-CRIMPED AND EASILY PULLED THE WIRE FROM THE PIN SOCKET. ALSO, THE INSULATION WAS OVER-STRIPPED, EXPOSING TOO MUCH WIRE BEHIND THE PIN. IT WAS NOTED THAT THE WIRING ON THE ACFT SIDE OF SPLICE IS 20 GA., AND THE HEATER SLEEVE WIRES ARE 24 GA. ADDITIONAL, THE SAME SPLICES WERE CHECKED ON ANOTHER ACFT AND FOUND THE SAME THING, PINS UNDERCRIMPED AND WIRES OVER-STRIPPED.
