## Discrepancy

(CAN) DURING "C" CHECK, FUNCTIONAL CHECK ON TASK CARD 3230/15 (OPS CHECK OF LANDING GEAR DOOR SEQUENCE CONTROL CIRCUIT) DOES NOT WORK. AFTER INVESTIGATION, RELAY (3261-K9 )SOCKET FOUND BROKEN AND PINS OLDER SOCKET UNGLUED. WIRE WERE FOUND HANGNING LOOSE WITH A HI RISK OF CONTACT WITH STRUCTURE. POSSIBILITY OF "WOW" CIRCUIT FAILURE AND THE MOST IMPORTANT, IMPOSSIBILITY OF GEARS EXTENTION IN ALTERNATED RELEASE IN CASE OF EMERGENCY EXTENSION. DURING THE SAME CHECK, RELAY SOCKET 7611-K3 (SAME RELAY SOCKET) WAS ALSO FOUND CRACK. THAT MEANT TWO SOCKETS FOUND CRACKED ON THE SAME ACFT.
