## Discrepancy

FLT 236, STI-JFK. ON 08/28/2018 AT JFK, WHILE TROUBLESHOOTING A HYDRAULIC LEAK COMING FROM THE LT WING TRAILING EDGE AFT OF THE PYLON, THE GREEN MAIN HYDRAULIC POWER PIPE INSTALLATION BULKHEAD CONNECTOR (REF. IPC 29-11-05-3D ITEM) WAS FOUND SEPARATED FROM THE LOWER WING SKIN PANEL 3 MOUNTING PLATE. THE CONNECTOR IS ATTACHED TO A MOUNTING PLATE WITH TWO BOLTS, WITH THE MOUNTING PLATE ATTACHED TO THE LOWER WING SKIN PANEL 3 SECTION THAT EXTENDS AFT OF THE REAR SPAR IN THE AREA OF THE FALSE REAR SPAR BETWEEN RIBS 7 AND 8. THE AREA OF THE CONNECTOR ATTACHMENT ON THE MOUNTING PLATE WAS FOUND BROKEN AWAY, ENLARGING THE ORIGINAL HOLE IN THE PLATE THAT SURROUNDED THE HYDRAULIC PIPE PASS-THRU, INDICATING THAT THE BOLTS ATTACHING THE CONNECTOR TO THE DOUBLER MUST HAVE TORN AWAY THE MATERIAL OF THE DOUBLER THAT THEY WERE ATTACHED TO. PREVIOUSLY WE HAD A SIMILAR ISSUE PER REF/4/, CONTACT AND PROVIDED REF/1/ TEMPORARILY, HOWEVER OPTED TO MX FERRY THE AIRCRAFT FOR THE PERMANENT REPAIR AT MRO. SINCE THIS AC IS DUE AT HEAVY CHECK IN 150FC, WE WILL ACCOMPLISH REPAIR PER REF/3/ WITH WEEKLY RE-INSPECTION OF THE DOUBLER. PERMANENT REPAIR WILL BE ACCOMPLISHED WITHIN 150FC. MX WILL GENERATE A MDDR PER GMM TO TRACK THE WEEKLY RE-INSPECTION. EC A18-680-01 IS THE TEMPORARY DOUBLER REPAIR PER REF/1/. EC A18-680-02 IS TO ACCOMPLISH THE PERMANENT REPAIR PER SRM 57-21-11-300-005 WITHIN 150FC; THIS PERMANENT REPAIR IS AS PER REF /2/ SRM.
