## Discrepancy

FUEL CELL OPENING 624AT HAS A LOOSE CLIP TO BOTTOM SKIN AT MID POSITION. RIVETS REMOVED, HOLE REAMED FOR HILOCK INSTALLATION, HLT418-6-4 INSTALLED, BUT THERE IS NO SUPPORTING DATA TO ALLOW HILOCK USE IN THIS AREA. MAINTENANCE REMOVED CLEAT AND REINSTALLED SAME CLEAT USING 1/64IN OVERSIZE NR 6 HILOCKS DUE TO LOOSENESS OF CLEAT. REFERENCE Q400 SRM 51-40-10. USED HLT 70-6 COLLARS ON THE HILOCKS. HORIZON EA 6-57-483 AUTHORIZES THE USE OF FIRST HILOCK IN PLACE OF RIVETS.
