## Discrepancy

R/H ATTENUATOR BELCRANK (CASTING) FAILED AT CENTER PIVOT FRAME RENDERING THE ATTENUATOR DOOR INOP AND AND GIVING AN UNSAFE ANNUNCIATOR LIGHT WHICH ALLOWED HYDRAULIC SYSTEM TO CONTINUE TO RUN WHERE NORMALLY AN DUMP/UNLOADING  VALVE WOULD ENERGIZE AND ALLOW FLUID TO BYPASS. THANKFULLY AIR CREW ABORTED TAKEOFF AND RETURNED FOR MAINTENANCE. UPON INSPECTION OF COMPONENTS, I OBSERVED THE HYDRAULIC TANK AND SURROUNDING AREA EXTREMLY HOT DUE TO SYSTEM NOT BEING UNLOADED.
