## Discrepancy

NR 2 ENGINE FIREX DISCHARGE LINE 4 EA OPENINGS ALL CAPPED WITH FLEX HOSE AND PLUG TEST EQUIPMENT.  FIREX LINE IS DIRECTLY ABOVE ENGINE FAN CASE.  TEST EQUIPMENT WAS FOUND DURING OPEN UP.  [SUP 05-16-07]  THE INSTALLED CAPS, FLEX HOSE AND TEST EQUIPMENT ARE USED DURING A PRESSURIZED LEAK TEST OF THE EXTINGUISHER DISCHARGE SYSTEM. THIS TEST WAS LAST PERFORMED ON THE AFFECTED AIRCRAFT DURING A REGULARLY SCHEDULED C-CHECK ON 8/29/2005. AT THAT TIME, THE MECHANICS WHO PERFORMED THE TEST FAILED TO PUT THE DISCHARGE SYSTEM BACK INTO A FLIGHT WORTHY CONDITION AND THE ERROR WAS NOT DISCOVERED TILL THE MOST RECENT C-CHECK WAS PERFORMED ON 1/29/2007.
