## Discrepancy

ON LANDING APPROACH, O/B FLAPS DIDN'T EXTEND WITH FLAP HANDLE, I/B FLAPS OKAY.  SUBSEQUENT SYSTEM-A HYD HAD TOTAL LOSS.  CHECKLIST, M/GAR EXTENSION AND LANDED OKAY.  FOUND O/B TRAILING EDGE BYPASS VALVE BODY SEPARATED.  REMOVED AND REPLACED VALVE, LEAK CHECKS OKAY.  OPS CHECK FLAP SYSTEM, HYD AND ELECTRICAL, ALL CHECK OKAY PER MM 27-51-151.  DUE TO LOSS OF A-SYSTEM FLUID, PERFORMED MM 29-11-0 PAGE 102, ALL FILTERS ARE CLEAN AND REPLACED.  A/C OKAY FOR SERVICE.
