A B737-500 WAS DISPATCHED IN NON COMPLIANCE WITH A REVERSER LINE NOT CONNECTED TO THE STANDBY HYDRAULIC POWER MODULE.

Narrative

REPLACED STANDBY HYDRAULIC MODULE IN MLG WHEEL WELL PER MAINT MANUAL ON AUG/FRI/2004. ON SEPT/FRI/2004; HYDRAULIC LINE FOR REVERSE WAS FOUND NOT HOOKED UP TO MODULE. MAINT MANUAL DOES NOT REFERENCE A PLUG TO BE REMOVED OR AN ADAPTER TO BE INSTALLED ON THE STANDBY HYDRAULIC MODULE FOR REVERSER LINE TO BE CONNECTED. MAINT MANUAL DOES NOT REFERENCE AN OPERATIONAL TEST OF THE REVERSERS UPON COMPLETION OF STANDBY HYDRAULIC MODULE REPLACEMENT. HAD EITHER ITEM BEEN STATED IN THE MAINT MANUAL; I BELIEVE THE ERROR WOULD NOT HAVE TAKEN PLACE. SUPPLEMENTAL INFO FROM ACN 630803: ACCOMPLISHED LEAK CHECK OF MODULE AFTER UNIT REPLACED. ACCOMPLISHED OPERATIONAL TEST OF STANDBY MODULE. TEST PASSED REFERENCE MAINT MANUAL. REFERENCE ILLUSTRATED PARTS CATALOG. THIS JOB WAS ACCOMPLISHED AFTER A TURNOVER FROM PREVIOUS CREW; WHICH HAD ALREADY CHANGED MODULE; BUT NEW MODULE WAS BAD (CRACKED) SAME PLACE ORIGINAL WAS. WE CONTINUED ON WITH NEW PART. CALLBACK CONVERSATION WITH RPTR ACN 630943 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE REVERSER LINE THAT SHOULD HAVE BEEN ATTACHED TO THE STANDBY HYDRAULIC POWER UNIT WAS DISCONNECTED BY ANOTHER SHIFT DURING THE MODULE REMOVAL AND PUSHED BACK BEHIND THE 'B' PUMPS OUT OF SIGHT. THE RPTR SAID THE STANDBY HYDRAULIC PWR UNIT WAS INSTALLED PER THE MAINT MANUAL AND TESTED OK FOR SERVICE. THE RPTR STATED THE MANUAL DOES NOT CALL OUT THE INSTALLATION OF THE ADAPTER FOR THE REVERSER LINE. THE RPTR SAID THE REVERSER WAS NOT ON THE OPERATIONAL TEST IN THE MAINT MANUAL. THE RPTR STATED THE ILLUSTRATED PARTS CATALOG PICTORIAL VIEW OF THE STANDBY HYDRAULIC MODULE SHOWS THE REVERSER PORT HAVING A PLUG INSTALLED NOT AN ADAPTER FITTING FOR A LINE CONNECTION. THE RPTR SAID THE REVERSER LINE ADAPTER FITTINGS AND 'O' RING SEALS WERE TO BE INCLUDED WITH THE UNIT RECEIVED FROM STORES BUT WERE NOT WITH THE MODULE.
