AN AIRBUS 320 WAS DISPATCHED IN NON COMPLIANCE WITH #1 REVERSER LOCKED OUT FOR MAINT.

Narrative

ON THE NIGHT OF AUG/XA/99; I WAS ASSIGNED TO PERFORM THE #9A CHK ON THE #1 ENG OF AN A320. I FOLLOWED THE JOB CARD PROCS WHICH REQUIRE THE DEACTIVATION OF THE HYD THRUST REVERSER CTL UNIT BY INSTALLING A SAFETY PIN IN THE CTL UNIT. WHILE I CONTINUED WITH THE ENG SVC I FOUND A COUPLE OF DISCREPANCIES THAT WOULD NEED TO BE ADDRESSED. ONCE THE SVC WAS COMPLETED; I PROCEEDED ON TO A LEAKING HYD LINE; AND THEN TO HELP 2 ASSOCIATES WITH SOME CASE COOLING MOUNT BEARINGS THEY WERE HAVING TROUBLE REPLACING. AS TIME PRESSED ON; IT WAS NEAR TO PUSHOUT AND RUN THE ENGS FOR LEAK CHKS. IT WAS AT THIS POINT I BECAME RUSHED AND MISSED REACTIVATING THE THRUST REVERSER HYD CTL UNIT. I DID NOT REALIZE MY MISTAKE UNTIL I WAS ON MY WAY HOME AND THE ACFT WAS ALREADY AIRBORNE. AT ONCE I CALLED THE STATION MAINT CTLR AND EXPLAINED THE PROB. I WAS TOLD HE WOULD CONTACT THE LINE MAINT CTLR AND ALLOW THEM TO HANDLE NOTIFYING THE AIR CREW. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE LAST STEP ON THE JOB CARD WAS RESTORE THE ACFT TO NORMAL. THE RPTR SAID THE JOB CARD DID DIRECT THE TECHNICIAN TO INSTALL THE LOCKOUT PIN BUT DID NOT DIRECT THE TECHNICIAN TO REMOVE THE PIN. THE RPTR STATED THAT NO OPS CHK OF THE REVERSER WAS REQUIRED ON THE JOB CARD.
