Narrative

I WAS WORKING MY NORMAL DAY SHIFT OF JUL/FRI/04. AT APPROX XA30 I WAS GIVEN A GATE CALL SLIP INFORMING ME ACFT WAS RETURNING. THE FLT CREW RPTED A NOSE GEAR UNSAFE INDICATION. THE MESSAGE ALSO SPECIFIED THE ACFT MAY BE OVERWT UPON LNDG. WE PROCEEDED TO GATE AND AWAITED THE ARR OF FLT. AFTER ARR; WE DEBRIEFED THE FLT CREW AND THEY EXPLAINED THE SIT. I CONTINUED TO ASK QUESTIONS TO BOTH CREW MEMBERS ABOUT THE DISCREPANCY TO AID IN TROUBLESHOOTING. DURING THIS TIME THE CAPT WAS FINALIZING HIS LOG ENTRY WHEN HE STATED HE LANDED OVERWT. I RESPONDED BY ASKING IF HE NOTICED ANYTHING DIFFERENT ABOUT THE LNDG; AT WHICH POINT HE INDICATED THE LNDG WAS UNEVENTFUL AND NORMAL. WE DECIDED THE BEST METHOD TO TROUBLESHOOT WOULD MEAN RETRACTING THE NOSE GEAR. THEREFORE; WE NEEDED A FORWARD BODY JACK. AT THIS TIME OUR SUPVR ARRIVED AT THE GATE. THE 3 OF US COORD TO GET THE JACK AND RELATED HARDWARE. IN PREPARATION TO RETRACT THE NOSE GEAR; I PINNED ALL GEAR. DURING THE PROCESS OF PINNING THE GEAR; I PERFORMED THE OVERWT LNDG INSPECTION. NO DEFECTS WERE FOUND. WE CYCLED THE NOSE GEAR MULTIPLE TIMES AND CONFIRMED THE FIX. WE REALIZED THE LOGBOOK WAS NOT ON LOCATION. THE LOGBOOK WOULD HAVE TO BE RETRIEVED FROM THE LINE MAINT LEAD OFFICE. I IMMEDIATELY SIGNED OFF THE R&R OF S-845 PER MAINT MANUAL. THOUGH IT WAS COMPLETED SEVERAL HRS EARLIER; I FAILED TO MAKE AN ENTRY STATING ACCOMPLISHMENT OF THE OVERWT LNDG INSPECTION.
