ACFT ARRIVED AT GATE FROM THE HANGAR AT XA04. IT WAS SCHEDULED TO DEPART AT XA30. MAINT WAS CALLED AT XA35 BY MAINT CTL AND ADVISED THE ACFT HAD A WRITE-UP FOR PUSHER SYS FAIL CAUTION LIGHT THAT ILLUMINATED AFTER ENG START. THE TECHNICIAN WORKING THE PROB PULLED UP AND PRINTED FROM ENGINEERING PUBS. ON THE TECHNICIAN'S WAY OUT OF THE OFFICE THE LEAD INFORMED HIM THAT 'I THINK IT'S PRE MODIFICATION BUT I NEED TO CHK.' THE LEAD INITIATED DIALOG WITH TECHNICAL SVCS AT THAT TIME AS THERE IS CURRENTLY NO MODIFICATION DATA AVAILABLE ON ENGINEERING PUBS. APPROX 1/2 HR ELAPSED UNTIL TECHNICAL SVCS COULD GIVE THE LEAD AN ANSWER TO WHETHER OR NOT THE ACFT WAS PRE- OR POST-MODIFICATION AND THE WORD CAME BACK THAT THE ACFT WAS POST-MODIFICATION. THE LEAD THEN CALLED THE TECHNICIAN AND RELAYED THAT THE ACFT WAS POST-MODIFICATION; THAT SVC LETTER WAS NOT APPLICABLE AND THE FLT INFO MANUAL NEEDED TO BE USED FOR RETURN TO SVC. AT THAT TIME THE TECHNICIAN INFORMED THE LEAD THAT THE ACFT WAS SIGNED OFF AND GONE. SVC LETTER WAS THE TECHNICAL DATA REFED ON THE LOG PAGE FOR RELEASING THE ACFT. MAINT CTL WAS NOTIFIED OF THE DISCREPANCY AND HAD MAINT INITIATE A WRITE-UP TO CLR WITH THE FLT INFO MANUAL TASK; WHICH THEY DID. ALL CHKED GOOD AND THE ACFT WAS RETURNED TO SVC.
