Narrative:
Oil check accomplished on #2 engine. 9 pints added. Noted leak check required due to high oil consumption embraer technical notes. Aircraft had departed station. Maintenance control notified and aided in determining inspection was required. Course of follow-up action being discussed. While reviewing work card; noted 9 pints oil added to #2 engine requires notifying maintenance control. Contacted maintenance control; reviewed embraer technical notes. Determined oil consumption rate above embraer technical notes limit which requires fault isolation manual task for external leak check. Aircraft had departed for flight; could not comply with leak check.

Narrative: OIL CHK ACCOMPLISHED ON #2 ENG. 9 PINTS ADDED. NOTED LEAK CHK REQUIRED DUE TO HIGH OIL CONSUMPTION EMBRAER TECHNICAL NOTES. ACFT HAD DEPARTED STATION. MAINT CTL NOTIFIED AND AIDED IN DETERMINING INSPECTION WAS REQUIRED. COURSE OF FOLLOW-UP ACTION BEING DISCUSSED. WHILE REVIEWING WORK CARD; NOTED 9 PINTS OIL ADDED TO #2 ENG REQUIRES NOTIFYING MAINT CTL. CONTACTED MAINT CTL; REVIEWED EMBRAER TECHNICAL NOTES. DETERMINED OIL CONSUMPTION RATE ABOVE EMBRAER TECHNICAL NOTES LIMIT WHICH REQUIRES FAULT ISOLATION MANUAL TASK FOR EXTERNAL LEAK CHK. ACFT HAD DEPARTED FOR FLT; COULD NOT COMPLY WITH LEAK CHK.
