Narrative:

I deferred, at a non airline maintenance station, the #2 engine oil quantity on a 737-222 aircraft per the MEL. However, the MEL allows deferral for 3 days, by using category 'B' for deferral. I, inadvertently, listed the item as category 'C' which caused the oil quantity system not to be fixed for 5 days. (2 days past limit) at time of deferral I was extremely busy.

Title: IMPROPER MEL DEFERRAL.

Narrative: I DEFERRED, AT A NON AIRLINE MAINT STATION, THE #2 ENG OIL QUANTITY ON A 737-222 ACFT PER THE MEL. HOWEVER, THE MEL ALLOWS DEFERRAL FOR 3 DAYS, BY USING CATEGORY 'B' FOR DEFERRAL. I, INADVERTENTLY, LISTED THE ITEM AS CATEGORY 'C' WHICH CAUSED THE OIL QUANTITY SYS NOT TO BE FIXED FOR 5 DAYS. (2 DAYS PAST LIMIT) AT TIME OF DEFERRAL I WAS EXTREMELY BUSY.
