Narrative:

Upon takeoff roll aircraft lost #4 engine cowl. During the day we had cowls open on all the engines. We closed them and they all appeared to be latched and secure. Supplemental information from acn 199900. I arrived after work was completed, performed walk around, signed air worthiness release and dispatched aircraft.
