Narrative:
I found unlatched fasteners under the right engine during my exterior inspection. Because of maintenance cards and forms in the logbook, the captain said it looked as if maintenance was still working the aircraft. I informed him of the latches. Approximately 10 mins prior to departure a maintenance man arrived and began to sign the logbook. I asked what he had done and had he left the latches open for his coffee break. The captain asked if the latches were secure to which the maintenance man nodded affirmatively. As gear locked up on takeoff, tower said we had a flapping right cowling. Returned to runway 9R mia. Overweight landing and cowling departed aircraft at touchdown. Turned off runway and shut down right engine for inspection. Returned to gate.
