Narrative:

We were in cruise flight. I was the first officer flying from the left seat. We were at 11000 ft on our way to prn, al. We got a right engine low oil pressure light and had to shut the engine down. We returned to birmingham. We never declared an emergency. We only advised ATC of our problem. It appeared the captain did not completely lock the oil cap and we had a leak. Also the oil door was not secure and blew off somewhere. The captain admitted he probably left the cap and door unsecured.
