Not possible.
For one cubelet to be off like that indicates that the cube was misassembled. See here - any legal rotation or combination of rotations that involves flipped edge cubes will result in an even number of flipped edge cubes.

$\begingroup$ There is also puzzling.stackexchange.com/questions/521/… that asks essentially the same question, and the same principle applies to puzzling.stackexchange.com/questions/20/…, which should be considered an answer to both this question and the edge question I linked to. $\endgroup$ Jan 3, 2017 at 17:40

$\begingroup$ I was going along the lines that someone who sees this might want to try this on their own, and that some people might want to see the answer $\endgroup$ Jan 3, 2017 at 17:47
