Narrative:
On takeoff from cvg on runway 27 we were climbing through 1500 ft when the #2 engine started to roll back 5-15%. It then surged back to just past normal. It then settled to normal then repeated the roll back and return to normal. I asked for vectors to land at cvg and was turned for vectors to runway 36L. We landed without incident. No emergency was declared, but the emergency equipment was rolled as a precaution. The engine remained running throughout the approach and landing. There was a pilot seated in the first row who told us he heard and felt the power surge.
