Narrative:
I was the so on the flight from iah to atl. After departing runway 33 we were given a heading of 140 degrees. I performed my normal after takeoff checklist items. It was during the 'clean-up' after takeoff that we experienced the flap problem. Our inboard trailing edge flaps never left the 15 degree position. We discovered the abnormality later in the flight. We performed the malfunction procedures in the operating manual and landed uneventfully in atlanta.
