Narrative:

During flight iah/mia; we noticed no in-flight abnormalities until the flaps were extended to 1 degree at about 210 KTS. To maintain heading; the control wheel was displaced about 2 units right. The winds at mia were quite gusty which resulted in choppy air. After the flaps were beyond 5 degrees; we noticed no problems. The rest of the approach and landing were normal and we thought about it no further. While parked at gate between flts; ramp worker noticed a problem with the left outboard flap. The aft flap panel outboard section appeared to be off track and did not retract properly. Maintenance was called and eventually pulled the aircraft OTS. The ramp worker was very observant and helpful.
