Narrative:

No steering on pwrback. On pwrback from gate with a planned turn to my left, we had no steering because the steering bypass pin had not been removed prior to pwrback. During walkaround the pin was noted installed and tug/pushbar connected for planned pushback. During maintenance, to replace radome, maintenance personnel removed pushbar to access radome. Since we were now disconnected from tug, crew chief briefed a pwrback with left turn. Bypass pin was overlooked, hence no steering. No difficulties encountered during pwrback -- just came out of reverse and signaled for crew chief to remove pin.
