Hamilton Accies delivered a blow to 10-man Dunfermline's hopes of a quick return to the Scottish Premier League.
Richard Offiong steered home a 47th-minute spot-kick after Phil McGuire had been sent off for fouling Stuart Taylor inside the box.
Accies had taken the lead when Taylor headed home from close range after only four minutes.
But former Celtic striker Mark Burchill seizing on a poor back-pass from Chris Swailes to bring his team level.
