Narrative:

Air carrier X was cleared to land at san juan puerto rico's runway 10. At approximately 200 ft we heard the tower give atx Y a 'go around.' the copilot looked to his right to see the belly of a twin engine aztec turning right. We landed without incident. The captain spoke with the tower operator and supervisor and pilot of the aztec. It appears the tower controller cleared the aztec for a 'olympic' arrival to runway 10 with clearance to land. This is a local non published procedure and calls for a tight right turn to final. Heavy aircraft are usually cleared for an approach to runway 10 and land runway 8. If requested, heavy aircraft may be cleared to land on runway 10. The controller cleared both aircraft for landing runway 10. At the last min the tower controller directed the aztec to go around.
