Narrative:

On routine flight from fxe to fll entered left base, completed pre-landing checklist. Flaps full down, landing gear was not selected down due to distraction. Retarded throttles and heard gear horn. Sounded like asymmetrical thrust warning. No action taken. Landed runway 13 with no landing gear. Callback conversation with reporter revealed the following information: reporter operates a part 129 advisor/technical operation for foreign acrs maintenance programs and handles aircraft manuals and MEL tech literature production. He has a high amount of hours and carries but a private pilot license. He normally has another rated pilot with him but did not in this instance. The other occupant was a corporate mechanic. The aircraft was a piper 601 aerostar which he uses as a freighter. Reporter cited several distrs that allowed the event to occur. Traffic was heavy and he was about #5 in line. He had been asked to land and hold short of runway 9R. He had business meetings on his mind and he was late. He said schedule pressure was felt and he was upset. The mechanic was taking pictures of the approaching runway with a still camera and had little flying experience. The asymmetrical warning referenced is a dual pitot system mounted on the engine nacelles that issues a warning of yaw sensed from varied pressures (from an engine failure) and produces an indicator arrow in the cockpit, pointing to the failed engine. The sound is the same as the gear warning horn. Those 2 warning sounds are the only ones in the aircraft. Reporter says he is going to change the 'engine' warning to a bell type.
