Narrative:

Gear up landing made by pilot during test flight of an aerostar 601P which had ferry tanks installed and was now operating on a special 337 flight permit which permitted test flts prior to leaving for an around-the-world flight. I was a crew member because under the 337, no passenger are permitted. Eventually I would have acted as PIC on 50 percent of test and trip flying. Various distrs of testing equipment and very faint gear warning horn (sounding like middle marker) contributed to this incident. Also, pilot rarely ever does pattern flying -- gear up then gear down, etc. Supplemental information from acn 303102: testing of equipment for upcoming long range flight a probable distraction plus pattern flying done only rarely in many yrs.
