Narrative:

We were scheduled to fly a phenom 300; on an empty leg. After starting both engines the ventral rud fail - cas message illuminated and we shut the aircraft down and notified maintenance control. They immediately directed us to a procedure found in section 5 of the poh that is intended to reset the malfunctioning ventral rudder system by tripping and resetting a circuit breaker. Since the poh does not contain FAA-approved procedures I did not comply with his recommendation. I indicated that I would be amenable to working with maintenance control for troubleshooting purposes only and to provide information for maintenance personnel to use in diagnosing the problem. He argued that I am authorized to reset circuit breakers when directed to do so by maintenance control. Again; I reiterated that I would assist in troubleshooting only; and that I would not attempt to reset the malfunctioning system for the purposes of flying the aircraft without properly documenting the discrepancy.this is the second time I have been directed to complete one of the non-approved poh procedures by maintenance control in the last 3 weeks. There is absolutely no reason the maintenance controllers should be recommending we attempt to reset a malfunctioning system without first properly documenting the discrepancy. Properly training the maintenance controllers that pilots may only complete approved afm and aom procedures and that the pilot in command (PIC) has the ultimate authority for determining the airworthiness of the aircraft and will not participate in performing undocumented or unapproved maintenance procedures under any circumstances.

Title: Phenom 300 Captain reports receiving a VENTRAL RUD FAIL - CAS message after engine start and shuts down to contact Maintenance Control. Maintenance Control wants to do a circuit breaker reset which the Captain refuses to accomplish; believing it should be written up in the Logbook and corrected by a licensed Maintenance Technician.
