Narrative:
The initial climb instructions were to depart runway 27 on runway heading and climb to and maintain 3000 feet. After rotation and gear/flap retraction; it became apparent that primary pitch trim had failed causing an excessive nose up pitch trim to be maintained. The crew recognizing they were experiencing a non-annunciated failure of the primary pitch trim used SOP's and CRM to maintain control of the aircraft and begin the level off at our initial clearance altitude. Due to the inoperative pitch trim and the associated excessive control forces; the aircraft climbed to an altitude of approximately 3150 feet while the crew was in the process of reverting to stand by pitch trim. The crew quickly recognized the issue and once the aircraft was appropriately trimmed with the standby system returned to 3000 feet. The appropriate procedures were followed and maintenance personnel were contacted to discuss the issue. The best corrective actions of following appropriate checklists and returning to home base were selected and executed. Once at a safe altitude and stable configuration the crew attempted to revert back to primary pitch trim at which point the system was deemed operable again. The flight was completed with normal pitch trim and autopilot used with close monitoring of the flight control and trim configuration. Maintenance was debriefed upon arrival.
