Narrative:
Shortly after departure, the flight crew received STAB TRIM and MACH TRIM caution messages on the Electronic Information Control Advisory System (EICAS), and the horizontal stabilizer control system would not reset. The crew declared an emergency, and the flight returned to the departure airport and landed without incident. Company maintenance personnel removed and replaced the horizontal stabilizer trim control unit (HSTCU), and motor control unit (MCU) from the airplane, and the airplane was returned to service. The HSTCU and MCU were tested and examined per manufacturer specifications, and no anomalies were noted that would have contributed to the caution messages. The failure of the horizontal stabilizer control system was not determined.

Probable Cause: The failure of the horizontal stabilizer control system for undetermined reasons.
