Narrative:
When on final approach to runway 17C, I was cleared to land. When approximately by the OM I had a pitch trim 1 fail on EICAS. However, the pitch trim on the first officer's side was not working either I was on final and did not having too much time to run another checklist. I had good control of the airplane. I continued to the runway making a normal landing. At the gate, we called maintenance operations center and fixed the problem by resetting the circuit breaker. The airplane continued flying normally. The back-up trim was working normally. Also, I have seen pitch trim problems before, but the indication is only for a few seconds then disappears without failures.callback conversation with reporter revealed the following information: the reporter stated the embraer 145 has repetitive pitch trim failures and EICAS warnings that disappear after a few seconds. The reporter said, in this incident, the #1 system was inoperative and indicated as such with the EICAS warning. The reporter said the circuit breaker was found tripped and reset by maintenance.

Narrative: WHEN ON FINAL APCH TO RWY 17C, I WAS CLRED TO LAND. WHEN APPROX BY THE OM I HAD A PITCH TRIM 1 FAIL ON EICAS. HOWEVER, THE PITCH TRIM ON THE FO'S SIDE WAS NOT WORKING EITHER I WAS ON FINAL AND DID NOT HAVING TOO MUCH TIME TO RUN ANOTHER CHKLIST. I HAD GOOD CTL OF THE AIRPLANE.
