Chart Or Publication; Procedure; Aircraft
During initial descent received a MAIN PITCH TRIM INOP Master Warning. The Captain; who was flying; called for the QRH. Right afterwards the BACKUP PITCH TRIM INOP Master Warning was received. The Captain declared an emergency with ATC and asked for a delay vector while we ran the QRH. The QRH procedure fixed the BACKUP PITCH TRIM message but did not take away the MAIN PITCH TRIM message. We landed uneventfully in an emergency condition with use of the backup pitch trim. On the ground via phone; Maintenance had us do a few resets on the airplane and it was determined to be a computer problem not a flight control malfunction.
An EMB-145 alerted MASTER CAUTION for MAIN PITCH TRIM INOP followed shortly by a BACKUP PITCH TRIM INOP so an emergency was declared and; while on a delay vector; the crew was able to restore the Backup Pitch Trim before the emergency landing. Maintenance determined the Main Pitch Trim fault was a computer fault; not mechanical in origin.
