Narrative:

During a scheduled line check, I noted a discrepancy that the yaw trim would not move to the right. I replaced the whole panel. This was on nov/xa/98. On nov/af/98 a discrepancy was made that the standby pitch trim switch was moving incorrectly to position selected. The standby pitch switch was replaced and the aircraft left with a slight delay. My only contributing factor is that it took 6 days and another scheduled (and completed) line check before the discrepancy was found by a pilot. Parts need to be inspected better or more carefully before being tagged, to prevent parts being bad from stock.

Title: A SAAB 340A HAD A TRIM CTL PANEL REPLACED FOR A DISCREPANCY FOUND BY A MECH ON A SCHEDULED CHK AND 6 DAYS LATER THE PANEL WAS REPLACED AGAIN DUE TO A PITCH TRIM SWITCH INSTALLED INCORRECTLY.

Narrative: DURING A SCHEDULED LINE CHK, I NOTED A DISCREPANCY THAT THE YAW TRIM WOULD NOT MOVE TO THE R. I REPLACED THE WHOLE PANEL. THIS WAS ON NOV/XA/98. ON NOV/AF/98 A DISCREPANCY WAS MADE THAT THE STANDBY PITCH TRIM SWITCH WAS MOVING INCORRECTLY TO POS SELECTED. THE STANDBY PITCH SWITCH WAS REPLACED AND THE ACFT LEFT WITH A SLIGHT DELAY. MY ONLY CONTRIBUTING FACTOR IS THAT IT TOOK 6 DAYS AND ANOTHER SCHEDULED (AND COMPLETED) LINE CHK BEFORE THE DISCREPANCY WAS FOUND BY A PLT. PARTS NEED TO BE INSPECTED BETTER OR MORE CAREFULLY BEFORE BEING TAGGED, TO PREVENT PARTS BEING BAD FROM STOCK.
