Probable cause
The captain’s use of his pitch trim switch, which had been placarded inoperative but not deactivated, resulting in the airplane pitching up when the captain was trying to trim down. The trim commands were reversed due to maintenance personnel’s incorrect installation of the pitch trim switch. Contributing to the incident was the operator’s delay in incorporating SB 170-27-0051 which would have prevented the switch from being installed inverted.
