Narrative:

During climb out at 4000 ft MSL, a master warning signaled indicating that both the main and backup pitch trim system were inoperative. At the time, I was flying and the captain was running the QRH with the emergency checklists. After the captain had communicated with dispatch and maintenance, he made the decision that we would return to the field (sdf). We made an uneventful landing (flaps 22 degrees and landing speeds adjusted per the QRH). After taxiing to the gate, maintenance reset the system and completed all of the requirements. The flight departed again normally, but delayed. Upon further investigation by the captain, we discovered the emergency checklist in the QRH was part of an old revision and was incomplete. The new revision, however, was available in our company issued poh's. After checking several other company aircraft, the captain noticed they too had old QRH revisions.
