Narrative:

We had a left pneumatic system fault on takeoff out of slc en route to ZZZ. Continued on to ZZZ where we left the plane for our layover. We were taking the same plane out the next morning. The captain called in the morning to make sure the aircraft had been fixed and was ready to go. When we arrived at the aircraft we were given a message from maintenance to run aircraft engines before departure. Under our logbook entry that we made the contract mechanic had signed 'cleared fault, re-racked controller, needs engine run. He had signed underneath with his a/P number and signature. We ran engines before dispatch and everything was good. Once airborne we realized we probably needed to enter our engine run into the logbook. We consulted our fom (flight operations manual) and found the contract mechanic had not properly signed off the logbook, by not signing in the 'mechanic signature' block or 'corrective action block.' upon arriving in dfw we called out maintenance out to make sure our logbook entry was correct. They then informed us maintenance should have observed the engine run before signing logbook.
