Narrative:

Flew aircraft from memphis to oakland (flight ab) and on takeoff went to raise the gear and the gear would not come up. Went through appropriate checklists determined to come back and land. When we put the flaps to 30 degrees, we had an aural warning horn which tells us the gear is not down and locked. Did a fly-by with the tower to see if gear was down. Went through the checklists a second time and came back for a successful landing. Pre-departure checked the logbook and discovered that the aircraft had a gear problem inbound to memphis. They performed corrective action before we left for oakland. After returning from our gear problem, maintenance noticed on the gear write-up, that the mechanic put the corrective action in the logbook but did not put his signature in the book. Because of this action, maintenance has put a voluntary disclosure to the FAA. Because of this incident, I am sending in the NASA report because of the issues involved. Our flight safety department is seeking corrective action.
