B737 Undifferentiated or Other Model
Flight Crew Air Transport Pilot (ATP)
Aircraft Equipment Problem Critical
Flight Crew Returned To Departure Airport; General Declared Emergency
After retracting the flaps during climb the First Officer was hand flying the aircraft and the electric stabilizer would not move the trim wheel. I pulled out the QRH and followed the Electric Stabilizer Trim Inop checklist. The trim wheel could not be moved electrically or manually. I called Maintenance to see if they had any ideas before returning to the field. We declared an emergency and asked to return. I called Operations and asked them to advise Dispatch of our situation.  We made an uneventful landing.
After takeoff we retracted gear and flaps. With flaps up before the autopilot was engaged; I was using the electric trim and it jammed and stopped moving. Takeoff trim was 5.5 units and failed at about 6.75 units. Electric trim seemed to work normal until flaps were retracted. The Captain followed the QRH Electric Stabilizer Trim Inop checklist. We declared an emergency. Returned to XXX and made a Flaps 15 overweight landing.
The pilots of a B737 identified a stabilizer trim failure following flap retraction during climb.  After following the Flight Manual procedure they were unable to correct the problem; so they declared an emergency and successfully returned to the departure airport.
