Narrative:
Flap failure after departure. Contacted dispatch and maintenance control. Was requested by dispatch and maintenance control to burn fuel prior to landing. Elected to hold for 35 minutes to get landing weight below 44000 pounds; maximum weight outlined in aom vol 1 for unfactored landing distance. Returned to ZZZ for an uneventful overweight landing. Suggestions: better guidance in aom vol 1 for flap failure right after takeoff in regards to overweight lndgs.callback conversation with reporter revealed the following information: the reporter stated that both channels of the flap power units failed with the flaps not fully retracted. This was the reporter's first experience of total trailing edge flap failure on this airplane. Reporter stated that better guidance is needed in the operating manual for overweight lndgs. The corrective action taken by maintenance is unknown.

Narrative: FLAP FAILURE AFTER DEPARTURE. CONTACTED DISPATCH AND MAINT CTL. WAS REQUESTED BY DISPATCH AND MAINT CTL TO BURN FUEL PRIOR TO LNDG. ELECTED TO HOLD FOR 35 MINUTES TO GET LNDG WT BELOW 44000 LBS; MAX WT OUTLINED IN AOM VOL 1 FOR UNFACTORED LNDG DISTANCE. RETURNED TO ZZZ FOR AN UNEVENTFUL OVERWT LNDG. SUGGESTIONS: BETTER GUIDANCE IN AOM VOL 1 FOR FLAP FAILURE RIGHT AFTER TAKEOFF IN REGARDS TO OVERWT LNDGS.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT BOTH CHANNELS OF THE FLAP POWER UNITS FAILED WITH THE FLAPS NOT FULLY RETRACTED. THIS WAS THE RPTR'S FIRST EXPERIENCE OF TOTAL TRAILING EDGE FLAP FAILURE ON THIS AIRPLANE. RPTR STATED THAT BETTER GUIDANCE IS NEEDED IN THE OPERATING MANUAL FOR OVERWT LNDGS.
