Analysis
The crew reported that they noticed a decrease in climb rate while over rapid city, SD, en route from msp to sfo at flt level 310. The plt noted fuel burn was aprx 1400 lbs ahead of schedule. In-flt inspection revealed that the inboard trailing edge flaps had failed to retract properly after takeoff and remained in a 7 deg down position. The flt returnedto Minneapolis and landed at 1540 CDT (aprx 50 mins after the incident). A post flt inspection disclosed that the inboard flap control valve had failed. The flt crew said that this malfunction had occurred on a previous flt and had been reported. The flaps had ground checked ok both on this & the previous occasion. This reported failure was correctedby republic airlines maintenance by replacement of a flap control valve and inspection of the rigging in accordance withboeing maintenance manual 27-51-51, after this incident.
