## Discrepancy

AFTER TAKEOFF FROM ORD, EN ROUTE TO PHL, CREW WAS UNABLE TO RETRACT THE FLAPS.  FLAPS LOCKED OUT AT 5 UNITS.  FLIGHT RETURNED TO FIELD AT ORD AND LANDED WITHOUT FURTHER INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE REMOVED AND REPLACED THE RIGHT FLAP TRANSMITTER AND THE FLAP POSITION INDICATOR, P/N 2061-14-1.  ALSO, REPAIRED A LOOSE BONDING JUMPER FOR THE RIGHT FLAP TRANSMITTER.  OPS CHECK GOOD.  (M)
