## Discrepancy

DURING DESCENT, AIRCRAFT INCURRED A NON-SYMMETRICAL FLAP CONDITION WITH THE LEFT FLAP SETTING AT 50 DEGREES AND THE RIGHT FLAP SETTING AT 30 DEGREES.  CAPTAIN DECLARED A YELLOW EMERGENCY SITUATION, ALERTED EMERGENCY EQUIPMENT, AND LANDED WITHOUT INCIDENT.  MAINTENANCE COMPLETED AND COMPLIED WITH EA 91-153375, SEC 1, STEP 4 LOG PAGE 7059108 IS THE ORIGINAL PILOT REPORT.  THE MAIN REPAIRS WERE MADE TO THE NR 3 FLAP HINGE, NR 2 FLAP HINGE ATTACH BOLTS, AND REPLACED THE RIGHT WING FLAP ASSEMBLY.
