## Discrepancy

ON DESCENT INTO ELKO, RIGHT NACELLE WOULD NOT EXTEND PAST 15 DEGREES WITH CONTROL FAULTS.  AFTER LANDING, ALL FLAPS RETRACTED.  THEREAFTER, RIGHT NACELLE FLAP WOULD NOT WORK, CAUSING FLAP ASYMMETRY.  REMOVED AND REPLACED NACELLE FLAP ACTUATOR.  REMOVED AND REPLACED FLAP CONTROL BOX.  OPS & LEAK CHECKS GOOD.
