## Discrepancy

WITH FLAPS SET AT 1 FOR TAKEOFF, THE LE FLAPS TRANSIT AND LE FLAPS EXT LIGHTS WOULD ALTERNATE ON & OFF.  FLAP INDICATOR DID NOT MOVE FROM 1. ABORTED TAKEOFF.   THE AIRCRAFT WAS GROUNDED.  BITE CHECK FSEU, AND FOUND CODE 27-81222.  F4 PROX RETRACT. OPS CHECKED FLAPS. FAULT INTERMITTENT. OK FOR SERVICE.
