## Discrepancy

DUE TO THE LT O/B FLAP TRANSMISSION BEING REPLACED AND THE FLAP POSITION TRANSMITTER BEING SWAPPED OVER NEED TO PERFORM A LAND VERIFY. WHILE PERFORMING THE LAND VERIFY IT WAS FAILING THE SURFACE TEST WITH AIL POS SEN-1 AND AIL POS SEN-2  FAULTS. DID TEST TWICE AND GOT SAME RESULTS. IN REF TO AMM 22-11-00. PERFORMED LAND VERIFY TEST REF M/M 22-11-00. OPS CHECK GOOD. AIRCRAFT RETAINS FULL CAT CAPABILITY. OK TO CONTINUE.
