## Discrepancy

WHILE RETURNING TO BASE, CREW NOTICED AN INCREASING STRONG ELECTRICAL ODOR AS THE ACFT TURNED FINAL.  CONTINUED TO THE LANDING AREA AND PUT THE ACFT OUT OF SERVICE.  CREW SAW NO SMOKE BUT ONLY THE ODOR.  MAINTENANCE FOUND YAW COMPUTER TO BE FAULTY AND REPLACED IT. NO CIRCUIT BREAKERS WERE DISPLACED AND LOAD METERS READ NORMAL THROUGHOUT THE EVENT. THERE WERE NO OTHER ABNORMALITIES OR DAMAGES.  (K)
