## Discrepancy

AUTOFEATHER SYSTEM DOES NOT ARM.  ABORTED TAKEOFF AND RETURNED TO THE GATE.  SYSTEM ARMED AND TESTED NORMALLY ON THE GROUND DURING TEST MODE.  REPLACED POWER LEVER SWITCHES 6121-S12 AND 6121-S13.  ALSO, REPLACED NR 1 AND NR 2 TORQUE SIGNAL CONDITIONERS (TSEU).  OPERATIONAL CHECKS GOOD.
