## Discrepancy

CAPTAIN REPORTED THAT DURING CRUISE STALL INDICATION FAILURE LIGHTS TURNED ON CONSTANTLY. DURING TEST IT WAS DETECTED THAT COMPUTERS REPORTED TX POS FLAPS AND SYSTEM DIFFERENCE FLAPS FAILURES.  AIRCRAFT WAS SENT TO THE HANGAR AND POSITION FLAPS TRANSMITTERS WERE REPLACED IAW MM.  DURING OVERNIGHT SERVICE WAS DETECTED DIFFERENCE IN TRANSMITTERS ANGLE ATTACK SIGNAL.  BOTH TRANSMITTER ANGLE ATTACKS WERE REPLACED AND STALL COMPUTERS WERE TESTED IAW MM 34-19-00 AND 34-19-01, ALL CORRECT.
