## Discrepancy

(CAN) NR 2 STALL WARNING/STICK PUSHER CAUTION LIGHTS ON, BUT THEN WENT OUT.  ONCE AIRBORNE, CREW NOTICED THE NR 2 SW/SP CAUTION LIGHT AGAIN.   CREW RETURNED.  SW/SP COMPUTER REPLACED, BUT SAME PROBLEM OCCURRED.  FURTHER INVESTIGATION FOUND THE NR 2 AOA VANE PINS 8 AND 9 WERE SHORTED INTERNALLY TO PIN 12.  THUS, SW/SP COMPUTER DID NOT PICK UP FAULTY.  ALPHA VANE REPLACED.
