## Discrepancy

(CAN) WHILE DOING THE CLEAN STALL TEST, THE SHAKER FIRED 2 KNOTS ABOVE THE CALCULATED VALUE. THEN, WHILE SLOWING THRU 2 KNOTS BELOW THE SHAKER, THE AIRCRAFT STARTED BUFFETING AND DEVELOPED A PRONOUNCED ROLLTO THE LEFT. THE PUSHER ACTIVATED 3 KNOTS ABOVE THE CALCULATED VALUE, BUT THE ANGLES AT THE PUSHER SHOWED 14.5 & 14.6. AIRCRAFT RETURNED WITHOUT FURTHER OCCURRENCES. UPON ARRIVAL, THE LT AND RT AOA VANES NUL ADJUST WERE FOUND OUT OF TOLERANCES AT 0.7/0.6 INSTEAD OF 0.8 IAW FTP601R2731U. VANES WERE ADJUSTED IAW FTP601R2731U AND AIRCRAFT RETURNED TO FLIGHT WITHOUT FURTHER OCCURRENCES.
