## Discrepancy

(CAN) LEFT ENGINE RUDDER BOOST PRESSURE TRANSDUCER WAS REPLACED TO REPAIR A DEFECT WITH THE YAW DAMPER SYS.  AS A RESULT OF CHANGING THIS COMPONENT THE ACFT HAS SINCE EXPERIENCED 3 REJECTED TAKEOFFS, CADOR 2012C0963, 2012C0970 AND 2012C1569.  IN ADDITION TO THIS THE ACFT WOULD EXPERIENCE UNCOMMANDED RUDDER BOOST FAILURE. AFTER REMOVING THE RUDDER BOOST PRESSURE TRANSDUCER WE HAVE NOT HAD ANY ADDITIONAL FAILURES.
