## Discrepancy

(CAN) DURING LANDING ROLL, ONE ENGINE DID NOT RESPOND CORRECTLY TO SELECTION OF REVERSE THRUST. AS A RESULT, THE AIRCRAFT DEPARTED THE RUNWAY.  VARIOUS ENGINE ACCESSORIES HAVE BEEN REMOVED FOR EVALUATION.   MFG WILL MONITOR THE INVESTIGATION AND WILL SUPPLEMENT THIS REPORT TO PROVIDE ROOT CAUSE, ONCE ESTABLISHED.
