Narrative: We were on approach to landing Runway 27. I was pilot flying. The approach was normal; in the flare I brought the thrust levers to idle at the appropriate time. The left thrust lever stopped at idle and the right continued slightly. When I went to deploy reverse thrust; the left reverser deployed and the right thrust lever went back a little bit more. The Captain took control of the airplane when only the left reverser deployed. After we were pulled off the runway; I saw the right engine was in shutdown and the engine was spooling down. We stopped on the parallel taxiway and restarted the engine before taxiing back to the gate.


Second narrative: First Officer (FO) was the Pilot Flying and I was the PM giving instruction. Approaching Runway 27 everything looked really good; FO was doing a good job keeping airspeed and keeping the aircraft on glideslope. Touchdown was firm and on centerline and well within our standards. I was guarding the flight controls with my feet on the rudder pedals and hand on the yoke. My right hand was down low on the lower pedestal just in case I needed to take over and add power. After main wheels touchdown FO brought the nose wheel down nice and gentle. On the roll out; FO deployed thrust reversers with only the left deploying. I looked down at the switches and both reversers where armed. Rolling down the FO told me there was a split on the power levers and it was then that I realized the right engine was shut down. I took over the controls and taxied off the runway. I never saw the FO pull the [shut-off] trigger and I always saw his hand on top of the power levers. I really do not know how the right engine shut down. I really cannot say what the cause of this was; since Standard Operations Procedures (SOP) was followed. FO or I never pulled the trigger to shut down the engine. FO and I retraced our steps and could not come up with an explanation on what could have caused the right engine to shut down while on the rollout.

Second callback: Reporter stated the First Officer was in training and transitioning from Turboprops to their CRJ-700 aircraft. The aircraft and FO were performing just fine when the right engine suddenly shutdown. He has thought over and over again about the sequence of steps they had accomplished prior to the engine event and cannot find any reason for the shutdown except for an inadvertent contact with the shut-off trigger handle (switch) on the lower aft side of the engine throttle lever. All the more frustrating because the First Officer had performed very well and neither he; nor the FO could remember ever touching the shut-off trigger. Since the right engine restarted without any problems and no EICAS fault messages appeared; the possible movement of the right engine shut-off trigger seems to be the only plausible explanation.

Synopsis: A First Officer and Check Pilot reported a sudden; unexplained shutdown of the right engine on a CRJ-700 aircraft during the landing rollout on a training flight. The Check Pilot noted he never saw the FO pull the right engine shut-off trigger and only observed the First Officer's hand on top of the power levers.
