ENGINE ABNORMAL VIBRATION

If engine vibration is due to ice accumulation, reduce the associated
thrust lever to idle and then advance to 70% N1 minimum. Wait
30 seconds and operate the thrust lever as required.
If engine vibration is not due to ice accumulation, reduce N1 to achieve
green range vibration, then advance to desired N1.
If vibration does not return to normal range, reduce the associated
thrust lever in order to keep vibration within normal range.
If unable to keep vibration within limits and engine parameters
become abnormal or exceed operating limits, consider an engine
shutdown.
