NOTE:____ A vibration survey can be done at the operator's discretion when the fan blades are replaced or when the same fan blade set is installed again. The survey results will show if it is necessary to do the Fan Trim Balance or if the installation is correct (AMM 72-31-00/501).
NOTE:____ If the vibration survey results show a fan blade imbalance greater than 400 gram cm (157.5 gram inches), do the Vibration Survey again after you do the static correction of the blades. Refer to figure 407.
