(14) If the engine is to be put in storage, do the drying procedure for the bearing compartment (AMM 71-00-03/201) (optional).
NOTE: Water can condense in the engine bearing compartments both
____ during and after the flight where the engine is ferried. This occurs because of temperature and pressure changes and can cause corrosion on parts of the bearings. If the engine turns freely, the engine will be lubricated sufficiently to decrease the possible damage. You must do the drying procedure for the bearing compartment in areas of high humidity.
