What is this about?
Due to a deviation in the manufacturing process, excessive application of LOCTITE at the sprag clutch housing and/or oil spray nozzle may lead to blockage of the nozzle. This could lead to inadequate cooling and possible damage to both of the generators.
The classification of this mandatory Service Bulletin has been changed to a mandatory Alert Service Bulletin due to the fact that the failure mechanism has been re-evaluated to include immediate action as described before flight!
