Abstract
There is disclosed a bearing assembly for a gas turbine engine including at least two bearings axially spaced from one another relative to a central axis, and a squirrel cage secured to a casing of the gas turbine engine. The squirrel cage supports respective bearing loads of the at least two bearings. The squirrel cage has a frangible section between the bearings configured to preferentially fail upon application of a load greater than a preselected threshold bearing load.
