Claim:
1. A fan drive gear system comprising: a sun gear rotatable about an axis of rotation; a plurality of intermediate gears rotatable about an intermediate gear rotation axis in meshing engagement with the sun gear; a ring gear circumscribing the intermediate gears; a bearing assembly supporting at least one of the plurality of intermediate gears, the bearing assembly including a first beam, a second beam and a bearing surface, the first beam extending axially in a first direction from a support structure to a first end spaced axially from the support structure, the second beam extending from the first end of the first beam in a second axial direction that is opposite the first direction to a midway portion of the bearing surface, and the bearing surface is supported on the second beam, wherein both the first beam and the second beam include an approximately common stiffness and bend in opposite directions to maintain the bearing surface substantially parallel to the intermediate gear rotation axis under a load applied to the bearing surface during operation.
