Gas turbine engine front center body architecture

A gas turbine engine comprising:

• a propulsor including a plurality of blades;
• a geared architecture including a gearbox;
• a first spool including a first shaft interconnecting a first turbine and a first compressor, and the first compressor includes a compressor hub and a disk extending from the compressor hub to support a plurality of compressor blades;
• a front center body assembly defined around an engine longitudinal axis, wherein the front center body assembly defines a portion of a core flow path through the gas turbine engine that is upstream of an inlet to the first compressor;
• a flex support that supports the gearbox relative to the front center body assembly;
• a bearing support including a bearing package mounted to the front center body assembly and the first spool, wherein the bearing package engages the compressor hub at a position forward of the disk relative to the engine longitudinal axis;
• a front wall mounted to the front center body assembly;
• and
• wherein the front wall is removable from the front center body assembly to access at least one of the gearbox or the bearing package.
