A forward frame comprises a plurality of vanes radially across the gaspath. A torque box (186) couples the fan case vanes (44) to the forward frame. A transmission (46) couples a shaft (25) to a fan shaft (132) to drive the fan (42). A fan bearing assembly (150) couples a stationary forward hub structure (152) to the fan shaft (25).",
