A gas turbine engine comprising:

• engine static structure housing a compressor section, a combustor section and a turbine section;
• a spool supporting at least a portion of each of the compressor and turbine sections for rotation about an axis;
• a gearbox supported by the engine static structure and coupled to the spool by a tower shaft, the gearbox comprising:
• a housing including first and second housing portions interconnected by an intermediate housing portion to provide a generally U-shaped structure, each of the first and second housing portions including opposing first and second faces, the second faces of first and second housing portions adjacent to one another;
• first and second gear sets respectively arranged in the first and second housing portions, and a third gear set arranged in the intermediate portion and coupled to the first and second gear sets;
• an input shaft interconnecting the tower shaft to the third gear set;
• and
• accessory drive components mounted on at least three of the first and second faces of the first and second housing portions, each of the accessory drive components coupled to one of the first and second gear sets, the accessory drive components arranged circumferentially about the engine static structure with respect to the axis.
