Mounting arrangement for gas turbine engine accessories and gearbox therefor

Gas turbine engine accessories (75 ... 100) are mounted on an accessory gearbox (60) therefor which is in turn mounted on a case (57) of the engine (5) such that the accessories (75 ... 100) extend from the gearbox (60) in directions generally parallel to circumferential tangents to the engine case (57) for compactness, ease in installation and removal of the accessories, reduction of the weight in lines extending from the accessories and minimization of the risk of damage to such accessories and gearbox from the fan blades which may separate from a fan hub upon encountering birds, ice, or other foreign objects.
