A gas turbine engine accessory (20') is removably mounted to a gearbox (30') of a gas turbine engine (10). The accessory has a drive shaft (35) extending into the gearbox (30'). A driven gear (36a') is mounted on the drive shaft (35). The driven gear (36a') is adapted to directly engage a drive gear (40') of the gearbox (30'). The purpose of this improved design is to lighten the overall weight of the gas turbine engine by reducing its number of parts and components.
