Zusammenfassung:	A single drive, dual clutch accessory drive system (20) for an aircraft including an input shaft (66) connected to a low pressure spool (49) of a turbine engine. The input shaft (66) is rotatable at a first input speed and at a second input speed that is distinct from the first input speed. An output shaft (70) is operatively connected to an aircraft accessory (40). A first drive path (74) operatively connects the input shaft (66) and the output shaft (70). The first drive path (74) includes a first clutch (50) and a gear system (80). The first drive path (74) is operable to adjust the first input speed to a selected output shaft speed. A second drive path (76) operatively connects the input shaft (66) and the output shaft (70). The second drive path (76) includes a second clutch (88). The second drive path (76) is operable to rotate the output shaft (70) at the second input speed.
