Abstract
An accessory driving apparatus for an aircraft system is connected to an accessory unit to be driven, such as a PCU pump. A gear set for transferring rotational power from the driving shaft to the driven shaft is provided for selective arrangement in first and second configurations in order to permit the driving shaft to rotate in either rotational direction without affecting a predetermined rotational direction of the driven shaft.
