    Abstract: An actuation system (44) for controlling a first door (38) and a second door (40) includes a first actuator (72) having a first interior passage (74) and a second actuator (76) in line with the first actuator (72). A first shaft (82) extends from the first actuator (72) and has a second interior passage (86).
