Cessna has asked the FAA to allow the Citation CJ4, being certified under Part 23, to meet the lower landing gear ground loads of Part 25. The reduced ground loads under Part 25 will result in an overall weight reduction of 36 pounds. “A 36-pound reduction per aircraft can provide a 0.24-pound fuel saving over a typical flight,” Cessna said. “Based on an estimated business jet usage of approximately 495 flights per year, this corresponds to an estimated annual fuel saving of 118.8 pounds per aircraft. With a conservatively estimated fleet size of 533 aircraft over the next decade this would yield an overall fuel saving of 63,320 pounds per year.”
