Early next year Boeing will offer a kit for BBJs and BBJ2s that will provide a 6,500-ft cabin at FL 410 instead of the standard 8,000-ft cabin. The kit, which can be installed on green and in-service BBJs, is expected to cost less than $100,000. Components include new cabin-pressure-controller boxes with revised software, a new cabin-altitude indicator and two pressure-relief valves. Installation of the kit can be made by certified mechanics, completion centers or Boeing. No structural changes are necessary and no special maintenance will be required until the airplane surpasses 30,000 flights.
