The planetary gear system (48) includes a plurality of planet gears (82) surrounding a sun gear (74). A carrier (90) supports the plurality of planet gears (82) and includes a first carrier bearing flange (128). A ring gear (108) surrounds the plurality of planet gears (82) and includes a ring gear bearing flange (124). At least one ring gear carrier bearing (130) engages the carrier bearing flange (128) and the ring gear bearing flange (124). A speed change mechanism (48) for a gas turbine is also disclosed.",
