  "textContent": "A planet gear housing assembly is disclosed in an epicyclical gear system of a gas turbine engine having an engine casing. The planet gear housing assembly comprises an aft planet carrier assembly, a forward planet carrier assembly, and a plurality of planet gears. An aft flange of the aft planet carrier assembly is coupled to the engine casing to define a first torsional stiffness. A forward flange of the forward planet carrier assembly is coupled to the aft flange to define a second torsional stiffness. The second torsional stiffness may be between 60% and 80% of the first torsional stiffness. The planet gear housing assembly may further comprise a stiffening member positioned between the forward planet carrier assembly and the aft planet carrier assembly.",
