An aircraft engine has a gearbox having a casing defining an internal chamber and a scavenge port. A gear is rotatably mounted inside the internal chamber for rotation about a rotation axis. The gear is axially spaced from the scavenge port. A baffle is disposed inside the internal chamber. The baffle includes a perforated plate disposed radially between the gear and the scavenge port relative to the rotation axis. The perforated plate has a first portion extending around a portion of a circumference of the gear, and a second portion extending axially away from the first portion over the scavenge port of the scavenge area.
