Abstract
A method of performing maintenance on an aircraft engine includes removing a propeller shaft of the aircraft engine to form an access volume at a center of the aircraft engine. The access volume extends axially and radially relative to a center axis of the aircraft engine. The method includes performing maintenance on a lubricant strainer positioned at a location of the access volume where a carrier of the aircraft engine engages an output of the aircraft engine.
