A fan blade secured is to the hub. A platform is removably secured to the hub and is arranged adjacent to the fan blade. The platform has a body with lateral sides that each include a channel. A seal is re­ movably received in each of the chan­ nels, with one of the seals abutting the fan blade. A method of repairing the fan blade platform includes the steps of re­ moving a nose cone to provide access to a hub, detaching a platform from the hub, and pulling the seal from groove a in the platform.
