A rib foot cleat for sealing around a stringer 14a passing through a rib mousehole (16, figure 2) in an aircraft assembly 22. A rib foot cleat body 24 for attaching to a rib 12 at a rib mousehole, defines a cleat channel (34, figure 4) configured to be arranged over the stringer. An injection hole 26 is in fluid communication with the cleat channel, allowing sealant material injection through the injection hole into the cleat channel for sealing around the stringer. The cleat channel may be U-shaped and terminate at a first channel opening rim on one side of the cleat body and at a second channel opening rim on an opposite side of the cleat body, and comprise a channel lip 56 extending at least partially around the cleat channel interior adjacent the first and/or second channel opening rim. The channel lip may delimit the injected sealant material.
