A shroud panel is removably joinable inwardly of a fan casing and outwardly of a fan blade in a turbofan gas turbine engine. The panel includes an arcuate backing plate having a plurality of screws disposed therethrough for mounting the panel to the casing. Each of the screws includes a locking ring joined to the shank thereof and spaced from the screw head for allowing limited translation of the screw through the panel while preventing its liberation therefrom.
