Zusammenfassung:	A spark containment cap for forming a sealed cavity around an end of a fastener protruding from a structure, the cap comprising: a cap body defining an air cavity arranged to enclose the end of the fastener, and including an annular base terminating at a base rim which surrounds an opening into the air cavity; and an annular skirt to provide an annular sealing volume extending around the base rim arranged to receive an annular bead of a curable sealing material around the opening into the cavity to provide a seal between the cap body and the structure to seal a volume of gas within the cavity. The cap further comprises a fastener engaging portion that engages with a threaded portion of the fastener so as to secure the cap to the fastener.
