Abstract
A system and method for dispensing a sealant over aircraft fasteners secured to a surface in the aircraft. The system includes a nozzle tip having a shroud configured for placement over the fasteners. Sealant is metered to the shroud via an orifice within the nozzle tip. The shroud is sized to leave a space between it and the fastener to control the amount of sealant applied to the fastener upper surface and along the interface between the fastener and aircraft surface. Pressurized fluid urges the sealant through the orifice.
