Abstract: A method and apparatus for operating an aircraft. The aircraft is flown. A skin panel is held on a support structure. The support structure has flanges on a number of edges of the support structure, the flanges being substantially orthogonal to the edges. The support structure also has openings into the support structure substantially orthogonal to the flanges. First connecting structures on clips are connected to the flanges and positioned such that an opening in each clip is aligned with one of the openings in the support structure. The skin panel is positioned such that the clips are received in holes in the skin panel. Fasteners are attached to the second connecting structures such that the support structure holds the skin panel.

Abstract: A waterproof grounding connector is securable to a grounding surface and capable of receiving a plurality of electrical terminals in a sealing relationship. The waterproof grounding connector includes a connector body having opposite first and second ends, and a plurality of parallel longitudinal chambers extending through the connector body. Each chamber is adapted to receive an electrical terminal. A lock means is provided to secure the electrical terminals within the chambers. A hollow, peripheral shroud is located at the second end of the connector body and defines an enclosure having an internal peripheral surface. A flexible grommet with a continuous peripheral edge is adapted to be inserted into the shroud enclosure and creates a continuous peripheral seal between the grommet edge and the internal shroud surface. The grommet includes a plurality of slots which correspond to and align with the chambers.
