An apparatus and method for installing an aircraft bulkhead connector with a bulkhead is disclosed where access to only one side of the bulkhead is required. The disclosure is also applicable to installation of bulkhead connectors in aircraft fuel tanks. An aircraft bulkhead connector and installation tool is also disclosed. The bulkhead connector includes a female end portion and the installation tool includes a male end portion. The male end portion of the installation tool is removably engaged with the female end portion of the bulkhead connector, such that the installation tool protrudes beyond the female end portion of the bulkhead connector. The installation tool may be inserted through an aperture in a bulkhead and used to both position and hold the bulkhead connector during the installation process.

The present disclosure is related to a device 100 configured for aligning a first hole 131 of a first flange 130 with a second hole 141 of a second flange 140. The device 100 comprises a base 101, a shaft 110 extending from the base 101 and a first and a second pusher 115, 116. The shaft 110 is configured to move between a retracted position and an extended position. The shaft 110 in the extended position extends from the first hole 131 into the second hole 141. The first and second pushers 115, 116 are also configured to be moved radially outwardly from the shaft 110 to exert pressure against an inner wall of the first and second holes 131, 141. Methods for aligning a first and a second hole 130, 140 are also provided.

A flange manipulating device for installing and removing flanges includes a bar that is flat. Each of a pair of first holes that is positioned through the bar is positioned proximate to a respective opposing end of the bar. A coupler is coupled to and centrally positioned on the bar. Each first hole is configured to selectively align with a respective second hole that is positioned in a flange. The first hole and the respective second hole are configured to insert hardware, such as a bolt to couple to a nut, to couple the bar to the flange. The coupler is configured to couple to a tool, such as a wrench, to position the tool to selectively applying torque to the bar. The bar is configured to transfer the torque from the tool to the flange to selectively install the flange on and remove the flange from a threaded pipe.
