WARNING Do not remove a fuze or arming wire that was not installed during loading procedures. Do not remove an arming wire unless the fuze safety pin or device is installed. Ensure that the M904E3/E4 fuze is safe by verifying the installation of the arming wire in the arming wire guide and the arming vane. Make sure you can’t see a black letter A against a red background in the upper (external) window. If the arming delay isn’t set on 6 or 18 seconds, the upper (external) window should be vacant. If the arming delay is set on 6 or 18, you should see matching numbers on a green background in the window. Then, you can install a safety wire through the arming wire guide and the arming vane. WARNING If the arming wire is not in place or if the upper (external) window indication is a black letter A against a red background, the fuze is armed. Do not attempt to change the arming delay settings to disarm the fuze, or to remove the fuze from the bomb. Notify the proper authority (EOD) when an armed or partially armed condition is indicated. WARNING If a green background without the number 6 or 18 appears in the upper (external) window when the arming delay is set on 6 or 18, or if the number in the upper (external) window does not match the arming delay setting number, the fuze is partially armed. Notify the proper authority. Other actions you should take when unloading weapons include checking to see that the arming wire is installed in the pop-out pin for Mk 344, Mk 376, and FMU-139 electric fuzes. If an electric fuze was used, you need to disconnect the Mk 122 arming safety switch lanyard tab from the spring latch. Then, if applicable, install the fin release band safety (cotter) pin. Disconnect the fin release wires, lanyards, and arming wires from the aircraft. If applicable, you can remove the M904E3/E4 fuzes by installing a safety wire, and then removing the arming wire and removing the fuze from the bomb. After you have removed the fuze, make sure the lower window is vacant or dark colored. Set the arming delay to 6 or 18 seconds. Then, make sure a green background with a white number 6 or 18, depending on the arming delay setting, appears in the upper window. The lower window must remain vacant or dark colored. WARNING If the lower window is red or has a black letter A against a red background, the fuze is armed. Notify the proper authority (EOD). NOTE: Each fuze must be checked for safety on the 6- or 18-second arming delay setting before it is returned to the weapons division. Now you’re ready to position the handling or loading equipment under the station you want to unload. As applicable, install a manual hoisting bar or a bomb hoisting unit. Retract the ejector foot to the full up position. Then, retract the sway braces to the full up position. Position the required number of personnel at the front and at the tail of the weapon to steady and guide the weapon onto the bomb handling equipment. Raise the weapon until the suspension lugs float in the hooks. Remove the parent rack safety pin, or move the IMER/ITER safety lock lever from lock to unlock, as appropriate. Operate the manual release to open the suspension hooks and lower the weapon onto the handling or loading equipment. If an electrically fuzed bomb is being unloaded, lower the weapon approximately 4 inches, and then disconnect the Mk 122 arming safety switch quick-disconnect connector from the rack Then, you can lower the weapon to the handling or loading equipment. Properly secure the weapon to the handling or loading equipment. When all weapons have been unloaded, remove the WEAPON LOADED sign from the cockpit. Then, remove all weapons and handling or loading equipment from the area. Finally, report the status of the aircraft to the proper authority. Q1. Q2. Q3. Q4.
