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, appear 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   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. REVIEW NUMBER 2 Q1. During  a  weapons  inspection,  you  find  a weapon   or   component   that   doesn't   meet inspection criteria. What is the first step you should take? Q2. What    is    the    maximum    weight    you    are authorized to manually load/download? Q3. When   manually   loading   GP   bombs,   what hoisting bar should you use? Q4. If  a  sway  brace  on  a  bomb  rack  isn't  being used, it should remain in what position? Q5. What  is  the  maximum  tightening  range  of  a sway brace screw? Q6. When you begin dearming an aircraft, what is the first step you should take? SAFETY PRECAUTIONS LEARNING OBJECTIVE: Recognize the safety  precautions  to  follow  when  loading  or unloading aircraft. Safety  precautions  were  given  in  this  chapter  as WARNINGS,   CAUTIONS,   and   NOTES.   However, there   is   other   safety   precautions   that   you   should observe  when  loading  or  handling  aircraft  bombs  and practice bombs. A few of these safety precautions are as follows: ·  Before    removing    aircraft    bombs    from    the weapons staging area, verify that the bombs are properly secured to the handling equipment. ·  Aboard  ship,  when  the  bombs  are  delivered  to the aircraft for loading, they must be positioned fore and aft to help prevent inadvertent movement  of  the  handling  equipment  by  the side-to-side roll of the ship. ·  Once bombs have been delivered to the aircraft, a  person  must  remain  in  the  immediate  area. Bombs   must   not   be   left   on   the   flight   deck unattended. ·  Never attempt to load/download bombs without sufficient personnel. ·  When   installing   signal   cartridges   in   practice bombs,  never  assemble  more  bombs  than  are needed for the next event. When the day's flight schedule  has  been  completed,  practice  bomb signals  must  be  removed  from  practice  bombs before returning them to storage. ·  Because  of  the  nonexplosive  nature  of  practice bombs,  AOs  have  a  tendency  to  be  lax  when handling and loading practice bombs. Remember,  a  Mk  76  practice  bomb  weighs  25 pounds and could cause severe injury if dropped on a person's foot or hand. Additionally, when a practice bomb signal is installed and the bomb is accidentally  dropped,  sufficient  fire  and  metal 14-12
