When a rivet length is not specified, length must be determined by the installer. In some instances, vendor part
numbers are also used.
“X” indicates part is available as a separate spares item.
“O” indicates part is no longer available , or only available as part of a higher assembly.
Change bars are located on the outside edge of the page, and indicate new or revised data. Change bars
between lines indicate data was removed, and parts renumbered as required. Change bars on figure pages
indicate changes to the figure somewhere across the page in the area of the change bar. A change bar
encompassing the figure title and item 1 indicates the figure number changed. Change bars that are the full
length of the page indicate all new data, usually a new figure and parts data.
