C. Effectivity
The applicability of a particular part of its primary assembly is indicated by a code
letter or letters in the "USAGE CODE" Column of the PARTS LIST. Normally,
when four or less primary assemblies (initial entries) are broken down in an
individual list, the code letters assigned to each primary assembly are listed
opposite an individual part to indicate its applicability. When five or more primary
assemblies are broken down, a double alphabetical letter is included in the
"USAGE CODE" Column and an explanation of the code letters used is included
as the final entry of the list. If no entry is made in the "USAGE CODE" Column,
the individual part is common to all primary assemblies listed.
