a. SOURCE CODES appear on APL/AELs and will
consist of two digits entered in the first and second positions
of the SM&R code indicating the manner of acquiring
support items for maintenance, repair, or overhaul of items.
Specifically, these codes indicate whether the part is to be
procured on demand and carried in the supply system,
manufactured, obtained from salvage, or assembled with
component parts. They also indicate if the part is not to be
replaced due to the practicality of installation of the next
higher assembly or impracticality of replacement. Failure or
damage of the part indicates a requirement for complete
overhaul or scrapping of the assembly or equipment. (DEN
