I have run out of my free time slot for the online flowchart software and I do not plan on purchasing it
so I have to consider it "finished", for now anyhow ...... I tried to cover as much as I could while considering
as many different "fixes" as I could with the available information that I had at my disposal

its not perfect, but better than nothing to work from, and I consider the chart for "Workbench Use"

first one is piston, second is DI

the image shows a bit small on screen (its in .png format),
I suggest saving the image to a file and printing it out as large as you can
even if it takes several sheets of paper to get it large enough to easily read
if someone can host it to post it in a .pdf file format I can email it to them in that format, just ask





and here is the DI chart

Darn hard to read the small print...

First step is Tap, Roll & Rack.

Replace the magazine.

After that Chapters 2 and 3 of TM9-1005-319 -23&P list the following steps:  (The magazine is the weak point here.)

1.  Magazine catch spring weak or broken.  
2.  Magazine catch defective.
3.  Magazine catch our of adjustment.
4.  Short recoil.

Short recoil:
1.  Improper, worn, missing bolt rings
2.  Bent or broken gas tube.
3.  Gas tube spring pin (roll pin) missing from front sight.
4.  Plugged gas system due to carbon build-up in the gas tube.  (Replace gas tube and clean area inside the front sight.)

(TM is public domain and downloadable several places.)

Are you going to write a program.  make it open source, collect inputs from class instructors.

I would not let the first decision to be made a function of maintenance.  In the end you need a way every part fail and a path for it.
