Certified O320 overhaul question
Curious, for a CERTIFIED engine I'm overhauling, must the crank and cases be sent out and tagged to call it "0" SMOH? (Not 0 total from factory)
If I mic everything and all tolerances, fits and clearances are within table of limits on all pieces, soft metal too, can I call it an overhaul, with the list of "arbitrary replacement" pieces changed too of course...ie...crank gear bolt, small rod end bushings etc
I can even use dye penetrant on case and crank and rods etc plus visual inspections with 10x glass.....and follow every direction in the overhaul manual and check all applicable SB, LETTERS and ADs.....can I theoretically put it all back together and call it 0SMOH?
Or is there something about the Certification process that can only be satisfied by it going out, being tagged and then put back together that legitimately then can be considered a 0smoh engine?
I don't see anything that requires a specific inspection such as magnetic particle on crank or rods either.
Not looking for "not wise" or other subjective answers, just purely respect to regs please. Any info appreciated.
