Here is what I have learned. The TBO on the M-14P is..... I still don't know! Does anyone have any data from Vedeneyev themselves? I have not been able to find an official manufacturers TBO. DOSAF did their first overhaul at 750 hours, then 500 hour intervals and retired the engine at 2250 hours. As they were essentially the only operator of these aircraft it seems these times have been accepted as though it was from Vedeneyev themselves. All the overhaul facilities for the M-14P I contacted have adopted these figures as well. Remember that they worked only for DOSAF, and of course it is to their commercial advantage to have these engines overhauled more often. Their definition of "Overhaul" differs from ours too. Again, I have not been able to find any official data, but their overhauls seem to align more with a "Survey" of an engine that is common in the marine industry. Essentially a bulk strip, inspect, replace the stuffed bits and stick it back together. In the military we used to call this an IRAN - Inspect And Replace As Necessary. The lubricants we use are generally better than what these engines used to run on. The dude at Termikas told me that the Wilga engine TBO is increased from 800 to 1000 hours if it is run on Aeroshell 100. Given that Jill from M-14P said she has seen well looked after engines with 2200 hours TSO on them seems to reinforce our oil quality and just how robust these engines are too. Again, no official data! Wikipedia reigns supreme!
