However, after 30 years of dealing in these engines, and the Russian keenness for paperwork we literally have thousands of pages in our archives and I couldn't immediately find it without spending a lot of time. However, surely these hours, whether over- conservative or not, are so widely known, and indeed I suspect the only interest people have is to increase the permitted hours in those countries where they have to be followed. Unless things have changed significantly at Shakty, I am sceptical of the quality of work coming out of any Russian factory. Over the years, I have visited all the factories - OKBM; Voronezh Manufacturing Plant; Veenitsa; Shakty, and the common problems they all have today are that they are under-funded; occupying large and very expensive to run factories as well as being very short of parts. In particular Voronezh, which was the central source of spare parts, sold everything related to M 14 engines last year. You're lucky if you can operate your engines on condition - in Europe we have to follow the strict manufacturers figures - mind you I'm always rather sceptical of the hours in the aircraft logbooks of private owners! We have had similar problems in Europe in that we had been using a "Mickey Mouse" Russian registration which, about 14 years ago the various European authorities declared (and quite correctly) as being illegal. Effectively this would have grounded most Yaks and Sukhois in Europe. Fortunately I had a friend running certification at EASA and he created a completely artificial category of "restricted certification" for all Sukhois; Yak 18T/54/55. I suspect that is where your authorities have come up with your legislation. Then the non-certified aircraft like 50; 52 were left for the individual national authorities to decide whether to accept them or not, and the majority of countries don't accept them, although in a number of cases they will accept the aircraft if they have some form of restricted or experimental registration from another country - a total lack of coordination.

Do you have any of the OKBM data you refer? I wasn't questioning the quality, merely the scope of the work. I had the privilege of going to the Shakhty overhaul facility a bit over a year ago and I had a good look at their operation. I have been a Licenced Aircraft Engineer for many years now and I have worked at many places all over the world. I can honestly say that the Shakhty plant is old, and not very impressive looking, but it was clean, tidy and as far as the work they turn out and the skill of the guys who work there goes, they would hold their own with anything I have seen elsewhere else. And yes, I agree totally with your comments about engine life. I have been told that the air race guys never even make three digits with their engine lives!. We have set overhaul periods for components here in NZ like anywhere, but for non-commercial operations we are allowed to run our engines on condition until it is out of limits (leak downs, oil consumption, SOAP etc), even then a cylinder change can sort most of that. The reality is that all engines are on condition all of the time. If a new engine starts making metal, or shows other signs of distress you deal with it the same as you would an old one. The issue I am having is that our CAA have put these planes into a Restricted Limited category which means they treat them as a certified aircraft built to a standard, they just don't know what the standard is. Because manufacturers data is scarce or unobtainable, Chinese whispers (sorry CJ6 guys) and Facebook seem to be being held up as gospel. Add into the mix the difference in manufacturing and regulation philosophies, the breakup of the Soviet Union and the language barrier and my frustration levels rise. What I think I am hearing is that I am just going to have to suck it up, accept that there isn't a right answer and make the most of it. Now, where are my OCD pills....?
