Russian Overhauls
There is quite a lot of confusion about this, and clearly Western use is
rather different to original Soviet. Of course everything was operated
in a
military environment; no concern about cost.
Engines
=D8 The M14P had a 750 TBO when a new engine. It was then allowed
three
overhauls, each giving a further 500 hours, for a total =93Life=94 of
2,250
hours ' at the end of that the engine was melted down.
=D8 Because the use was very standardised, there was a set of standard
overhaul procedures, depending which overhaul it was. For example first
overhaul would normally only have oversized piston rings, but keeping
the
original pistons. A second and third overhaul would have oversized
pistons
as well. However the important point was that the engine was expected
then
to deliver factory new power for the next 500 hours.
=D8 Also new engines had a =93shelf life=94 of 6 years, and after this
were sent
back for a strip down; new seals and gaskets; check for corrosion etc.
=D8 Maintenance at airfields did nothing more than change the big
cylinders.
Anything more than this; ground strikes etc all meant the engines
returned
to one of the few factories for total overhaul.
Airframes
=D8 Depending on which type of aircraft, all had a =93Service Life=94
to first
overhaul. So for a 52 this was 600 hours, after which the aircraft
would be
returned to the factory for TOTAL overhaul to new condition. This meant
that EVERY component was stripped out of the aeroplane; either
overhauled or
replaced with new; aircraft built up again as a new aircraft.
=D8 For 52s total life (i.e. three overhauls) was 1,500 hours, and has
not
been officially extended, although clearly, in Russia, a number have
done
more than that.
=D8 These military style total overhauls are still being done by
Aerostar,
the original manufacturer.
=D8 The 50 was always intended as a short-life aircraft, with a total
life of
300 hours, and no intention to overhaul or extend.
=D8 The 18T had a major overhaul at 1,500 hours, and a total life of
3,000
hours.
Under current use, of course all of these hours are significantly
extended
and stretched.

The -XDK suffix I have not seen before. Although the Western flange and the fancy
paint hob is, I know, available from all the regular places, the "-XDK" designation
is, I think, nothing more than a marketing invention.
A question I would ask, as my a/c is on an EASA (restricted-)Certificate of Airworthiness,
is whether the engine is allowed to be fitted to my certified aircraft.
And, if so, what is the TBO. It will not be 1500 hrs. If only!
