Our problem in the UK was that we historically operated Yaks on the Russian or Lithuanian registers. About four years ago our CAA decided that these were not acceptable for international flight and said that those that were "ex-military" - i.e. 50 / 52 (until the end of '92!) and 55 chould be operated on a UK "Permit to Fly" - sort of equivalent to US "experimental".
However they then became aware of the 500/600 hour total overhaul requirement. Initially they insisted on us doing this, which clearly is an economic impracticality, but after long meetings with Yakolev in Moscow I got them to agree to replace the total overhauls with a detailed inspection procedure, at 600 hours (or 15 year intervals) in which wings are removed; tail removed; engine out and all parts magnaflaxed /x-rayed etc.
Administratively it is still a nightmare since all results have to go back to Moscow, and the processing very slow, but at least they do not have to have the total overhauls.
For all 52 owners, and particularly the those who fly the aircraft hard I would have thought it prudent to follow these inspection procedures, even in countries where you do not have to!
