|
|
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!�
