Buying R44 with expired TBO and/or calendar?
I'm not a helicopter guy though flying rotary (gyros) for almost 20 years. Recently a local guy asked what can be pros&cons in purchasing an R44 with expired TBO and/or calendar to fly it without type certificate under local "experimental" category. We're in Russia and he just wants to fly privately within, say, 100 miles from his nest for his own pleasure. Is there any sense, I mean can such helicopter be operated safe if it expired TBO hours on engine and blades, or if it has over 12 years since main overhaul?
Any suggestions are greatly appreciated.
