Hung,
I don't know if this would carry over but logic would dictact that it does:
When I bought a factory new engine for the split tail 2 1/2 years ago, Continental told me a full 1/3 of the price of the engine was for liability insurance.
Now, he may have just said that to make the pill easier to swallow or to divert my attention of the total dollar amount away from Continental (the blame game) but if he was shooting me straight, would not the same ratio carry over to the airframe side?
