I sold a Cessna 172N to a client, who exported it for use in Japan. Nearly a year later it was brought back, as the hurdles to putting it on the register and operating in Japan became impossible to cope with. As an example,
no non standard parts were acceptable in the aircraft: even the radios, transponder and seat belts, which had been legally replaced with newer/better items, would not be allowed on the aircraft for Japanese registration, and were required to be reverted to stock Cessna parts
A number of R44's were hired on a high use operation, and still came in at double the Australian rate. Maybe, just maybe, they have the sums right, and we should look at our charge rates being too low
