In 1972 I flew a C182, (VH RFK), out of Orange circa Hazleton's.
The aircraft had a distinct odour having been converted from taildragger ag work into nosewheel. It stands to reason that there is an AD somewhere to turn it back into a taildragger.
Just a suggestion, but if so, there are a few good C180 and 180A models around with straight tails that would save lots on rebuilds to achieve the same thing. I've seen this done with straight tail turtleback 150's and they are a pretty conversion. Even saw one with a 150HP engine. I think that bloke used it for mustering.
The swept tail tailwheel conversions don't cut the mustard in my view.
