Tuc,
I know Chug and I are not far apart - the issues he sees as needing to be dealt with are valid issues, and the support issues you detail also affect the bottom line. However, as Soddim has acknowledged, parcelling them all up as "airworthiness" isn't the answer.
In many of his posts, Chug looks to the CAA model, however, it isn't the Civil Airworthiness Authority, but Civil Aviation Authority. And byond our shores Airworthiness is seen as a subset of Safety.
So, I have no problem with ensuring that all Chugs concerns are addressed, but not under the single banner of Airworthiness.
