I think the point has been made that the editorial costs, including print ready galleys (PDFs these days), are covered by the advertising. This just leaves the printing and distribution costs to RAA accounts, around $440,000 if my memory serves me. The difficulty with the RAA accounts and budgets is that they reveal little information about the activities funded such as Licencing (certificates), Operations, Technical, Advocacy, Safety, Training, Secretariat, Publications, Other administration etc. The failure of the Audits would have lead to some very hefty expenses under Technical, borne by all members rather than just aircraft owners or even the subclass where the problems arose.
