Helicopterhelp: It already exists to a cetain extent vis a vie independent audits. We employ a consultant engineer to audit us i.a.w. part M. even though we dont need a CAM in our industry currently as we are exempt.
What you are advocating is the role of an independent auditor with a commercial hat on - yes?
Could work, should work...but only for those who aren't savvy with the business your describing (which tant amounts to all private flyers and small AOC operators - seems to me once you get to a critical size...or use public money....no-one notices the extra 'zero' on the end of the bill
Good luck to you....I think you've found a crack in the system.
