The problem is that the FAA doesn't have the expertise. The people with the expertise all work for aircraft manufacturers. And odds are the FAA will never pay anyone enough to leave the manufacturers to do the job.
Pass regulation that requires audit and certification by a rated and licensed authority that isn't necessarily the government itself. As a publicly traded company Boeing already has to do this with its books; why not with its product too?
I'm sure that E&Y, Deloitte, KPMG, or PwC would love a crack at a new market and they've certainly got the money to hire away from manufacturers.
