I’m aware of the “low production rate”, “weight”, “limited market”, and “extreme elements” arguments in defense of the complexity of GA production but I’m left unconvinced. Any better explanations???
Well, those are all good reasons, but another important one is certification - we might pay several times the price for inferior equipment, but at least we know it’s FAA/JAA/CAA/CASA certified!
Seriously, the cost and complexity of certifying anything new means we get stuck with old technology. Add that to the reasons you listed above, and the end result are expensive, handbuilt and unreliable aircraft.
Counter to that, most of the problems that have arisen with the Cirrus SR2x are in the components that Cirrus buy from outside - engines, accessories and avionics. The airframe has had surprisingly few problems, given that it’s new.
