You do wonder at times with some of the items they have had big big stuff ups with on the 912 engines most after 2000 cam shafts, engine crank casing fretting ,models failing , fuel pumps failing and list go on . All this tends to happen when you out source you parts to the very very cheapest manufacture they can find . They add 1000 percent to there spare parts cost and charge the customer full ticket plus more to teach them a lesson on for owning a plane even if they can,t make those over priced part right in the first place . I seen guys spend $12 000 on parts on engine that have only do 600 hours due rotax crank casing stuff ups . I remember back in the old 503 days you where lucky to get 150 hours before the cranks broke right throw . 4 designs later to fix the problem obviously the owner of the company never flew behind one or it would have been fixed first go .
