I carried out some “due diligence” in this respect on a particular airframe that came up for sale and discovered that it had apparently been flying with its first owner for two years with the C of G over 4” outside the aft limit!
This made no sense whatsoever. I suggested the aircraft was re-weighed and discovered that the factory figures in the tech log were very much incorrect. Having done that and re-calculated, the actual C of G was actually right in the centre of the envelope.
No harm done but it just shows that no one else had bothered to actually check the weight and balance, even at the factory.
