Rumour has it that that particular aircraft was burning a very high rate of consumption of oil in the lead up to the event, of which maintainance were aware but of course did very little about it. So it is quite possible that the pilot took off with less than 9.5 quarts, but for a normal running engine to fail after a 2 hour bungle flight he would have had to take off with less than 3 quarts. Which leads me to my point that this never would have occured if the engine was consuming normal ammounts of oil, and every pilot who works at gator knew it was burning high amounts.
but its fine "go and fly it"
