Texas Mooney

Who is "Mark"? Can you elaborate on your statement "Mooney will not buy externally sourced parts any more"?

I found the docket with the pilot report and ferry permit using your link and the tail number. In the pilot report under Fuel & Services Information it says that the engine did not run well on the morning of 10/30/2023 and that he replaced the engine driven fuel pump which ran well after that. That is the same day of the 4-5 hour accident flight to Colorado. There is no mention of a test flight after changing the fuel pump. Continental engines require the SID-97 fuel system test and adjustment after fuel pump replacement otherwise anything could be off. The performance and fuel parameters he saw on the prior days and legs could be meaningless. And ther ferry permit says he could only fly in daylight. Does anyone know how long it takes to change the engine driven fuel pump on a Continental in a K? That is one crazy long day racing against sunset. A leak from working on it or just the new pump could have caused this besides not leaning.
