Sadly, there is also a supply chain for counterfeit parts.
There was a joke around corrosion corners years ago:
"I want that R-1820 there."
"Okay, and how many hours do you want it to have?"
This is kind of going away since making a profit with a DC-3 is not all that likely anymore.
Happiness is not seeing another trite Ste. Maarten photo all week long.
