Give me a break. I can't imagine that there really exists aircraft
owners out there that don't already know this stuff. How could anyone
own an airplane and not already be familiar with this? If someone
really thinks its legal to buy a belt from an automotive shop and put
it on their plane, you wonder how they ever had the intelligence to
pass the PP written. I always bring my service manuals out to the plane
when I'm doing any kind of work (including oil changes).
