My question is: "How many automotive oil filters do you know of that have
fallen off?" I don't know of a single one.

Some of the things we safety in aviation vs some of the things we don't are
pretty interesting.

For instance, we don't safety the AN fittings on fuel and oil lines. Why
not? What makes these different from the oil filter?

I've heard of it happening, although it never happened to me.
Airplanes aren't like cars though, they have a prop which causes a LOT
more vibration than the engine in a car experiences. That's why oil
filters on airplane ARE safety wired.

You haven't driven much on "salt belt" highways, eh??
Washboard/frost-pocked roads are rougher than a LOT of aircraft!

AN fittings are different from oil filters, they are a lot smaller and
you really crank them on the threaded fittings. They don't have the
same mass as an oil filter and because they are flexible, they don't
experience the same vibrational frequencies. Or at least that's my
take.
