That's true in many cases. At the rate things are going, I expect to need a new prop
in about 30 years (if I don't get a prop strike before then).

Then we also have to deal with certification issues. The manufacturer has only
certified my aircraft for one prop. I suppose that STCs would be developed pretty
rapidly if 3-blade props were mandated, of course.

And if they were mandated they'd probably run between $1,000 and
$2,000 each plus the cost of the prop and labor.
