data for engine speeds near redline, the only time my Mooney sees anything
like
that RPM is at takeoff.

Same here, but that's not the point. The question is not whether it's
economical to operate at redline for extended periods, but whether it's
*safe* to do so.

The answer to that question is "yes". You'll just turn more money into
noise than normal.

Jay, I concur with your statement. Will you agree with this one? "Other
considerations aside, it's safer to not operate near red line."

That was the point I was trying to make, although I can accept I didn't make it
very well.
