How long should I go on engines?

[Ernie Martin]

Skyking:

I think you misread my message. My main point is, and I quote, that you should "fly it as long as all parameters look good". Let Part 135 operators worry about the 1500 hours. I then went on to say that I don't know what the failure distribution looks like. The sole purpose of the graph was to show that more frequent failures may start appearing at 1500 hours, but that for most engines there are still lots of hours left -- absent, of course, poor maintenence and infant mortality (see Kim Geyer's examples in his message on the thread entitled "IO360 - Factory new vs Factory rebuilt" and Chachi's example above).

In short, I agree with you and Chachi: keep a good engine running.
