Engine Analyzer Question/Lean vs Rich of Peak/Engine Longevity

[gwbraly]

Ernie,

IF you do a careful Failure Effects Modes Analysis, one of the FAA's favorite activities, one normally comes to the conclusion that the person operating an engine on the rich side of peak EGT needs an engine monitor to protect against a more serious and potentially fatal set of engine failure modes - - than does the person operating with the mixture set lean of peak.
