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

[Walter Atkinson]

Kyle:

The study was done by American Airlines and the result was a TBO extension from 800 hours to 3600 hours, by doing nothing more than stopping running the engines ROP and making sure they were all run LOP. The data was so compelling that Wright Aircraft requested the use of the data to compile, publish, and distribute a booklet on engine management entitled, "Basic Theory of Operation of the Turbo-compound Engine." It was given to every flight engineer and the methods were followed to the letter. It became known as the WAD Manual (Wright Aeronautical Division) and can be purchased from Fly Bye Knight Press.

It is an eye-openning, informative read.
