Key Takeaways:

The article advocates for Lean of Peak (LOP) EGT as an effective engine cooling method (cooling with air), emphasizing the need for well-balanced mixture distribution and proper pilot understanding.
It discusses the debate between the terms "crash" and "accident," noting their differing connotations regarding blame, preventability, and historical use in transportation.
While *Aviation Safety* adheres to the NTSB's specific definition of "aircraft accident," the editor views the distinction between the terms as largely semantic, stressing the ultimate goal of reducing such events.

Having long been a lean of peak (LOP) exhaust gas temperature (EGT) advocate (25 years), I think some further explanation to Andrew Strauss and some of your other readers about that form of mixture control might be in order (Unicom, August 2024).

First of all, not everyone has mixture distribution that is well balanced enough between all their engine’s cylinders to run lean of peak with smooth engine operation. If they do, then it should definitely help.
