For heaven's sake, just check thoroughly that the aircraft is fit to fly before flying it.
The for heavens sake method clearly doesn't work when it comes to V2500 engine cowls. So, we need to look at other ways to solve this problem.
The for heavens sake method should also be applied throughtout aviation, but for some odd reason it doesn't work all the time. Even if it is in the OM-A.
That's why we have (E)GPWS, TCAS, stall warnings, overspeed warnings, and a number of other defensive measures installed.
We are just not perfect enough.
