Ok, sounds like all the warnings inside Army vehicles with the "Crew required to wear double hearing protection during operation" Ill give you three guesses as to how often that happens.
It is not even close to being the same.

Think about it. Two countries build airplanes but each has no idea if the other countries airplanes are safe to have over the heads of their citizens.

So how do they visit each other?

In 1919, many countries sat down and answered that question. They decided that the only way to ensure everybody else's aircraft were safe to fly over the heads of their citizens, was to agree to meet the same standards and principles.

They agreed on navigation, charts, landing procedures, and other things about how airplanes are built and operated.

One of the major things was the standards of airworthiness. Why are the operating limitations part of the airworthiness? That is what the manufacturer has certified the airplane will fly at within the very narrow engineering safety margins that are required to achieve flight. The airplane is only reasonably guarentee'd to work when operated within those published limits. It is airworthy airplane only within those operating limits.

Once again, the engineering safety margins are just too small. What does that mean? It means an airplane is not overbuilt. It is built to exactly what it needs and nothing more. When it says in an operating manual something is a limit, it is real honest to god limit. Push an airplane past what is written in the Operating Limitations is a great way to die in reality. A fighter, like any airplane by design operating limits is already operating on the ragged edge of disaster. There just isn't any wiggle room. Sure you might hear a few cool stories about guys how did it and got lucky. You won't hear the stories of the guys who did it and were not so lucky. Not adhereing to the published operating limits in an airplane is a really, really, stupid thing to do. It is playing Russian roulette and hoping the outcome is good.

In fact, the FAA determined that deviating from operating instructions is a factor in 85% of the accidents in aviation. What does that mean? It means if you disregard the operating limitations in an aircraft, the chances are extremely high it will come back to haunt you.

That leaves us with a total of two situations where the power plant itself failed - in 4.5 million flight hours. Both situations are suspected to have been the result of the aircraft being operated outside of the engine limitations

Now, how does a country ensure that the people that make and fly airplanes are abiding by this agreement among nations and at the same time ensure their own nations aircraft are airworthy? They make adhereing to the documentation governing aircraft airworthiness have the weight of law and they enforce it. It is common sense too. You just are going to win a war if your airplanes don't fly.
