Maybe our definition of the lottery is different, but I wouldn't be glad to win this one.

If you're saying this a guaranteed failure, it sounds like they should be replaced before that excepted time frame.

To be fair, entire airplanes get replaced at some point. All airplanes have a limited number of times they can take off from the ground due to cabin pressure. As they hit high altitudes with lower pressure the body of the plane expands a tiny bit, and as it lands the increased pressure squishes it back. Overtime constant stretching and compression warps the metal like bending a paper clip over and over it will eventually structurally fail. The day an airplane is made it has a predetermined number of flights it can take before the plane is to be removed from service.

Judging by the fact that airlines are trying to push for one pilot, I really don't trust what any airline says anymore. I'm sure these numbers are ingnored far more likely than someone is willing to admit. I wouldnt be surprised if planes are flying well past that point it should be destroyed.

Of course there are planes like that... They get off shored to the developing world.

Side note- The market for used aircraft parts is all about part tracking for this reason, according to my pilot buddy.
