What is the worst condition for the cabin pressure vessel in TBM900? Can it fail completely?

Recommended Posts

Greetings. This is just a "curiosity" post really.

So I've been messing around with the TBM900, trying to see just how badly I can wear it out if I'm super sloppy with everything (but not to the point of crashing). After a couple of tail strikes with repairs, the cabin pressure vessel has degraded to a "deathtrap" condition (which got a chuckle out of me ;)), but I'm too bored to do even more tailstrikes to see where it gets next.

So:

  • seeing as the pressure vessel becomes "worn" or "very worn" after just one repair, skipping the "good" condition completely, what exactly happens when the pressure vessel degrades?
  • what is the worst possible condition? Can it break completely (become irreparable)?

The cabin won't pressurize, as indicated on the MFD, and you'll get hypoxia at higher altitudes.  The screen will slowly turn black.

Hmm, so I flew with this cabin in "deathtrap" condition up to 30000 ft, and it did pressurize okay. Is it going to slowly leak air or something?

It could definitely go at any time.  Once it does, you'll need to use the oxygen mask, and once on the ground, you'll need to create a new airframe.
