27000 to 7000 in 1 minute

I WILL DEFINATELY START CHECKING MY MASK MORE CAREFULLY. gOOD JOB GUYS.

Yeah, its easy for me to sit here on the computer and review this incident, but experience has taught me to "dont let a bad situation get worse". We used to have windshields on the CRJ crack all the time, and I dont recall anyone tearing off the tail.

Had 3 CRJ windows crack in my career all above 27000 feet, one on the fo's side and two captains side. The first one we did an emer decent to 10K and then landed. After that we learned that it is a non event. Just check if the A/C is still pressurized/ing and decend to 25K or lower and continue on.

Of course we always check if the emer o2 was working on first flight.

Actually, you would be incorrect.

Power : Idle
Props : Full forward
Decend : MMO

You will have a 25 degree down deck angle on an emergency decent. If you have never done one in real life or for practice, and you are flying the 200, you need to do it because it is rather hair raising to actually see it for your self.

For the sake of accuracy, I just want to state that no where does Raytheon direct an emergency descent for a cracked windshield. And Turbine was right in that you won't find it in any emegency checklist. It is considered an Abnormality.

And for the sake of more accuracy, it was BB1638, a 1998 model.

aw...ya beat me to it.

there is indeed a checklist, but it is not an Emergency one, it is in the Abnormal Procedures section as mentioned, and its in all models of King Air.

i for one, think everyone is giving these guys too much credit. NOWHERE in the book does it say to DEPRESSURIZE the cabin and come screaming down out of the sky. talk about links in the chain, hell they CREATED the dam chain.

and just for arguments sake...it does not in fact, mention anything about oxygen system or masks, so that argument is for naught...

The only credit I give them, is for ruining a good airplane. It will be interesting to see what the FAA thinks.

EXACTLY...417knots in a dive is what...about 480mph and they wonder what happened to their horizontal stab?

sheesh...

Fully depressurizing the cabin was the big mistake. Once they did that, I think we can all agree that the emergency descent was a good idea. Raising the cabin pressure slowly to take pressure off the windshield is the recommended procedure in most airplanes. Dumping the cabin quickly could actually cause it to implode.

After you shoot yourself in the foot getting medical attention is certainly a good idea.

In typical fashion the media has it completely wrong. They are praising these guys for landing the damaged airplane and have no idea that the damage was really the crew's fault. As has been mentioned here a spidered windshield is not that big of a deal. Happens quite often likely hundreds of times each year. Most crews handle it without totaling the airplane.

 

[Way2Broke]

that is what 330 feet per second?

I'm not so sure they are the ones who actually initiated the decent, they just woke up to stop it. Turns out, pickling the autopilot might have saved them, otherwise they might have been a lot further south, still at FL270.

 

[APFPilot]

Everyone is assuming that what the article is correct, about IMMEDIATELY depressurizing the cabin. That part was not a direct quote and I can see a reporter taking something that they said to that effect out of context.

 

[TXDA2000]

Most likely, since they passed out. If they didn't dump it, they sure tooled around for a long time without O2 thinking of options. If the cabin was anywhere under 20,000 feet they would have remained conscious.
