JetBlue Hydraulic Failure at LAS

3.5 hours of circling? Sounds like it was a pretty serious incident. I looked at the Flight Aware data and that thing was all over the place. Kudos to the crew.

I see a few really pointy parts of that flight path... Either Flightaware's data is jacked, or those were very fun maneuvers.

"mechanical screeching" = PTUs?

I'd call that more rubbery grinding/squeaking, I don't know why someone would describe that sound as a screech, but its possible I guess.

I call it feisty dogs barking in the cargo hold.

I like to be creative if people next to me ask if I know what it is, told a lady it was a midget humping the luggage once. I've heard a lot of flight attendants call it the "barking dog".

Kudos to JetBlue though, they needed some positive PR for flight crew professionalism after the recent "incident".

Is it more dangerous to fly around for 3.5 hours with only one hydraulic system, or to land overweight? Based on my extensive Cessna 172 experience I think I would rather land.

Truth. I hate it when two of the three hydraulic systems go out in my 172.

Don't each of the brakes have their own? And... um... I guess I could count the hydraulic system that belongs to the PIC. When that fails, I guarandamnTEE that I'm putting down ASAP.

Guess when you have three computers doing the flying for you its not too bad...

That's what the Pause button is for.

audio incase anyone is interested!

I wasn't there, but a few things here don't add up.......

Sounds like you could also be referring to several Boeing products...

Same in the A319/A320/A321

Interesting...I'm curious to hear more about this.

First, I am going to say I wasn't there AND the Hydraulic and Electrical Failures/Problems are the hardest to properly troubleshoot on the Airbus (see UAL in MSY earlier this year)

Secondly, here is why it doesn't add up...

-If there is a failure of BOTH Green and Yellow Systems, then the Flaps, Slats, Thrust Reversers then yes you are in a world of hurt. We did that in the SIM going into SKBO (Bogata) and myself and my sim partner ran off the end of the runway as well as 99.99999% of the trainees. However, that was in an airfield of 8000+ feet. I betchya if you ran the numbers for say an airport such as LAS, a dual hydraulic failure you would have a comfortable enough margin to land rather than risk a third failure of the Blue System (which would have been REALLY bad). Even if LAS wouldn't have worked, I betcha LAX would have...

.... with that....

-If I read the article correctly, they did restore one system. With the PTU a restoration of one system would power the other system so everything SHOULD have been working ok. If your flaps, spoilers, brakes, reversers are working OK, then an overweight landing isn't a big deal as...

-We have a procedure to do an overweight landing. During training at my place the instructors and check airman were adament that it is not a big deal to land overweight rather than risk more issues compounding in the air. The airplane is so automated the mechanics can very easily tell if any stresses were encountered during the landing and can be a very quick sign off. I have less than 100 hours in the plane, but the Captains I have flown with everytime have included in the briefings that if we need to land overweight we will rather than risk the problem compounding itself. If your plane is broken anyway, get it on the ground ASAP to get it fixed rather than worry about an additional inspection!

Maybe @Cruise and @PeanuckleCRJ can correct me if I am wrong on the info, I am new to the plane, but as I said somethings here don't add up.

Wow, failure of two hydro systems at once. Crazy. Sounds likw a real PITA that those guys worked out well.
