So far it seems that Ppruners know of not a single actual hydraulic failure on a 350, yet know of many incidents and some fatalities practicing for the eventuality. Surely there must be knowledge of many actual failures amongst the huge collective experience here? Any offers again?

I know of 3 seperate cases of belts breaking that drive the HYD pump.
This was before the new style belts come on the scene.
All were a nonevent with the machines landing without incident and the spare belt that was already sitting over shaft being installed and the machine carried on back to work.
If the accumulators are charged properly and the pilot has adequate knowledge and training a HYD failure should be a non event.

I’ve had a hydraulic failure in a B2, (also in a JetBox) was a bit scary at the time, but landed without to much headache. Was light at the time around 1,850kg. It’s not a serious event if properly trained for :hmm:

AS 350 , 1400 kgs+ empty, 900 kg internal load, an hours fuel plus pilot. How do you reckon you'd go with a hydraulic failure? That's a good reason for sticking to MAUW , I reckon I'd struggle, my boss thought it acceptable.

Hey Skidbiter4eva..............2,524kg Yikes that's scary. Remember if You bend it over 2,250kg (unless dual-hyd; 2,370) You'll wear the bowl of soup on yer head & be in the can, Man :ugh:

Yep hydraulic failure at that weight would be F.F.F.Fvkin' frightening, probably just about unmanageable unless Your Superman :mad:

Would be strange if nowone did’nt know about any AS350 accidents related to hyd failure! I didnt fly the type, but I still know about ”some”.
I know there was a thread here soemyears ago about the subject.

I wont be the one putting a list of such accidents here, but it would be quite easy to do.

It's why I'm no longer there, thanks for your opinion, although it was a financial disaster for me to have to move, I know it was the right choice.
