That seems awfully high. What is the hover ceiling for, say, an OH-58D?

FAA Report




Pilot - Flight Instructor; Commercial; Helicopter




The helicopter was following participants in a downhill skateboard race in mountainous terrain. The pilot had just performed a left-pedal

turn and the helicopter was facing upslope to the mountain. The low rotor warning sounded and the pilot lowered the collective and

increased throttle. The pilot stated that the engine did not respond so he continued to lower the collective and looked for a place to

land. During the forced landing on the downsloping terrain the helicopter came to rest on its nose, resulting in substantial damage to

the main rotor, skid tubes, and tail boom. Post accident examination of the helicopter, engine, and systems, revealed no anomalies. The

density altitude was calculated to be 10,600 feet. The pilot calculated the in-ground-effect hover to be 8,500 feet pressure altitude,

the out-of-ground-effect hover to be 5,000 feet pressure altitude, and estimated the gross weight to be 2,320 pounds.

Remind me not to crash into an idiot festival like that in the video.

Can you imagine being in need of help in a wreckage and all you saw outside was Bill and Ted with their cell phones capturing a "most righteous event"?

"Holy fcuk dude!"

An Out of Ground Effect hover at a Density Altitude of 10,000 feet in a helicopter that looks like the engine might be the same one to power a snow mobile?  I wouldn't even need to do any pre-mission performance planning to know that I would not want to attempt that.

Many pilots don't have enough respect for mountain flying.  Alot of things going on in that type environment, and while not inherently dangerous, it is very unforgiving.

I'm at a truck stop where I can get internet service and have no sound, but I had similar thoughts. I would not want to have an incident anywhere near a bunch of people out of the general population.

Come on.......It's an Lycoming IO-540.  That's the same engine in used in Cessna 210s, Piper Saratogas/Cherokee6s, Beech Bonanzas and Barons, etc.  It's a good engine, it just can't perform at that altitude without a turbocharger......especially at gross weight.

The pilot was an idiot, there was nothing wrong with that helicopter, the engine, or its design.

Having logged a few hours in a helicopter (a UH-1H at that, not exactly an overpowered aircraft) above 12,000 ft (and I mean landing and taking off in unimproved LZs), I was just making an observation about the Robinson and mountain operations.    

I am not sure the Lycoming IO-540 could hold that aircraft in an OGE hover with a turbo charger, but what do I know, my piston rotary time is limited to about 50 hours or so in a TH-55 running around at sea level, so maybe it can.  I have seen the aftermath of an UH-60 after it lost tail rotor efffectivness at 11,000 feet while attempting an OGE hover and the twin turbofan engine performance of that bird (and it's max gross weight) far exceed the Lycoming IO-540 and the Robinson.  Comparing peformance of fixed wing aircraft and rotary wing aircraft sporting the same enigine is of little value anyway.

A Dodge Charger is a nice car, nothing wrong with the engine/performance, but an Indy Car driver doesn't need to do a time trial lap with it to know it will not perform his environment.  That was point I was making more than the value of the Lycoming IO-540.

And you are very correct there with that analogy.  



10,000'+ with a R-44 is not the wisest thing in the world, especially when the pilot did not give himself any outs.  Turning upslope was not a very bright move.  I get to fly at high DA's all the time, but I am in a medium twin, and we don't put ourselves in shitty situations.  




The R-44 is a capable aircraft, within it's envelope.  It's also a very forgiving aircraft, initially.  That's part of why it's actually a dangerous aircraft to fly.  It's very forgiving, so pilots often get used to getting away with things that they shouldn't be doing.  However, once you cross a certain boundry of stupid, it quickly loses it's forgiving nature.  So pilots get complacent, and do things they shouldn't be doing in the first place.  A friend and I had this conversation this last summer.  I had previously instructed in the R-44, and he was a instructor/test pilot at RHC.  We both had the same opinion of the aircraft.

I love R44s....except when it comes time work on that damn engine shroud...If I remember right they're derated quite a bit.  Not exactly a forgiving aircraft when you get behind the power curve.

Just to put my opinion in.......

I have a couple thousand hours of Robinson (22 & 44) time, and a couple thousand hours of B206 (B & L).  For purely the flying end of things........in low level ops, I would take the R44 any day over the 206.  Much better tailrotor & faster.  But getting up high, the turbine is a must.  I've never flown a R66, but I'm sure it would be my choice over the 206.

Robinson messed around with some tubrochargers and diesels, but could never get them to pay off for the extra weight, MX, and money.  They had to bite the bullet and go with a turbine in the R66......but Rolls Royce designed on specifically for that helicopter.

+1.  I don't have much Jetranger time, and not nearly the amount of time in the -44 that you have.  I did love flying the R-44 back when I was flying it.  It was always a pleasure to fly.  And the tailrotor is fantastic.  

 



I had another friend who very early in his career lucked into a corporate gig flying R-44's.  Good pay/benefits, etc.  Never understood his rush to get out of that job and out into the utility world.  Guess the grass is always greener.

Haha. That depends on many factors.

Just stay above ETL.

I would stick with a 206 for the turbine engine alone. Turbine reliability is always higher.

Wasn't talking about reliability, maintenance, hourly cost, parts availability, or anything else......just the stick.

But since you brought up reliability, I disagree.  When a piston engine is failing, it starts running rough, temps go up, pressures go down, etc.......you may get a few minutes out of it to find a spot.  Lots more moving parts inside of a piston to break though.  But when a turbine engine quits, it just quits.  Ice, birds, tiny air leaks, etc can all wreak havoc on a turbine and cause it to quit.

I'm not saying a piston is more reliable, but it's not less.  And I would rather have a piston failure than a turbine failure.  For over extended over water ops, I would take a turbine.  But over forests, I would want a piston since I might be able to limp it into a clearing.

Both engines are very reliable if maintained correctly.

How can you not like the starting sequence of the 206?

Its aurally stimulating and fun


I'd like to punch the bell engineer in the face. I hate the horn. One in the 206 is annoying. 5 in the 407 makes me want to shake a baby Every. Single. Time.

Eurocopter did it right with the button to activate the horn

You're welcome to that piston engined helicopter.   I don't have to pay the operating bills so I don't want one ever again, under any operational circumstances.

Well, somebody didn't think about TOLD.
He's dang lucky that he had that pleasant of a crash, if you ask me.

It also appears that the cameraman in the first video was enjoying the benefits of Colorado's laws regarding things to be smoked!
