Bell 206: JetRanger and LongRanger

[levo]

Hi all i am in the market for a jetranger around 200k must be bell not agusta and have c20b engine e me if you know of any yes i have checked most sites but there might be a few owners thinking of selling

thanks Levo.

Should be a few more on the market once the r66 is in full swing

Should be a few more on the market once the r66 is in full swing

D'ya think so? Personally I bought a JR as I just didn't want an R44, I can't imagine that many jetbox owners will be interested in the R66.

I would imagine that most 'incomers' to the R66 will come from R44's rather than 206's.

[toptobottom]

206 Jock - agreed. The R66 might be a cheap turbine, but IMO it's still a lot of money for a cramped and ugly 5 seater. Instead of $750k for a new R66 I'd much rather look at a good used EC120. Or if my budget was $350k, an R44 or jetbox.

If only Frank had hired a capable styling designer all those years ago I'm sure we could have had economy with just a smidgen of style. Alas it was not to be!

All should not be woe, after all there is a new Robinson starter on the blocks, seen here at pprune, a more reliable newshound than the Daily Tele at the corner shop.
It did look a bit chunky at it's last showing, but and alas the Marquis Battista is no longer with us I lament, however his successors seem more than up to the task to fulfil your suggestion as above.

And is this new creature to which you refer by any chance the elusive "Reightyeight?"

Yes, and highly reighted down under.

A quick few questions:
- magnetic compass is positioned rather strangely on BIII's I fly, on the right side , knee height, just in front of right front door. Is this common place, and if it is, why? Why not in front, in the middle? Some bad interference?
- what's the story behind two TOT peaks during startup (C20B)? Why are there two, what influences on their values and time saparations?

Thanks

It's a standby compass, (so you're not expected to use it as a primary reference for direction!) that's why its location.

Two peaks on TOT during start up are for the initial fuel introduction (to ensure thngs don't get too hot with the limited amount of air flowing through the turbine section.) And then an introduction of more fuel as an acceleration up to self-sustaing at 58% N1 and then on to your stabilised idle of 64+ or- 2% ( I think). Again so you don't have stagnation and a long hot soak whilst the airflow builds up. Lots of thermodynamic bad issues with that, manifest themselves further down the line.

As a by-product of all this Allison (sorry chaps, showing my age ) R-R recommend hot(er) and fast(er) starts

There you go, have a good one ~ VFR

Drivel alert!

It's a standby compass, (so you're not expected to use it as a primary reference for direction!) that's why its location.

Really? So where is the "main" compass?

Have a sniff around a JR and work out where the battery cables are! Then you might agree it's the best place to locate the compass.

2 peaks on start?

You could say the two peaks or one trough. It is to avoid surge/stall at a certain speed. Accommodated by the start notch valve in the FCU and subsequent adjustment to the Wf/Pc ratio.

[Gomer Pylot]

I think the compass location is a combination of maintaining distance from the battery and the taxi/landing lights, and space. There is no good place on the glareshield, and on the right is an empty space visible to the pilot.

The two peaks are there because that's the way the Allison engineers designed it. It would be more convenient for the pilot if the temp came up slowly to a point in the green and just stayed there, but no part of the 206 was designed for the convenience of the pilot. It is what it is, so accept it.

[FH1100 Pilot]

Accommodated by the start notch valve in the FCU and subsequent adjustment to the Wf/Pc ratio.

Well that surely explains it clearly! Uhh...I think...

Actually, I prefer Gomer Pylot's take: It is what it is.

[Gordy]

All you ever wanted to know about Allison starts but were too afraid to ask:

SEE HERE---you're welcome

[handbag]

Gordy, I was told that an upgrade in the FCU bellows has invalidated that letter?

G'day to All

Re'f BELL 206 performance computer and cruise data guide

I know a wizz weel computer exist for the OH-58A kiowa.

Wonder if we have a equivalent for the civil 206b,b2,b3,l,l1,l3,l4.

A pilot got en g chip light flying a Jetranger and landed on a field. The technician that was with him took out the chip and found a "hair like chip" on the detector. After second start-up there was some blue smoke from the exhaust.

Despite that and the fact the helicopter was 2 hours from major maintenance, a TRI decided to fly the helicopter back to base some 20 miles over hilly and wooded terrain.

My thoughts; I would let the helicopter come to base by truck.


What do you think? Anything similar happened and can be found in some "final report"?

[Chris P Bacon]

Hair like debris is normally pick up from one of the labyrinth seals. nothing unusual if the engine is just out of repair.
After the first chip light, I would always advise a 30 minute ground run taking the aircraft light on skids. If no further warning, you should be good to go.
Keep the debris and have it analysed. A good M250 facility will do this for you and let you know if it is bearing or gear material (even potentially which bearing or gear)

[Phoinix]

The engine is roughly 1000 hrs since overhauled.

I would say there was 5-10' ground run before the flight back.

[Helinut]

In general, the engine manufacturer has a specified maintenance procedure for action following an engine chip. In the absence of something else, follow that procedure. Not sure what RR specify for the Jetbox.
