Bell 206: JetRanger and LongRanger
Longranger LR = C20R +7% ??
Hi all,
Recently got to play in a Longranger LR model. Giddyup.
Had a discussion with a bloke that confused me and left me a little bit skeptical.
Apparently a C20R engine fitted to the LR is automatically given a +7% addition to its power assurance check. This was introduced during a discussion about the additional weight that can be calculated in the FM while working out your HOGE weights.
IE: if you are landing at 5000ft you might be able to carry 3500lbs of MAUW. Should you be flying the LR model, at that temperature and height you might add another 250lb of weight as per the FM chart.... no problem.
However, the reason for this is supposed to be that the C20R model is given a +7% rating to the PAC.
I find no mention of this in the FM and wonder if it is just more "Rotor Legend".

The only longranger with water injection was the original with the C20B engine.
I seem to recall that it was not standard kit. Perhaps someone has a copy of the RFM supplement.
I have heard that there were 206A's with the C18 that had it too but never saw one.
Bye the way - yes someone once actually did grab the wrong jerry can and fill the resevoir with jetB.
Upon injection the torque available was considerable - the TOT did however exeed all limits. It actually expanded the burner can and turned the outside of the turbine section a pretty purple colour! What it did to the burner can, nozzle and turbine wheels was impressive.

Pah site sucks and took ages to login but .... What oil do you use in your engines, if it is not Mobil 254 or equivalent generation with high temperature qualities then this is normal & you will end up reducing the HMI time of your turbine. If you are using Mobil 254 then send me an email.

Long Ranger Spray Gear
Hi Fellow Ppruner's,
Hope there is someone out in our big wide helicopter world that might be able to help us.
We are looking for Sprag Equipment to fit a Bell 206 Long Ranger.
Used if possible.
Regards
Bell 206
Many happy landings to you all!

Someone a bit closer to home is South West Helicopters at Cootamundra. They operate a spray 206. Terry McKenzie is the owner from memory.

JetRanger
Can someone explain to me the difference between Jetranger II and III. Was there a "I" too? I would like to know more about it's history of development. Some www site where this data is available (google didn't bring much), or your pure experience. Thanks!

And bigger Engine on the three. you also have the difference between the A model and B model.
I only remember that the III has a 420shp and maybe the II only 400shp and the I was 380shp don't quote me on that though. Someone will surely come along soon and give all the right in's and out's otherwise have your tried Heli Links ?

The 206A had an Allison 250 C-18A with maximum output of 317 shp. The "B" had an Allison 250 C-20 with 420 shp. However, I believe the maximum take off power of the C-20 in the "B" was limited to 317 shp, the same as the "A" model. These are the main differences, as I recall. I'm sure there's someone out there who can fill you in on the others.
