Shame they would not let you have a closer look at the B429 on the stand unless you had a secret handshake or what not, it's not my fault I could only go on the Sunday.

Troglodita 23rd July 2008 03:30

Any truth in the rumour?
 
Is it true that Bell are renaming the variant for the Nigerian market the Bell 419?

Just provide your bank account details and send a small deposit and we guarantee that you will be at the top of our delivery list! ;)

429 for Bond? ref Franborough
 
At Farnborough last week, had a chat with the Bell reps and found out something interesting that Peter Bond would be visiting the Bell chalet and that BAS had an interest in the 429. So there may be a possibility that BAS may go away from the traditional purchase of Eurocopter models??

And also the engineers said that the 429 easily beat the EC-135 in terms of performance especially at hot and higher altitudes

Aser 23rd July 2008 09:56

First time I see a conventional tail rotor with so much protection. :ok:

Squat switch 29th July 2008 16:39

Those skids look a tad on the thin side!? :uhoh:

"And also the engineers said that the 429 easily beat the EC-135 in terms of performance especially at hot and higher altitudes"

What engineers, Bell engineers?:rolleyes:

SASless 29th July 2008 20:32

Just proves how you can tweak, stretch, morph, and digitally twist the grand ol' 206.

One of these days the Bell designers will be issued a blank piece of drafting paper....given cart blanche....and who knows what will come out of the new found freedom!

Of course they will have to retire a heap of folks to get down to the point they can hire young un's that have not become slavish Monk's busily copying the one set of drawings.

Perhaps they will one day think outside the box....Jet Box that is!

Encyclo 29th July 2008 21:30

Not too many 206 part numbers on this one SASless. Pretty well clean sheet design from what I have seen.

I guess you're right; with only 330 sold so far Bell should try and do better next time :ugh:

Shawn Coyle 29th July 2008 21:46

I'll go out on a limb here and defend Bell. Each manufacturer has a 'trademark' look. All cars do this. And so do most aircraft companies.
When you have a number of conflicting design requirements, and a given level of technology you're going to produce something that looks a certain way. Engineers try to be inventive about solving the problems, but everything becomes a compromise.
There's a good reason that all small cars look pretty close to the same. Can you tell a Honda from a Toyota when both are presented in profile at 100 yards? Good reason why they look close to the same. Both companies have the same design aim and the same technologies in metals and engines.
I think you'll see very little that's close to an original Bell 206 when you look very closely. A lot of time (and I mean a lot of time) went into this design.
I just wish they'd get it out and into production.

SASless 30th July 2008 00:24

Well I guess it saves on wind tunnel hours if they all have the same shape.

The 412 even has 47 part number parts on it...with 204 part numbers too.

rotorrookie 30th July 2008 01:55

WTF is it with this cockpit seats???
Was The Hunchback from Notre Dame in the design group or what:confused:
Has anyone here had the pleasure to stick his butt in them?

And how is the forward visbility from cockpit compaired EC-135 and MD-900?
Looks like a preatty big dash to me according to the photo

estepo 30th July 2008 09:32

Any idea where I can get hold of one of the elaborate hairpieces the guy's got in the last photo?

I've checked the News of the World colour supplement, and I can't find a thing. :E

chopper2004 30th July 2008 10:17

rotorrookie

I sat my behind in the cockpit and felt quite comfortable, a lot more room than the 902 (also 110% more than the Robinson 44 which I fly anyhow but thats another story!!:cool:). Also there is a good height clearance even for a 6ft jockey (I'm 5"7 anyhow so that doesnt really count)

Admittedly forward view isn't too bad, with the EC-135 and MD902, there is more at feet level but still was the 429...its good at knee level.

Plus seats go back and forth on a rail (unlike the Robbo 44 :D)

Certification
 
Bell 429 Achieves Certification
FORT WORTH, TX (July 1, 2009) – Bell Helicopter, a Textron Inc. (NYSE: TXT) company, today announced the certification by Transport Canada Civil Aviation (TCCA) of its newest light twin engine helicopter, the 429. Bell has also completed the Federal Aviation Administration (FAA) certification requirements. First deliveries are scheduled to begin this month.

alpineflyers 4th July 2009 11:21

I have actually flown the 429 2 weeks ago in France. Best performance I have ever experienced at 14000 feet (Mont Blanc), hovering OGE with a MTOW minus 700 lbs. There are virtually no vibrations at any speed. Extremely nice handling characteristics, much better than E........... Should be a winner.

Shawn Coyle 4th July 2009 14:00

Sir Shawn??? Pleease!
I did enjoy flying the machine, and trust that comes across in the article. Several things that will be very noteworthy in the long run - the use of the Maintenance Steering Group 3 (MSG 3) in developing the continuing airworthiness of the machine will mean much better maintenance - it's already at 200 hours between inspections, which must be a first in helicopters. The thought given to the cabin layout and other parts of the fuselage will mean that the ever-present modifications will be easier and cheaper to get approved.
The performance and smoothness are outstanding - and the easy upgrade to a 4 axis autopilot means that Bell was really thinking about this.
It is the first new design from Bell since 1979, and the engineers really listened to the pilots - which was very nice to see.
And I guess I should get a commission on future sales...

alouette 4th July 2009 14:18

The Bell 429 "should be a winner"?!? Finally Bell dumped this damn butterknife shaped blade design. I hope it's a winner!!!:ok:

Spunk 8th July 2009 13:50

Bell 429
 
:ok:Being a happy 407 driver I wish Bell all the best with the 429 programm. Are there any performance charts available yet? :ok:

alpineflyers 8th July 2009 22:52

The charts have not been made public yet. I have seen them and worked out some weights - impressive. Plus they do work in reality, something rare.

helisteve 9th July 2009 01:12

Has the MAUW been increased?

Shawn Coyle 9th July 2009 12:13

Currently max weight internal is 7,000 lbs, and not likely to go beyond that due to certification limits (that's a much as a Part 27 machine can weigh with an internal load).
External max weight is 7,500 pounds, but the additional weight has to be jettisonable.

Shawn Coyle 13th July 2009 12:01

Just a comment about parts and using parts from older machines.
It's quite common to use parts already approved on another machine as they don't need to undergo an extensive (read $$$) approval process. The company also doesn't need to put in another part number into their supply system. There's less chance of screwing up and getting the wrong part number, and so on.
I remember being slightly shocked when I started work at Bell in 1984 on the model 400 (anyone remember that?) to find out it actually had Bell 47 part numbers. But I quickly understood why.
In the 429, Bell did use a 'clean sheet of paper' approach, and only used older model part numbers where appropriate. It is a new design.

widgeon 13th July 2009 22:11

I recall S58 parts in the S61 and some gazelle part in the AS350/355.
wonder as the Blackhawk was entirely funded by US goverment if Sikorsky used many existing parts

MightyGem 14th July 2009 02:07


it's already at 200 hours between inspections, which must be a first in helicopters.
Afraid not. The EC 135 has been at 400 hours between inspections for a couple of years now.

Shawn Coyle 14th July 2009 02:26

Mighty Gem:
Thanks.
I stand corrected.

handbag 14th July 2009 03:04

How significantly do those staggered tail rotor blades reduce the noise signature?

Shawn Coyle 14th July 2009 13:28

Handbag:
I don't have any definitive numbers, but listening to one of the prototypes fly overhead, it was significantly quieter than other Bell models.

handysnaks 14th July 2009 17:54


Afraid not. The EC 135 has been at 400 hours between inspections for a couple of years now.
Which we all know is a bit false MG as there are a quite a few supplementary inspections that occur every 100 hours or so:cool:

Bell 429 user experience
 
Any folks able to report real-world experience yet?

widgeon 29th January 2010 10:30

Bell 429 , any news
 
The ref to the 429 in the rega thread made me think.

The last serial number noted on TC web site is 57008 , this is now registered in USA along with 57006. I thought they had certification and a full order book.
8 aircraft in 3 years is kinda slow.Any one know what is holding up deliveries.

21stCen 30th January 2010 05:42

An article in Aviaiton International News (AIN) on 01 October 2009 showed the following forecast production rates:

The 429 production schedule remains at 40 planned for delivery next year, 80 in 2011 and 96 (representing full-rate production) in 2012.
Also in that same AIN article:

At the time of certification, Bell reported letters of intent (LOIs) for 301 aircraft. It is still in the process of converting these LOIs to purchase agreements, so it is not announcing converted firm orders yet. Holders of LOIs had until mid-September to confirm their orders, but the conversion process takes longer, because after the deadline, Bell marketers go back to buyers who cancelled their late-delivery aircraft and offer them earlier delivery slots. “We need to know the true conversions and slots available,” said Marshall.

Bell typically gets a 95-percent conversion rate for letters of intent, he said, although the current state of economies around the world could harm this rate.
Has Bell announced the number of converted firm orders still held? (it's been four months since the above article was released)

Ian Corrigible 30th January 2010 14:19

As of late October the converted LOI total stood at 50 aircraft. The 429's production rate has been trimmed back to 25 aircraft this year and 40-50 in 2011.

I/C

21stCen 30th January 2010 15:34

Thanks I/C,
Stunning -- out of 301 LOIs only 50 orders remain!? Has there been an official announcement from Bell (couldn't find that on an internet search)?
21stC

9Aplus 30th January 2010 20:09

I like to buy some, on US company conditions and on claimed 5M USD price....
Any offers please? :E

Ian Corrigible 31st January 2010 20:25

21stC - not yet, but the numbers are legit.

I/C

TwoStep 1st February 2010 22:18

Bell say they are working on converting another 50 LoIs on top of the 50 that Ian Corrigible mentions. It's a slow start, but if they keep the faith...:}

GeorgeMandes 2nd February 2010 02:15

Looking at the economy over the last 18 months, and the cancellations and deferrals of every aviation manufacturer that I have seen numbers on, I suspect the shrinking of the order book has little to do with the 429, and a lot to do with the financial issues faced by the 429's customers.

While I personally wouldn't be thrilled with owning one of the first 50 serial numbers of any new helicopter or turbojet, I have a buddy with a bunch of time in the 429 and he says it is an incredible performer -- as in 4,000 fpm climb.
