Bell 206
Looking to buy a 206 involved in a " substantial accident " in 1984.....properly fixed then. Mistake? Walk away? Appreciate any views.....
|
need a few more details really ( is it RNBW )
|
Depends, how properly fixed it is and how many hrs flown since then.
Know one aircraft, where „more or less“ only the typeplate survived - and was rebuild around that, cause some advantages in registration made it worth and cheaper than buying new (with big stock of spareparts available in the company anyway and the mechanics would be busy, when normal maintance were done...) You should have a close look what was damaged and what was replaced. Best take somebody from the Future maintanance facility with you to check the bird and the papers before placing a bid |
If it's gone 33 years since the accident, it doesn't seem like much of a problem.
|
Be careful especially if moving to a new easa maintenance organisation.
History and component record checks are now very very detailed even to the point of draconian. |
Keep clear of Agusta Bell machines.

Keep clear of Agusta Bell machines. Please tell us why? |
I think in EASA land all parts that go on an AB have to come with Agusta paperwork, a Bell part isn't good enough... It hasn't hit us down here yet.
So your Agusta agent goes to Bell buys the part, writes up an Agusta 8130, or Form 1 or whatever its called, adds 50% to the price and sells it to you... |

The UK CAA has helpfully provided some specific guidance on the AB 206 and eligibility of parts to be installed on this EASA Type Certificated product, https://www.caa.co.uk/Commercial-ind...dioncollapse-2. The applicable reference from the former AW is, https://www.caa.co.uk/uploadedFiles/...-004%20(2).pdf. I think you will find that any AB 206 registered in NZ that is operating with any Bell part installed, is no longer in compliance with its Type Certification. The advice of JTobias is very sound. As far as repaired aircraft go. Check carefully who originally repaired it, including the detail of repair information on the records, and then review the history of airframe repairs since that time. A properly repaired airframe is probably in better shape than the original that was mass produced in a production factory. As helonorth has pointed out, after 33 years, its probably proven itself to be good, and its probably had at least one new belly and roof since then. If you have specific questions about repairs, post them here, there's a lot of real expertise on this site. |
Drop a pm to formerlongbox, he knows every 206 in the UK.
|
He also knows how to break many laws so I'd steer well clear.....

Who knows how to break laws? JJ |
Hope this helps clarify the situation:
This is the UK CAAs latest official statement from their website, I see no wriggle room on the subject, could be expensive for some owners.................. I have been informed that one UK maintenance company is carrying out very detailed checks on every Bell or Agusta Bell helicopter being brought in for maintenance. Before you invest in any Bell or Agusta Bell 206 in the UK, I would make sure you have a full (insured) survey carried out. https://www.caa.co.uk/Commercial-ind...6-helicopters/ The text reads: Eligibility of parts for Agusta Bell and Bell 206 helicopters The product manufacturers, supported by EASA, have on several occasions attempted to make clear that only parts that are manufactured under control of the Type Certificate Holder (TCH) or Supplementary Type Certificate Holders (STC) control are eligible for installation on their respective helicopters. Where a part does not meet these criteria, then it should be replaced with a part conforming with the TCH or STC holders requirements. This policy is supported by Information Letters issued by the Type Certificate holders for both aircraft types, clarifying their individual positions concerning the eligibility requirements for replacement parts. Agusta Westland Information Letter (15 November 2006) Bell Helicopters Information Letter No. GEN-99-65 (15 January 1999, revised 2 June 2006) Parts manufactured by or for Bell under their production approvals are not normally eligible for installation on Agusta/Bell manufactured helicopters. Parts produced by or for Agusta are not eligible for installation on a Bell manufactured helicopter. Original Bell Helicopters parts may only be installed on the Agusta Bell 206 when the part is supplied and authorised by Agusta, now Leonardo S.p.A. Authorisation may be provided by Leonardo S.p.A through their EASA design organisation approval. |
This is interesting. Setting aside paperwork and compliance issues for a moment, is there any practical reason why a Bell part on an AB machine is less worthy than the matching AB part, or vice versa?

The biggest curve ball to throw at the whole compliance thing, is that the CR&O to be used for the AB206 series is the BHT206CR&O, as stated in the AB206 TCDS. Nowhere in the BHT manuals does it say to use AB parts. It states that you shall use Bell parts, so you must overhaul, for example, the TR hub and blade assembly iaw BHT manuals with brand new Bell parts as required, but then cannot stick the Assembly onto your helicopter because you didn't buy the parts from Agusta. If you buy the parts from Agusta, then you cannot use them to O/H iaw the BHT manual, as Bell say to use BELL parts, NOT Agusta parts..... Thats why the NZCAA have taken the common sense approach, and don't penalise people for using Bell parts on an AB. |

There are also 300's and 500's built under licence still operating. The one thing that you need to look out for, is the dash number of the relevant assemblies that are being used. sometimes the Agusta got stuck with an old assembly number if the manuals weren't getting updated as fast as the bell manuals. |
Reverting to my earlier response on this topic, all the pertinent documentation and data is included in the various publications.
Specifically: The basis of approval for operation in New Zealand is contained within this document. https://www.caa.govt.nz/aircraft/Typ...SpA_AB206B.pdf The basis for acceptance and issuance of this document is the EASA TCDS EASA.R.140. https://www.easa.europa.eu/system/fi...06_Issue03.pdf Within the NZ Type Acceptance Report (linked above) the following conditions are specified: 4. NZCAR §21.43 Data Requirements (2) Airworthiness design requirements: (v) Airworthiness Limitations: AB206A/B-Series-MPM Maintenance Planning Manual (See SL AB206-04-001) (6) Operating Data for Aircraft and Engine: (i) Maintenance Manual: AB206A/B-Series-MM Maintenance Manual (ii) Current service Information: AB206 Information Letters AB206 Bollettino Tecnico (iii) Illustrated Parts Catalogue: AB206A/B-Series-IPC Illustrated Parts Catalogue Note: See Information Letter AB206-06-004 Interchangeability of Agusta Bell and Bell Helicopter Parts. This states that “Original Bell Helicopter components are therefore applicable to Agusta-Bell products when supplied or authorised by Agusta only.” (7) Agreement from manufacturer to supply updates of data in (5), and (6): CAA 2171 from Mr F Brusatori, Technical Publications Manager, dated 17.03.97 Access to publications is now provided at www.myfleet.agustawestland.com This Note contained within the Type Approval Report requires compliance with the requirements specificed in Information Letter AB206-06-004 https://www.caa.co.uk/uploadedFiles/...-004%20(2).pdf Thus the requirements of this letter are specifically incorporated into the Airworthiness requirements and limitations of any AB206 on the NZ register. There is provision within the IL to allow for differing policy based upon the authority having jurisdiction over the helicopter, but this would have to be specifically approved and issued, and in the case of NZ certification does not exist, because the Type Approval Report specifically requires compliance with this requirement. In response to Krypton John, the answer should be no, there is no difference if the configuration may be identical - this is what went on for years The issues lie entirely in the certification basis and approvals for the parts. Bell have also issued specific guidance on this matter. https://www.caa.co.uk/uploadedFiles/...0GEN-99-65.pdf |
A few years ago I was involved with a company that rebuilt 206s after accidents. They rebuilt about a dozen or so. The work was fully supported by Bell, slow, deliberate and top-notch and all were tailored to the buyer's wants and finished with a bespoke paint job. The biggest 'issue' during construction was bogus parts that were reported as required.
Periodically, they were inspected by the CAA who had no problems with the work done or anything else for that matter. I can't remember any findings (so probably ought to look in my files) The Chief Engineer was also the test pilot - and he was very particular about things within the company too. So, in my humble opinion, there should be no problem in buying a structurally repaired 206 but you should still get it checked out by an independent qualified, experienced and competent person. |
thats good info cyclic hotline, obviously you have done more investigation on it than i have.
problem i see, is how do you overhaul parts when required to do it iaw the Bell manuals?? as a clever auditor will tell you that once the bell part goes to Agusta it is no longer a bell part... and round and round in circles you go! believe me i have been there when trying to comply with 2 different things that contradict themselves...:ugh: |
