Introduction to Type Certification

In this video I provide a brief introduction into the type certification process, what it is and how it works.
If you want to take a look at the airworthiness regulations yourself, you can find the FARs
here: www.ecfr.gov/cgi-bin/text-idx...
and the EASA CS here: www.easa.europa.eu/document-l...

That was very good. Thanks man.

[@antoniomv9444]

Thanks Doc! Right I had an essay about what are the challenges for an aircraft to be certified, and this definetely cleaned things up for me. Have a great day

[@drj.a.pascoe2606]

Glad I could help. Good luck with the essay!

[@phillipworth666]

Great summary! My company is thinking of becoming a DOA part21J and this has really helped point me in the right direction for further research

[@naamya2254]

Thank you. Well explained.

[@pablobalboa1276]

Thank you pretty much, this video is healping me a lot with homework

[@drj.a.pascoe2606]

That's great to hear! Good luck with your homework!

[@ingenium5831]

Thanks for this short, but precise summary. Currently I am watching and reading things about TC process and AW to repeat these topics before assuming an airworthiness role in a design organisation.
And from this perspective, a small critics could be that you could add some words about the organization on the side of the applicant. E.g. what is DOA/POA, what AW roles exist in the industry (CVE, DCS,...).
Furthermore you start to explain the discussions on the panels which rules are applicable and which not. At this point you could introduce the terms Special Condition and Critical Review Item to give the viewer the official termonology.
But these are only critics to improve possible future versions and maybe these topics are getting too much into the detail. So again, thanks for the good summary :-)

[@drj.a.pascoe2606]

Thanks for the useful feedback, good luck in your new role!

[@shyamsrinivasan82]

elegant summary 🙂

[@drj.a.pascoe2606]

Thank you!

Great video Doc! Thank you so much. I read up EASA CS-E and did not find anything on hydrogen powered aircraft. Do regulations exist for such cases/are in the development phase?

[@drj.a.pascoe2606]

Indeed there are no specific regulations for hydrogen yet. It is likely those will be developed as more hydrogen powered aircraft are developed. In part 23, the regulations are already written in a more 'neutral' way so they can apply to different kinds of fuel or even non-fuel energy sources (e.g. batteries). But it's likely specific regulations for hydrogen will be needed. For the first hydrogen aircraft it's possible regulators will use the mechanism called 'special conditions', which you can think of as specific additional regulations to deal with certain novel features that are not covered by the normal regulations.

@@drj.a.pascoe2606 Thank you for your response Sir.

Hello Dr. J.A. Pasco, I was wondering if there are governing agencies other than the FAA and EASA that Type Certifies aircraft

[@drj.a.pascoe2606]

There definitely are! In principle type certification is handled at a national level, so all countries that have aircraft manufacturing industries will have agencies handling type certificates. So for civil airliners (part 25 in FAA / EASA language) that includes Brazil, Canada, Russia, and China for example. What often happens in practice is that the 'local' authority (FAA in case of Boeing, EASA in case of Airbus, and so on) will take the lead in the certification process and other agencies will take more of an observing role, maybe adding one or two specific points. Then when the 'lead' agency issues the type certificate, the agencies from other countries will accept that and only have a very short process to grant type certification in their own jurisdiction.

Dr. Pascoe, exc video. I am wondering if interested in teaching a regulations class in the caribbean. Let me know

[@drj.a.pascoe2606]

Possibly yes, but it would depend on various factors, including whether I have enough time and what aspects of regulations the course would have to cover. If you Google my name + TU Delft you should be able to find my staff page with contact details, that's easier for communication than TH-cam comments (which as you can see I don't monitor regularly)

[@aileronhelicopters]

Thank you for information. I would like to know how much it can cost to certify a 6 seats electric Helicopter and how long will it take. Thank you

[@drj.a.pascoe2606]

To be honest, I have no idea. Considering to my knowledge no electric helicopters are in service yet, it would likely take several years at least, and I wouldn't be surprised if the final cost would be in the millions.
