Certifying a new aircraft under the LAA…

[Grob Driver]

Hello,

Can you help me with a query?...

If I were to replicate a single engine, single seat monoplane, what would be the process for getting the aircraft certified to fly under the LAA?

Kind regards
GD

Ring Turweston and start from there.

Or put a lot more detail on here about what you mean by 'replicate'.

And then ring Turweston - oh, I said that already.

You could also look at the raft of technical leaflets on the LAA's website, corresponding Technical Information Leaflets on the BMAA's, and CAP 733 on the CAA's website.

That description basically covers everything from a VP1 to a Mustang.
Do you want to narrow it down a bit?

'replicate'? You got one of those Star Trek gismos? Can you replicate me lots of £10 notes while you are about it, please?

You will probalby have to read CS-VLA, or if you want to build it as a microlight BCAR section S. The LAA require designs to be broadly complient with one of these codes.

Possibly not - there are loopholes which allow an authentic replica of a known good type to be built and receive a PtF. It all rather depends upon what it is - if, say, you wanted to build a replica Minimax, well the type has such a good record it'd be mostly a case of proving that you'd authentically copied the original design. If you wanted to build a replica Sopwith Camel, well it's got no track record as a civil aircraft, so you'd be treating it as a new type. At the other end of the scale would be something like a Huntair Pathfinder or Midland Ultralights Sirocco, which are specifically banned from flying in the UK, so any "replica" would have to be a substantial redesign.

Sorry, I should have been a bit more specific.... I want to build one of these...



It's a Hillson bi mono built in the 1940's. Only one was ever built, and I cant find any plans so I would effectively be building a brand new aircraft. Steel tube construction, with a plywood cover.

Of course calling the LAA is the best place to start, but the person I need to talk to wasn't there yesterday, hence me asking here. I'll call them on Monday!

Can imagine a few litters of kittens at LAA if you plan to build it to original spec, and drop the upper wing once airborne...

[Grob Driver]

Ye, I cant see them liking that idea either! I would plan to build it as a straight mono plane.

That's going to be a new design job, almost certainly approved under LAA amateur design/build procedures to CS.VLA (or either BMAA or LAA as a Microlight to BCAR Section S, which may well be the easier route). Loads of information on both organisations' websites about that to work from, also some excellent textbooks: I'd start with Darrol Stinton's "Design of the Aeroplane".
