S-LSA converted to E-LSA

Talk about airplanes! At last count, there are 39 (and growing) FAA certificated S-LSA (special light sport aircraft). These are factory-built ready to fly airplanes. If you can't afford a factory-built LSA, consider buying an E-LSA kit (experimental LSA - up to 99% complete).

S-LSA converted to E-LSA

Postby c162pilot » Sun May 27, 2018 5:32 pm

Seeking advice from those of you who have taken your S-LSA to E-LSA. If you purchase a S-LSA aircraft and then transition it into the E-LSA category can you then make changes to the aircraft that takes it beyond S-LSA regulations? Example would be changing to a prop that causes the aircraft to exceed 120 KTIS. The reason I ask is that some S-LSA’s sold in the USA are certified to higher speeds in their country of manufacture but are modified to reduce there speed in the USA to qualify as a S-LSA.

No.

You could do that, but would have to placard it in such a way to stay below that speed in normal cruise. RPM limitation would be the most obvious way.

Thats a pretty interesting question. I have a Zodiac AMD built, converted to ELSA from SLSA. The registration and airworthiness certificate say Experimental, operating as a light sport. Once you take the aircraft out of it's operating limitations, I don't think you are able to go back. So if it's not an experimental operating as a light sport, what is it? Does it become a Experimental? How can it be, if the paperwork says operating as a light sport?
This is above my pay grade, hopefully Mel or some other DAR can respond to this.

I'm guessing it's experimental operating as light sport until it no longer meets the definition of light sport. At that time, it would become experimental. A Sport Pilot can only fly LSA, so I assume you would need a Private or better to fly it.

Experimental airworthiness certificates are issued under I think 9 different sub areas. You have to fall under one of them. Take a look at CFR 21.191 for the options. If you leave experimental operating as a light sport you don't have many options, Experimental R&D or Experimental exhibition would be your choices. Neither of which will have desirable operating limitations.

It doesn't change experimental categories. You simply have invalidated your airworthiness certificate. period

A simple way to look at it is it's still a light sport aircraft and it DOES meet all the definitions of a light sport airplane. I converted my SportCruiser and only have a sport pilot rating. Nothing changes except I'm now allowed to make any and all changes I want, myself. I no longer need a LOA/MRA or permission from the manufacturer or a LSRMA to work on it other than for my annual since I didn't take the class to do it myself. I cannot however make any changes that take the aircraft outside the definition of a light sport, that would violate the FAR's. (ie, a constant speed prop, etc.) I dont know what would happen if you did and why.

On the FAA website my registration now reads:

Classification: Experimental
Category: Operating Light-Sport Prev. issued cert under 21.190

There's more to the conversion but that's basically it in a nutshell.

There are two question raised here. Converting from S-LSA to E-LSA, not a problem. Making a modification that takes it out of the LSA definition, is a problem. For example, if you did something that raised the stall speed above LSA limits or put on a constant speed prop.

Correct Tim, in my opinion most make the switch to E-LSA to be able to make minor changes and do a lot of the work on their own plane. I also switched because my manufacturer, Czech Sport Aircraft, does not issue LOA/MRA’s for any reason. I simply wanted to upgrade my outdated 2007 avionics and the manufacturer would not allow it. In a nutshell, they suck.

I have no intention of making changes that would take my plane out of the definition of a light sport. Since I currently only hold a SP rating and I don’t even know what would happen if I did and what the new category would be. I also don’t think others are making these changes either, it’s really all about the freedom from the manufacturer and their rules. :mrgreen:
