engine swap

Can you change engines on a LSA -EAB or must the plane be a SLSA oe ELSA

There is no such category as LSA-EAB. There are Experimental Amateur Built aircraft whose operating parameters and limitations fall within the Light Sport Aircraft requirements but when an aircraft as certified as EX-AB that is what it is. There is no LSA designation in the airworthiness or operating limitations for EX-AB aircraft. You can change the engine on an EX-AB aircraft without issue but will need to put it back in phase 1 flight testing and if you changed the weight and/or cruise speed or stall speed then it may no longer qualify to be flown under the LSA rules. SLSA are factory built or factory spec'd kits and you can not change the engine on them unless that engine is already an approved configuration by the factory. ELSA are typically heavy or two place ultralights that were grandfathered in. I am not sure what their limitations would be.

elsa is also a kit version of a slsa. the most well know would be the RV-12. the weird part is under the rules, to get the elsa certification you must build it exactly as the factory slsa is built. once certified, you can change what ever you want. clear as mud isn't it?

Thanks Im somewhat new to the current limitations. there is supposed to be new weight limits,prop gov's in 2023
