I was looking into N484TS an noticed a CS prop. When I called the seller they said I could set the prop to meet the LSA limits and just placard the control inop.
Sounds to good to be true, and I know what they say about if it sounds to good to be true.
CS prop marked inop?

Re: CS prop marked inop?
The FARs are very clear. If an aircraft has ever been equipped and operated outside of the LSA rules, it can never be an LSA.

Re: CS prop marked inop?
Check me if I'm wrong, but I recall that the LSA requirements allowed a "ground adjustable prop", which, to me, would not include that which the OP was told.
Re: CS prop marked inop?
That is correct, Dan. A Constant Speed prop is not a ground adjustable prop, no matter how it is placarded.

Re: CS prop marked inop?
To add to the mix, there exist flight-adjustable props that are not constant speed.
But hardly relevant - none of them are sadly permitted for Light Sports - if they were, I'd spring for one in a heartbeat. A fixed pitch prop is similar to a car with one forward gear, albeit with a "fluid" clutch.

Re: CS prop marked inop?
Interesting Eddie. Could you possibly cite a few examples? Are some auto and/or self-adjusting?FastEddieB wrote:To add to the mix, there exist flight-adjustable props that are not constant speed.

Re: CS prop marked inop?
The simplest example is the two-position adjustable. Push knob for climb prop, pull for cruise prop (or maybe vice-versa; I can't recall).

Re: CS prop marked inop?
So if the plane can either be built as an lsa or an eab and you put a component on it that makes it perform outside a lsa it can never be an lsa again?

From the FAA definition,Atrosa wrote:So if the plane can either be built as an lsa or an eab and you put a component on it that makes it perform outside a lsa it can never be an lsa again?
Light-sport aircraft means an aircraft, other than a helicopter or powered-lift that, since its original certification, has continued to meet the following: (7) A fixed or ground-adjustable propeller if a powered aircraft other than a powered glider.
So if it has had other than a fixed pitch or ground adjustable it does not meet the definition.
Re: CS prop marked inop?
I think Hamilton Standard had a two position hydraulically operated prop. Then there is the Aeromatic two position prop that adjust automatically using flyweights. Also the Beech Roby that had an crank on the instrument panel. Some of the early Beech Bonanzas had an electric adjustable prop that was not constant speed. For the modern era, I think Neuform offers an electric adjustable prop that is not constant speed. It is installed on some CT's in other parts of the world.designrs wrote:Interesting Eddie.

Re: CS prop marked inop?
I do sort of know of a ELSA which has a prop that could be in-flight adjustable if the control was in a different location. As it is you have to make adjustments by accessing the control in the baggage compartment. I guess you could say it is electrically ground adjustable.
Re: CS prop marked inop?
Correct me if I am mistaken: A factory-built S-LSA can not be converted to an EAB... but it can be converted to an Experiential with proper history documentation.Atrosa wrote:So if the plane can either be built as an lsa or an eab and you put a component on it that makes it perform outside a lsa it can never be an lsa again?
The S-LSA plane can convert to Experimental... and one-time back to S-LSA (ONE-TIME ONLY, provided that the aircraft was not modified.)
For example, an S-LSA is factory equipped for IFR, but can not be flown in IMC as a LSA. The plane is converted to Experimental so that an instrument-rated Private Pilot can fly it IMC. To increase resale options, the unchanged Experimental may be converted back to S-LSA.

Re: CS prop marked inop?
I know of another SLSA that has a 2-position prop with the lever mounted to the engine side of the firewall. Since the engine has to be uncowled to switch between climb prop and cruise prop, this can't exactly be done in flight. So, it's considered ground adjustable, hence an LSA.

Re: CS prop marked inop?
You are correct, but some aircraft such as the Van's RV12 can be either SLSA, SLSA converted to ELSA, built as a ELSA, or built as a EAB. You can not convert an aircraft that has been issued a different airworthiness certificate to EAB.designrs wrote:Correct me if I am mistaken: A factory-built S-LSA can not be converted to an EAB... but it can be converted to an Experiential with proper history documentation.Atrosa wrote:So if the plane can either be built as an lsa or an eab and you put a component on it that makes it perform outside a lsa it can never be an lsa again?

Re: CS prop marked inop?
Well, sort of. An SLSA can be converted to an ELSA (but never an E-AB) by an agreeable DAR, but only if it was unmodified from its original SLSA configuration prior to conversion.designrs wrote: Correct me if I am mistaken: A factory-built S-LSA can not be converted to an EAB... but it can be converted to an Experiential with proper history documentation.
Not necessarily. A converted SLSA can be converted back only with the approval of the original manufacturer. Since such approval has liability implications, it is highly unlikely that the original manufacturer will grant such approval.The S-LSA plane can convert to Experimental... and one-time back to S-LSA
