Saw an RV-9A being promoted as a Light Sport at the Sebring Light Sport Expo. The plane had a Lyc. 0-235. The numbers don't seem to add up to qualifying as an LSA. Anybody seen this? Doesn't seem to leave much room for payload.

RV had a display across from Zenith (at) S&F last year, and made me this same
pitch, probably because I stated I was interestewd in the Zenith as an LSA.
It struck me the same way. I think trying to make an LSA out of an RV9A is a
bit of a stretch.

Of course, one wouldn't need to worry too much about overstressing the
aircraft, if one were somewhat over the 1320 lb limit. It might tax that
O-235 a bit, though.

Van's lists, for the RV9A, with 115 HP, at gross, cruise 55%, 8.000 ft, 148 mph; stall speed 48 mph. I really don't see how an RV9A could ever qualify as an LSA.

I also question the "E" in E-LSA. (ie. the RV12) To qualify, one must be built EXACTLY like a production model of the same airplane. That completely rules out experimentation. Isn't that what the "E" stands for ?

When I looked at Van's web site, I was confused by how they are trying to package the RV-12. My impression was that it will be/is available as an EAB and they are in the process of getting an E-SLA certification. I'm not sure how that works when you don't have an S-LSA, but apparently you can specify a virtual S-LSA that the E-LSA can be spec'ed from?

I agree Jay. I had plans for that plane. At the time they said there was no way to make the weight bogey for LSA. Plans gone. Sure would have made a terrific low and slow plane though... It would certainly fly and fly well with even an A-65 pitched for climb. Today's crowd just doesn't understand that planes do not have to suck fuel and go fast...

They are probably going to use one aircraft to get the LSA
certification. Then that first example will be the S-LSA and the E-LSA
kits will built to that pattern.

No, the Experimental category is just a catch-all for any airplane
that doesn't meet the requirements for either a Standard or Special
certificate.

Experimental is just the category the FAA assigns to any aircraft that
doesn't fall under any of the other categories of aircraft
certification.

Bryan,

Not to be argumentative, but the FAA and I disagree. E-LSA is an acronym for "Experimental Light Sport Aircraft." (look it up)

LSA or Light Sport Aricraft is a category that meets the LSA consensus standards, whether factory built or amateur built. To qualify as E-LSA, it must be built exactly like the production version LSA; no variance or Experimetation is allowed. Only the FAA would come up with a "Experimental" where no Experimenting is allowed. An "outsider" would probably have called it AB-LSA.

E-AB is any amateur built experimental. My 601XL is registered E-AB, but it qualifies as an LSA. It can be flown by a Private Pilot as an experimental airplane, or by a Light Sport Pilot as an LSA. It can not qualify as E-LSA.

I need to correct my earlier post. I should have stated that the
Experimental category is a catch-all for any airplane that doesn't
meet the requirements of any other category. Standard and Special are
not categories of certification, they are types.

The S-LSA and the E-LSA both fall under the same TYPE of airworthiness
certificate (Special) but they do not fall under the same CATEGORY of
airworthiness certificate. The S-LSA falls under its own category, the
Light Sport Aircraft category [21.190]. The E-LSA falls under a subset
the Experimental category, Operating light-sport aircraft [21.191(i)].
Technically the E-LSA should be called the S-E-LSA but E-LSA is good
enough to get the point across. An amateur built aircraft also falls
under a subset of the Experimental category, Operating amateur built
aircraft [21.191(g)].

The fact is that E-LSA does not just apply to LSA kits built to a
conforming S-LSA by an amateur builder, it also includes former "fat
ultralights" that may have been factory built or amateur built and it
includes factory built S-LSA aircraft that have since been converted
to E-LSA. So AB-LSA wouldn't fit very well either. That's probably why
they put it under the catch-all Experimental category.

It is also my understanding that once the test time is flown off, an E-
LSA built from a conforming kit pretty much falls under the same rules
as an E-AB as far as maintenance, repair and modifications are
concerned.

Bryan,

I just know the FAA has a secret group who's mission is confusion and obfuscation. They sit around a big conference table and have wild brainstorming sessions. The most outrageous suggestions are incorporated into the regs. "Boy, this one will REALLY throw them!" I'm sure that is how they came up with the ubiquitous and required "No one shall do so and so, unless...." Oh well, it keeps them busy, employed and amused.

PostPosted: Sun Jan 25, 2009 3:52 pm    Post subject: Re: RV9- Light Sport Reply with quote

When I got my 601XL registered as an E-LSA, it seemed very clear as to the advantages at that time. It appeared that there was a loophole in the Fat Ultralight ruling that allowed me to register the 601XL as an E-LSA with an auto-converted Corvair engine and still get only a 5 hour fly-off for Phase I. That was compared to the 40 hour fly-off for the E-AB. Also, there really wasn't an S-LSA at the time with a Corvair engine... and still isn't. But there were examples of flying 601XL's with Corvair engines and these were posted on Zenith's website. That satisfied the conditions of the E-LSA rule for fat ultralights.

Even though I built the plane, I had to take the LSA Repairman Course (16 hour) in order to perform the condition inspection, or I would need to get an A&P or higher to perform the condition inspection. My understanding was that anyone (including a child if I felt comfortable allowing it), could do repairs to the aircraft.

The big advantage for going this route was that upon selling the aircraft, the new owner could also obtain the LSA repairman certificate and could then perform the condition inspection themselves. Since the sale of the E-AB aircraft would either require the original owner to perform the inspection or an IA or A&P, this seemed to be a big advantage.

And last, during the taking of the Repairman Course, I was told by the instructors that any modifications to the aircraft that affected the W&B would require another Phase I test flight and appropriate notations in the log book. We discussed this at length since I hadn't gotten the wheel pants on yet and this type of addition would, by the rules, require another Phase I test. I think the instructor said that even a 1/2 lb addition to the Weight of the aircraft meant that Phase I needed to be started over. As to whether I needed to contact FSDO and advise them of this I will need to review but I think I only needed to make a log entry similar to the first that resulted in moving to Phase II.

If anyone has updated info on this, let me know.
