Light Sport Aircraft

The consensus standards have been released, you can order them from
www.astm.org
(Stock number: Aircraft04). It's an 80-page document, used in lieu of a
few
hundred pages of conventional FAR. Interesting read. The maintenance
standard
is still under discussion, but it will probably be out soon. The FAA is
having
its first course for DAR-LSAs this month, but I believe a standard DAR
(or, of
course, the local FSDO) can do the safety sign-off for a production LSA.

Is it correct to say that the consensus standards do not apply, when it is a
plans built? How about kit meeting 51% self built rule?

I'm still not exactly sure I understand what an experimental LSA is, and
what hoops must be jumped through.

An ELSA is simply an SLSA that has been pulled off the production line
at whatever point the customer wants. The customer then finishes the
planes following the EXACT factory instructions but it must be
identical to the SLSA. All factory parts and no modifications at all.

It is subject to the same maintaince ect requirements as SLSA but can
not be used for instruction or rental.

Sleepy is correct. The LSA regs do not affect the classic 51% homebuilts *at
all*. The same old process is in effect. If your 51% homebuilt meets the
definition of a Light Sport Aircraft (gross weight, stall speed, etc.) it can be
flown by a person with Sport Pilot privileges (either someone with an actual
Sport Pilot license, or someone with a higher license and an lapsed medical) but
the licensing and maintenance regulations are the same as they've always been.

One small point that I'll correct Sleepy on: The Experimental LSA is not quite
subject to the same maintenance requirements of a Special Light Sport Aircraft.

On the SLSA:

1. Preventative maintenance can be performed by the owner (just like FAR 23
aircraft).
2. Normal/major maintenance must be performed by an A&P or a person with a
Light Sport-Maintenance (LS-M) Repairman Certificate
3. Annual inspections must be performed by either an A&P or a person with a
LS-M Repairman Certificate.

For the ELSA:

1&2. Preventative AND Normal/major maintenance can be performed by the owner
3. Annual inspections must be performed by an A&P, a person with a LS-M
Repairman Certificate, or someone with the other new Repairman Certificate,
Light Sport- Inspection (LS-I).

The LS-I Repairman Certificate is similar to the Amateur-Built aircraft
repairman certificate, with two significant exceptions:

First, the applicant must complete a 16-hour training course. You can NOT
receive an LS-I just by assembling an ELSA. You MUST take the course.

Second, a person with an LS-I may perform the annual inspection on *any* ELSA
they own. Unlike the Amateur-Built Repairman Certificate, it is not applicable
to only one aircraft. Once you earn the LS-I, you can buy another ELSA kit or a
completed ELSA aircraft and perform the annual inspections on it.

Sleepy touches on one sporty item about the ELSA category. Like he says, the
ELSA kit *must* be built exactly to the LSA kit manufacturer's instructions.
You cannot install an alternate engine, use a different covering system, etc.
It must be built precisely to the manufacturer's callout.

However... as far as I can tell, the owner can then modify the aircraft however
they chose, once the plane receives its formal ELSA airworthiness certificate.

Owners of SLSAs (the production LSAs) must maintain their aircraft in precise
accordance to the manufacturer's maintenance plan and continued safety
directives to continue to conform to the consensus standard. But the FAA also
says that owners of SLSAs can avoid having to follow the SLSA's manufacturer's
safety directives by changing their plane's airworthiness to ELSA.

It follows, then, that ELSAs are NOT required to continue to comply to the
consensus standard, and owners can modify them once they've received their
original ELSA certification.

Sleepy is correct.

Whoops, noticed something else. I believe ELSAs *can* be used for instruction
and rental, through 2010. That's what's covering the two-seat ultralight
trainers that must convert to ELSA.

ONLY the "converted" (grandfathered) 2 seat ultralight ELSA's can be
used for instruction until 2010, you CANNOT by a new ELSA tomorrow and
use it for instruction.

Yes, on closer inspection, 14CFR 91.319 does limit the commercial use to the
converted 2-seat trainers. The "Light-Sport Aircraft Maintenance and
Certification Requirements" table near the beginning of the FAA release is a bit
deceptive....

Thanks, Ron. That's a keeper.

When you gonna write your LSA repair and building book? I'll buy one to
add to my collection!

Ron is correct about the maintaince and other details. To me the
differences between SLSA and ELSA are minor compared to the differences
between ELSA and amature built experimental.

Personally, my only reason to consider ELSA would be to avoid building
at least 51%. The restrictions and requirements associaed with ELSA
would easily outweigh that benefit in my opinion.

The world has become a lot more impatient... in nearly every conventional
hobby, people want to buy more and do less. People buy ready-to-fly RC models,
no one builds their own stereos, those who build their own computers basically
just plug ready-to-run components together. ELSA kits won't appeal to those who
want to customize their planes, but might be a good cost-savings opportunity for
those who don't want to do a lot of work.

The aspect that intrigues me is the SLSA to ELSA conversion. The FAA says that
owners of SLSAs will be able to convert their planes to ELSAs. Once it's in
ELSA, the plane apparently no longer has to continue to conform to the consensus
standards (the FAA says one can do the conversion if one doesn't want to
implement a change required by the manufacturer).

One of the more common homebuilding questions come from guys who want to take a
stock Cessna, install an auto engine in it, and "license it as a homebuilt." As
we've discussed here many times, it's almost impossible to transfer such a plane
to the Experimental Amateur-Built category.

However, it looks to me that such a switchover WILL be possible, within ELSA.
You still won't be able to do it with a Standard category airplane, but you will
be able to buy a flying aircraft (new or used SLSA), put it into the
Experimental category (ELSA), and then perform whatever modifications you please
with no further limitations by the FAA. You'll even be able to rent it out,
until the permission to do so expires in 2010. You'll be able to maintain the
aircraft yourself, and, with the completion of that 16-hour course, be able to
sign off the annuals.

I don't know if that was the intent of the developers, it sure looks like it's a
result of the program....
