Are you still planning to do that?

"•Most mechanics learn their skills from aviation maintenance
technician schools approved by the Federal Aviation Administration
(FAA). Training programs generally last 12 to 24 months, although some
schools also offer 2- and 4-year degrees. A small number of mechanics
receive their training on-the-job from experienced mechanics. However,
due to FAA rules, their work must be supervised and documented by
certified mechanics until they become FAA-certified. Consequently,
most employers only hire FAA-certified mechanics.

Certification
•The FAA requires that all mechanics who perform maintenance work on
aircrafts be certified or perform the work under the supervision of a
certified mechanic. The FAA offers certifications in airframe
mechanics (A license) for airplane body work, and powerplant mechanics
(P license) for engine work. Some mechanics obtain either the A or P
license.

To qualify for certification, in general a candidate must be at least
18 years of age, able to read and write English, and pass written,
practical and oral tests. To maintain their certification, mechanics
must have accumulated at least 1,000 hours of work experience in the
previous two-year period or take a refresher course."

So are you planning to do all that before you modify a LSA to increase the
cruise speed, which will invalidate the airworthiness certificate no matter
who does it?

1) Modifying an experimental airplane that originally met LSA criteria
to
go faster than LSA speed is not illegal. It simply means that from
that
time forward, it can't be flown solo by a pilot operating under LSA
flight
rules. It requires a private pilot or higher. (Even if the airplane
mods
are later removed, it still can't be flown under LSA rules anymore.)


2) Also, for the record, the FAA speed requirement for LSA has some
important qualifiers that allow LSA airplanes to legally travel faster
than
120 kts. Here is the FAA text:


"A maximum airspeed in level flight with maximum continuous power (VH)
of
not more than 120 knots CAS under standard atmospheric conditions at
sea
level."[1]


The true airspeed of most LSAs will increase with increasing altitude
(to a
point - most aren't turbocharged. Turbocharging isn't per se
prohibited by
the LSA rules. And are generally limited to 10,000 ft anyway.) Owners
of
some LSAs have in fact observed true airspeeds at altitude of 150 mph
or
more. They aren't in violation of the rule because the limit is
defined at
sea level under standard conditions.
