The Aircraft Electronics Association's international membership continues to grow. Currently, the AEA represents avionics
businesses in more than 40 countries throughout the world. To better serve the needs of the AEA's international membership,
the "International News and Regulatory Updates" section of Avionics News offers a greater focus on international regulatory
activity, international industry news and an international "Frequently Asked Questions" column to help promote standardization.

News & Regulatory Updates
Repair stations can test and inspect
equipment on experimental aircraft
In answering a question posed by the Aircraft
Electronics Association whether a certificated repair
station may perform maintenance described in Part 43
and required by §§ 91.411 and 91.413 on experimental
aircraft, the Federal Aviation Administration responded
that, "We have identified no FAA regulations, including
§ 145.201(b), that would prohibit a certificated repair
station from performing maintenance for an owner or
operator who seeks to bring an experimental aircraft into
compliance with §§ 91.411 and 91.413."
On April 27, 2015, the AEA requested a legal interpretation regarding whether a properly rated repair station
may perform tests and inspections on altitude-keeping and
transponder equipment for experimental aircraft (i.e., aircraft with experimental airworthiness certificates), in light
of the fact that Parts 43 (maintenance, preventive maintenance, rebuilding and alteration) and 145 (repair stations)
of Title 14 of the Code of Federal Regulations (14 CFR)
specifically do not apply to experimental aircraft.
The FAA stated that, "Furthermore, because Part 145
specifically does not apply to certain experimental aircraft, neither does the prohibition in § 145.201(b), that no
repair station may 'maintain or alter any article for which
it is not rated.' In other words, if an experimental aircraft,

or a component of an experimental aircraft, is outside the
scope of Part 145, then § 145.201(b) does not prohibit a
repair station from performing maintenance on that aircraft or component."
The FAA concluded that, "We have identified no FAA
regulations, including § 145.201(b), that would prohibit
a certificated repair station from performing maintenance for an owner or operator who seeks to bring an
experimental aircraft into compliance with §§ 91.411 and
91.413. Furthermore, although many experimental aircraft
are categorically excluded from Parts 43 and 145, those
aircraft are not excluded from §§ 91.411 and 91.413,
which impose certain Part 43 requirements. Finally, §§
91.411 and 91.413 require the equipment discussed in this
interpretation to be tested by certain specified individuals
or organizations and, as you state in your letter, in many
cases a Part 145 repair station is the only viable option for
the owner or operator of a general aviation aircraft."
Based on this FAA legal interpretation, altimeter system and altitude reporting equipment tests and inspections
(§ 91.411) can be performed on an experimental, amateurbuilt aircraft by any certificated repair station properly
equipped to perform those functions and holding:
1. An instrument rating, Class I.
2. A limited instrument rating appropriate to the
make and model of appliance to be tested.
3. A limited rating appropriate to the test to be performed.
4. An airframe rating appropriate to the airplane, or
helicopter, to be tested.
ATC transponder tests and inspections (§ 91.413) can
be performed on an EAB aircraft by any certificated
