INTRODUCTION
PURPOSE
The purpose of this manual is to provide guidance to RV-12iS owners, pilots,
mechanics, regulatory officials, and aircraft/component manufacturers that are certified
to perform maintenance, repairs, and alterations on the light sport aircraft covered in
this manual.
SUMMARY
This manual contains maintenance instructions for the RV-12iS light sport
aircraft. The RV-12iS is a single engine, fixed tricycle gear, full-cantilever monoplane.
The two-seat cockpit is enclosed with a tip-up windscreen/canopy. The occupants sit
side-by-side, aft of the engine and forward of the wing spar. Both of the wings are quick
removable. The flaperons remain with the wings and self-connect to the control linkage
when the wings are installed. The empennage consists of a vertical stabilizer, rudder
and stabilator with anti-servo/trim tab.
The airframe is a semi-monocoque aluminum structure, with some steel and
fiberglass parts. Fiberglass composite parts are used to finish some non-structural
portions of the aircraft.
The pilot and passenger board the aircraft from either side using the boarding
step and a reinforced area near the leading edge of the wing. The pilot is seated on the
left side (from within the cockpit) of the aircraft. A combination Electronic Flight
Information System (EFIS) and Engine monitoring System (EMS) with graphical user
interface is used to monitor and report flight and engine performance information to the
pilot.
The RV-12iS is equipped with either a Rotax 912ULS (with dual carburetors) or a
Rotax 912iS Sport (electronic fuel injection / FADEC) 100 hp four cylinder engine,
enclosed in a fiberglass composite cowling at the front of the aircraft. Engine power is
transferred via an integral gearbox to a Sensenich composite propeller.
The pilot and the passenger both have full flight and ground controls. Pitch and
roll is controlled from either control stick. The control sticks are linked by push/pull rods
and torque tubes to the flaperons, and linked by cables to a stabilator. The flaperons are
operated from a switch near the throttle controlling an electric linear actuator. Yaw is
controlled using rudder pedals linked by cables to a traditional rudder that is hinged to a
fixed vertical stabilizer. The rudder pedals have integrated left and right foot pedals that
are used to independently control the wheel brake on the corresponding side.

SCOPE
• NOTE: This maintenance manual is intended to be used in conjunction with
the RV-12iS Kit Assembly Instructions (KAI) when completing maintenance or
repair processes.
All of the service and maintenance requirements that are unique to the RV-12iS
S-LSA are included in this manual. The general service and maintenance duties that are
common to standard aircraft still apply to the RV-12iS regardless of the inclusion of
those requirements in this manual, so FAA Advisory Circular - Aircraft Inspection,
Repair, and Alterations, AC 43.13 is another valuable reference.
All inspection and maintenance and all maintenance log entries must be made in
accordance with 14 CFR / FAR’s and/or the aircraft’s Operating Limitations.
The manufacturers of third party components provide manuals that include
complete service and maintenance requirements that are specific to these components.
The current service and maintenance manuals from any third party manufacturer, such
as; engine, propeller, avionics, etc. always take precedence over the related content in
this manual. There are references to third party documentation in this manual, as well
as some supplementary information which is for convenience only. It is recommended
to refer directly to the manufacturer’s service manuals for complete service information
that is unique to applicable components.
The manufacturers that provide operating and/or maintenance manuals to use in
conjunction with this manual are as follows:
♦Rotax – engine
♦Sensenich – propeller
♦Matco – wheels and brakes
♦Grove – wheels and brakes
♦Dynon – EFIS / EMS, GPS
♦Garmin – EFIS / EMS, GPS and Nav/comm
♦TCW – Backup Battery
♦ACK – ELT
♦Odyssey – battery
♦EarthX – battery
♦Van’s Aircraft −RV-12 Kit Assembly Instructions (KAI).
The service and inspection portions of this manual indicate the minimum
certification requirements for a person doing maintenance or repairs on an S-LSA RV-
12iS in the United States. Certification requirements for service and maintenance may
vary around the world. It is essential to determine the correct and legal maintenance
and certification requirements applicable to the region in which the airplane is
registered. The documents necessary to determine these requirements for S-LSA in the
United States are as follows:
♦RV-12 Maintenance Manual
♦ Federal Aviation Regulations for Light Sport Aircraft Maintenance Technicians
