OVERVIEW
Engine information is taken from Rotax documentation. For complete engine
information refer to the Rotax engine documentation.
Note: Rotax is the primary
authority for specifying the level of certification required by an individual
performing maintenance or repair on a Rotax 912ULS or 912iS engine. Refer to
the Rotax documentation to determine the qualifications or training required for
any maintenance or repair action.
The top and bottom engine cowling are a formed composite of fiberglass cloth
and epoxy-resin. The cowl is attached using screws and segments of piano hinge.
Hinge also joins the top and bottom cowl halves together. Adhesive heat shielding
protects the inner surface of the cowl. On the 912ULS engine, there is a cockpit-
mounted throttle and choke control. On the 912iS there is only a throttle control.

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.
