Rotax engines are built in Gunskirchen, Austria by BRP-Rotax GmbH & Co. KG. Bombardier Recreational Products, Inc. was formed in 2003 by sale of the BRP activities by Bombardier, Inc. of Montréal, Québec, Canada. Bombardier, Inc. continues as an active aerospace manufacturer well-known for their business jets and and regional jet transports. Rotax was founded in Dresden, Germany in 1920, but operations were moved to Austria in 1943 and to Gunskirchen in 1947. The firm achieved success after WWII by building small engines for a variety of uses including snowmobiles from 1962. Success with the latter led to their acquisition by Bombardier to produce engines for Bombardier Ski-doos. Rotax has also achieved great success in engines for ultralight and light aircraft. This effort began in 1982 with two-stroke cycle single- and inline two-cylinder engines, production of which continue. In the mid-1980s, they began developing larger four-stroke cycle engines for lightplanes. Information on the current range of engines can be found on the Rotax Website and on that of their US distributor Kodiak Research. BRP announced early in 2003 that they were developing the normally-aspirated Bombardier V220 and its corresponding turbocharged V300T version (both formerly called the Rotax 936) aircraft engines. These are four-stroke cycle, liquid-cooled V-6 engines developing 220hp and 300hp, respectively, at 6000rpm, geared to 0.333 (KP10/03, 12/03; SA7/03, 8/03). BRP-Rotax announced in late 2006 (SA1/07) that certification of the 936 was imminent, but that a corporate decision had been made that production will not follow. Today, Rotax is the dominant international supplier of engines with less than 115hp for ultralight and light aircraft manufacturers around the world. This can be seen from the numbers of applications listed below for their four-stroke cycle engines, as well as many applications for their two-stroke cycle engines. They have reported the delivery of more than 100,000 aircraft engines. The Type Certificates (TC) listed below as LBA refer to certification by the Luftfahrt Bundesamt (Federal Office of Civil Aviation), the German equivalent of the FAA in the US. Certification is to the European JAR requirements.
*** Several versions of the Rotax 912, 912 S, and 914 have received Light Sport Aircraft (LSA) approval in the US during 2005. The firm has established their compliance with ASTM Standard 2339-04 for LSA engine design and manufacture. The specific compliant versions and applicable serial numbers can be found in SA5/05 and SP5/05. The compliant versions can be found below in the individual engine model writeups. ***
There are many light aircraft available that can accommodate more than one of the 912, 914, and 912 S engines. The applications below have a notation that has not been used elsewhere in this compilation. The notation is as follows:
Under the 912 (OL-74); Aircraft Model Name* means that 912 and 914 engines are alternatives.
Under the 912 (OL-74); Aircraft Model Name^^ means that 912 and 912 S engines are alternatives.
Under the 912 (OL-74); Aircraft Model Name** means that 912, 914, and 912 S engines are alternatives.
Under the 912 S (OL-82); Aircraft Model Name* means that 912 S and 914 engines are alternatives.

The 912 A was the initial production version under LBA TC = 4585 and is still available.
The 912 UL series is similar to the 912 F series; it has no type certificate, but can be used in experimental aircraft and in US Light Sport Aircraft with an applicable engine serial number. They can be geared to 0.446 as an alternative.
