The ARV Griffin is a Canadian homebuilt aircraft that was designed by Dave Marsden of the University of Alberta and produced by Canada Air RV and later by AC Millennium Corp, both of Edmonton. When it was available the aircraft was supplied as a kit for amateur construction.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 135.

Both companies are out of business and production ended.
Design and development
The aircraft features a strut-braced high wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via doors, fixed tricycle landing gear, or, optionally conventional landing gear with wheel pants and a single engine in tractor configuration.
The aircraft is made from sheet aluminum. Its {{convert|35.50|ft|m|1|abbr=on}} span high aspect ratio wing employs a Marsden-designed IARV 419 airfoil, mounts flaps and has a wing area of {{convert|136.00|sqft|m2|abbr=on}}. Winglets were a factory option to improve low speed handling, lateral control and STOL performance. The cabin width is {{convert|47|in|cm|abbr=on}} and the wings detach for ground transportation or storage. The acceptable power range for the Griffin Mark III is {{convert|65|to|150|hp|kW|0|abbr=on}} and the standard engines used are the {{convert|100|hp|kW|0|abbr=on}} Continental O-200A, {{convert|80|hp|kW|0|abbr=on}} Rotax 912, {{convert|74|hp|kW|0|abbr=on}} Rotax 618 two-stroke or the {{convert|100|hp|kW|0|abbr=on}} CAM 100 powerplants. Mounts were also available for the {{convert|130|hp|kW|0|abbr=on}} Subaru EA81, {{convert|108|hp|kW|0|abbr=on}} Lycoming O-235 and Suzuki engines.{{Cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|accessdate = 21 December 2013|last = Lednicer|first = David|year = 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|archive-date = 20 April 2010|url-status = dead|df = dmy-all}}{{cite web|url = http://www.arvcorp.com/carv/c-03-5.htm|title = Canada AIR R.V.

The Griffin Mark III has a typical empty weight of {{convert|840|lb|kg|abbr=on}} and a gross weight of {{convert|1500|lb|kg|abbr=on}}, giving a useful load of {{convert|660|lb|kg|abbr=on}}. With a full fuel load of {{convert|37|u.s.gal}} the payload for pilot, passenger and baggage is {{convert|438|lb|kg|abbr=on}}. The seats are fully adjustable and removable.
The fitting of floats and skis was listed as being under development in 1998. The Mark III kit included all-aluminum parts cut and bent, with fuselage, wing and tail assemblies pre-jigged. The aircraft could be bought as four separate sub-kits. The manufacturer estimates the construction time from the supplied kit as 800 hours for the Mark III and 600 hours for the Mark IV.
Operational history
By 1998 the company reported that 18 kits had been sold and three aircraft were flying.
In December 2013 four were registered with Transport Canada and one in the United States with the Federal Aviation Administration.{{cite web|url=http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp |title=Canadian Civil Aircraft Register |accessdate=21 December 2013 |last=Transport Canada |date=21 December 2013 |url-status=dead |archiveurl=https://web.archive.org/web/20110718042755/http://wwwapps2.tc.gc.ca/Saf-Sec-Sur/2/ccarcs/aspscripts/en/quicksearch.asp |archivedate=18 July 2011 }}{{cite web|url = http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=GRIFFIN&PageNo=1|title = Make / Model Inquiry Results|accessdate = 21 December 2013|last = Federal Aviation Administration|date = 21 December 2013}}
