When it was available the aircraft was supplied as a kit for amateur construction.<ref name="Aerocrafter">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]].<ref name="Aerocrafter" />

The aircraft is made from sheet [[aluminum]]. Its {{convert|35.50|ft|m|1|abbr=on}} span high [[Aspect ratio (wing)|aspect ratio]] wing employs a Marsden-designed IARV 419 [[airfoil]], mounts [[Flap (aircraft)|flaps]] and has a wing area of {{convert|136.00|sqft|m2|abbr=on}}. [[Winglet]]s 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.<ref name="Aerocrafter" /><ref name="KitplanesDec1998" /><ref name="Incomplete">{{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}}</ref><ref name="engines">{{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.<ref name="Aerocrafter" />

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 [[Jig (tool)|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.<ref name="Aerocrafter" /><ref name="KitplanesDec1998" /><ref name="KitplanesDec2001" /><ref name="KitplanesDec2003" />

==Operational history== By 1998 the company reported that 18 kits had been sold and three aircraft were flying.<ref name="Aerocrafter" />

In December 2013 four were [[Aircraft registration|registered]] with [[Transport Canada]] and one in the United States with the [[Federal Aviation Administration]].<ref name="TCCAR">{{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 }}</ref><ref name="FAAReg">{{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|archive-date = 24 December 2013|archive-url = https://web.archive.org/web/20131224110125/http://registry.faa.gov/aircraftinquiry/AcftRef_Results.aspx?Mfrtxt=&Modeltxt=GRIFFIN&PageNo=1|url-status = dead}}</ref>
