The aircraft is made from mixed construction, consisting of welded steel tubing, with its flying surfaces covered in dopedaircraft fabric, plus fiberglass for the hull and other parts. Its 36.00 ft (11.0 m) span wing has a wing area of 150.00 sq ft (13.935 m2) and folds for storage or ground transport, without disconnecting the controls. The wing is supported by "V" lift struts with jury struts.[1] The Catalina wings had the option of mid-wing sponsons, or the original Amphibian droop wing tip sponsons for water operations.[7]
The Catalina has an empty weight of 600 lb (270 kg) and a gross weight of 1,200 lb (540 kg), giving a useful load of 600 lb (270 kg). With full fuel of 17.5 U.S. gallons (66 L; 14.6 imp gal) the payload is 495 lb (225 kg). While the 17.5 U.S. gallons (66 L; 14.6 imp gal) fuel tank is standard equipment, the factory also offered optional 31.5 U.S. gallons (119 L; 26.2 imp gal) and 45.5 U.S. gallons (172 L; 37.9 imp gal) tanks. The earlier Amphibian model offered only 17.5 U.S. gallons (66 L; 14.6 imp gal) standard fuel, with a total of 28 U.S. gallons (110 L; 23 imp gal) as two 14 U.S. gallons (53 L; 12 imp gal) tanks optional.[1][12]
The Avid Amphibian and Catalina could also be built without water operations capability. This variation of the aircraft was dubbed the "Landphibian", and was lighter without the inboard and outboard sponsons. In 1992 the Amphibian kit cost US$16,695, while the land-only version kit was US$15,695.[12]
The manufacturer estimated the construction time from the supplied kit as 700 hours.[1]
Operational history
By 2001 the company reported that 100 examples of the Amphibian/Catalina were flying.[2]
One builder, Rod Snider, of Boise, Idaho, wrote, "I completed the land version of the Avid Amphibian in January of 1987. Since then I have flown this remarkable little plane for 1960 hours. It is really a superb plane for sightseeing and flying slow and camping in back country airstrips. Three people of medium build can be carried comfortably, as can two people and all necessary camping gear with full fuel."[1] This aircraft was reported as destroyed in January 2004.[14]
