Specifications

1996 Diamond Katana A1

Overview
The DA20-A1 Katana is a two seat aircraft designed and manufactured by Diamond Aircraft Industries of London, Canada. It is principally intended for primary flight training. The DA20-A1 Katana features advanced composite structure, single engine, conventional configuration with low wing, T-tail, and tricycle landing gear. The design of DA20-A1 Katana is based on the DV20 Katana, designed and manufactured by Diamond (HOAC) Aircraft of Austria. The DV20 was type certified by Austrian and German Airworthiness Authorities in 1993, and by Canadian and American Airworthiness Authorities in 1994. The principal differences are detail design improvements and changes to facilitate production with usage of North American standard parts and materials.

Powerplant
The engine is a Rotax 912F3 with a take-off power rating of 81HP (DIN). The 912F3 is a horizontally opposed 4-cylinder, 4-stroke engine. It features liquid cooled cylinder heads, dual ignition, dry sump lubrication, dual carburetors, and a propeller drive reduction gear box (2.2727:1). The engine features an integral 20A alternator directly driven by the crankshaft and a 40A alternator which is belt driven off the pulley that is mounted to the propeller drive flange. The DA20-A1 Katana uses the 40A alternator to power avionics, instruments and electrical accessories. The integrated 20A alternator is used exclusively to power the dual capacitance discharge, electronic ignition system. The engine mount is of conventional welded steel tubing construction. The hydraulically controlled, 2 blade constant speed propeller is the Hoffmann HO-V352F. The prop blades are of wood core construction, with composite skins and aluminum or polycarbonate bonded edge inserts. The GRP firewall is clad with insulating Fibrefrax and stainless steel skin. Cowlings are fire protected by fire resistant paint.
