The SAI KZ III Lærke ("lark") was a Danish light utility aircraft used by the Danish Air Ambulance Service and Danish Air Force.
The first KIII was built during the German occupation of Denmark and first flew on 11 September 1944. With German permission it was transferred to the Redningskorpset (Rescue Service). A second war-time example was smuggled to Sweden. The two wartime aircraft had 90 hp (67 kW) Gipsy Minor I engines.
The KIII had a high wing braced by V-struts to the lower fuselage. Its fuselage had a steel tube structure and, like the rest of the aircraft, had fabric covering. Its two front seats shared dual controls. Slotted flaps and fixed, full span slots provided a gentle stall.
64 were built post-war with 100 hp (75 kW) Blackburn Cirrus Minor II engines. Many of these went to flying clubs, mostly in Denmark but with sales to several near-by countries. A few went further, one to Singapore and another to India, where its airframe still survives.
