Kasper Bekas 1-A

The Bekas, which first flew in 1968, was a development of an earlier, 1959, design of Stefan Brochocki, the BKB-1. The design of the Bekas 1-A had three main aims : a higher L/D (archieved by using a greater span and aspect ratio), easier ground handling and rigging and a flexible wing to study the effect of bending on stability and controllability. It has a fixed gear and trailing- edge control surfaces on the out-board portion of the wing which serve a dual role of elevator and aileron.
Construction was wood and plywood.

Karo Aviacijos ANBO II

The ANBO II was a parasol-wing monoplane aircraft built by Karo Aviacijos Tiekimo Skyrius in Lithuania in 1927 as a pilot trainer for the Army. Designed by Antanas Gustaitis, it was the first Lithuanian trainer aircraft of own design.

Anbo stands for “Antanas nori būti ore”, which means “Antanas wants to be in the air”.

First flying on 27 November 1927, the plane was not produced in series, yet it served as a prototype for latter trainers Anbo-III and Anbo-V/51, developed by Antanas Gustaitis.

It was eventually reequipped with more powerful engine for the Aero Club of Lithuania in 1931 before being written off after a crash on 26 June 1934.

A full size flying replica was built in 2012-2016 by Rolandas Kalinauskas and Arvydas Šabrinskas. Due to difficulties in obtaining original Walter engine, a Russian-made Shvetsov M-11 engine, having similar parameters, was used. Test flight of the restored Anbo II took place on 18 October 2016. The plane is based in Pociūnai airfield, Lithuania and is mostly used for air shows with both constructors dressing in Lithuanian Air Force uniforms of 1920s-1930s.

Arvydas Šabrinskas

The Lithuanian plane had stopped at Priekuļi airfield, just outside Cēsis, Latvia, to refuel, en route to its destination in Biržai, northern Lithuania. After refueling, it attempted to take-off, but crashed following engine failure a little before 13:30, August 8, 2021. The engine failed during a climb at the altitude of 20-30 m resulting in a fatal crash for both the pilot Arvydas Šabrinskas, and the aircraft. The passenger is Valdas Černius, was taken to a hospital with serious injuries.

The plane crashed just outside Cēsis in Latvia

Kari-Keen 60 Sioux Coupe / 90

Kari-Keen Sioux Coupe 60, N244K

The Kari-Keen 90 Sioux coupe was designed by Swen Swanson and is a two-seat side by side high-wing monoplane with conventional landing gear. The wing is fully cantilevered, with skylights built in. The fuel tank sits above the pilot’s head and is part of the leading edge. Ole Fahlin built all the propellers and test flew the aircraft.

Production of the Sioux coupe began in 1929. The first model, the Kari-Keen 60 Sioux Coup, featured a 60 hp (45 kW) Veile M-5 engine. 22 aircraft were built without a type certificate.

Coupe 90-A

In 1930, six more model 90s were built with a type certificate. The price was US$3,365 in 1930.

In 1931, the Sioux Aircraft Corporation bought the company assets, changing the name of the Kari-Keen 90 into the Sioux Coupe 90.

1931 Kari-Keen Coupe built by Sioux Aircraft Corp

One 1930 Coupe 60 (ATC 2-81), powered by a 65hp Velie M-5 engine, was carried over from Kari-Keen inventory to Sioux Aircraft Corporation.

With the re-organization of Kari-Keen Aircraft Co, the 1931 Sioux Coupe 90 was a slight variation of the Kari-Keen 90. Designed by Swen Swanson and redesign by Gazley & LaSha, the one built, NC10544, sold for $3,355. Originally powered by a 90hp Brownback Tiger, it was later re-powered with a 110hp Warner Scarab.

The Sioux Coupe 90-B Junior (ATC 414) built in 1931, NC10721, sold for $3,500. Originally powered by a 90hp Warner engine, there are reports that a 90hp Lambert was also installed at one time.

The Sioux Coupe 90-C Senior (ATC 2-356) NC10735 was built in 1931.

Production of the Sioux coupe ended on 1 August 1933.

Karhumäki Bear

Niilo and Valto Karhumäki started in autumn 1924 the construction of an airplane at their home. The work also involved Emil Kankaanpää and Hope Hovinen. The machine was given the name Bear 1.

The brothers built in the 1920s of four aircraft: Bear 1 Bear 2 Bear 3 and Tern. Construction was initially something of a hobby, but soon expanded into a versatile aviation business.

Karhumäki Karhu 48B

Karhumäki Karhu 48B

The Veljekset Karhumäki O/Y company had been formed in 1924 and concerned itself with licence manufacturing. During 1946-1947 the company designed and built the Karhu 48B a high-wing strut-braced four-seat monoplane in collaboration with Valtion. The development team included Uuno Karhumäki, Matti Hahka and August Puukko from Karhumäki and Torolf Eklund, Johannes Joensuu, Oiva Lounivuo, Toivo Mäntysalo, Karl Konrad Wessman, Paavo Paitula, Olavi Raitio and Aaretti Nieminen from Valtion, Nieminen being appointed team leader.

WINGS: High-wing rigidly braced monoplane. Wing braced by steel-tube V-struts. Two-spar wooden structure covered with fabric. Flaps and ailerons with welded steel-tube frames and fabric covering.

FUSELAGE: Welded steel-tube structure covered with fabric.

TAIL UNIT: Braced monoplane type. Welded steel-tube framework covered with fabric.

LANDING GEAR: Tail wheel type with interchangeable wheels and skis. Faired side vees, incorporating springing, and two half axles hinged at centreline of underside of fuselage. Steerable tail wheel. The landing gear could be replaced by twin all-metal single-step floats of Karhumäki design and construction, with a rudder on port float.

POWER PLANT: One 190 hp Lycoming O-435A six-cylinder horizontally-opposed air-cooled engine driving an Acromatic 220 variable-pitch airscrew.

ACCOMMODATION: Enclosed cabin seating four, two single seats in front with removable dual controls and a full-width seat aft. Entrance door on each side. Two baggage compartments. Cabin heating and ventilation. Radio fitted as standard.

Two prototypes were completed, the first, registered OH-VKK and named Nalle, was flown for the first time by Uuno Karhumäki (the youngest of the Karhumäki brothers) on July 20, 1948. The second, which flew later that year, was registered OH-VKL and named Tavi. Planned production did not materialize by the import of cheap military surplus aircraft, and subsequently both aircraft were used by Karhumäki.

Karhumäki Karku 48B (OH-VKL c/n 6) “Tavi”

OH-VKL eventually had its wing modified and was redesignated Karhu 48B, it was reregistered OH-KUA in 1961 when it was sold to O. Marjamäki in Vilppula. After being deregistered in 1973, the aircraft eventually ended up at the Suomen Ilmailumuseo (Finnish Aviation Museum), restored by Karair in 1988 into the original livery and registration.
