The Koolhoven F.K.44 was a two-seat, single engine sport monoplane designed and built in the Netherlands in the early 1930s.
It was powered by a 115 hp (87 kW) four-cylinder inverted inline Cirrus-Major engine driving a two blade propeller.
The seats were placed under the wing, surrounded with cabane struts, with a large rectangular cut-out for enhanced visibility in the trailing edge.
[2] It was owned by Jacob Mees, a banker who punningly christened his Koolhoven the "Koolmees" or "Great Tit" in English.
[1] The following year Mees gave the Rotterdam Aero Club the use of his aircraft,[1] but it was destroyed in June 1933, during an emergency landing at Castricum[2] following an engine failure.
