History
First flight1927

The Mono Aircraft Monoprep was an American light civil sporting monoplane of the late 1920s.

Development and operation

Mono Aircraft was founded in 1927 and their first design was the Monoprep high-wing sporting two-seat open cockpit monoplane. Eight Monopreps were built.

The improved Monoprep 218 followed the initial model in 1929, with a 3 ft (1 metre) shorter wingspan giving increased speed. 84 Monoprep 218s were built by 1930. One long-nosed aircraft was used to test one of the two Lambert H-106 engines during 1930.[1]

The sole surviving example of the Monoprep 218 NC179K was publicly displayed in airworthy condition in the Airpower Museum at Ottumwa Iowa.[2] It has now changed into private hands and is under restoration to fly again.
