The Klemm L 26, later Klemm Kl 26, was a low-wing trainer aircraft built by Klemm.

Design and development

[edit]

The L 26 was a larger, reinforced development of the Klemm L 25.[1]

Like the L 25, the L 26 was a single engined low-wing monoplane with fixed conventional landing gear. Most variants were two-seaters with tandem open cockpits.

Operational history

[edit]

The L 26 was first flown in 1928 and entered production the following year and was produced until 1936.[2] The L 26 was also produced in the United States by Aeromarine-Klemm as the AKL-26.[3]

In 1931, Oskar Dinort won the Deutschlandflug [de] in an L 26 Va.[4] Other notable pilots of the L 26 included Ernst Udet and Elly Beinhorn.[5]

Surviving AKL-26 at Old Rhinebeck Aerodrome
