Lambach HL.I

10/31/2010. Remarks by Johan Visschedijk: "On January 30, 1931 students of the Technische Hogeschool (Institute of Technology) in Delft, headed by Dick Asjes, formed the DSA (Delftse Studenten Aeroclub, Delft Students Aeroclub). Ir. J.W.H (Hugo) Lambach was an aeronautical engineer and board member of the DSA for which he designed a small low-wing two-seat sports plane, designated HL.I.

Construction was started in Spring 1934 by members of the DSA, guided by professionals from the Pander Dutch Aircraft Factory. The aircraft wasfitted with a 45 hp Szekeley SR-3-0 three-cylinder air-cooled radial engine and Asjes took it to the air for the first time on July 3, 1935. Underpowered, the engine was soon replaced by a 90 hp Pobjoy Niagara seven-cylinder air-cooled radial engine. At the first lustrum of the DSA, January 31, 1936, the aircraft was appropriately registered PH-DSA and named Princes Juliana.

Six weeks later, March 13, the aircraft was transferred to the NLS (Nationale Luchtvaartschool, National Aviation School) for a brief period, as it was returned to the DSA on September 24, 1936. The aircraft survived the outbreak of the war in May 1940, but the German occupants stored it outdoors to rot away. It was broken up after the war in 1945."
