Three hundred L-Spatz 55s were built in Germany, 155 in France under the name Avialsa A.60 Fauconnet, and 16 in Italy as the Meteor MS-30 L Passero; production was discontinued in 1962.

It is a single-seater cantilever shoulder-winged sailplane with a cruising (max L/D) speed of 45 mph.

The single spar wing and tail were constructed using fabric-covered wood, whereas the fuselage consisted of steel tubing covered with fabric.

The longest known cross-country flight was more than 600 km from Burg Feuerstein, Germany to France.
