The Aeronca L-3 group of observation and liaison aircraft were used by the United States Army Air Corps in World War II. The L-3 series were adapted from Aeronca's pre-war Tandem Trainer and Chief models. The L-3 was initially designated the O-58 at the time it was first ordered by the Air Corps. The airplane was given its service tests in the summer of 1941 during maneuvers in Louisiana and Texas where it was used for various support purposes such as a light transport and courier.
