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.
Design and development
|date= }} The L-3 was initially designated the O-58 at the time it was first ordered by the Air Corps, a designation prefix that was retired in April 1942. The airplane underwent service tests in the summer of 1941 during maneuvers in Louisiana and Texas.
When American forces went into combat after Pearl Harbour, the Army Air Force used the L-3 in much the same manner as observation balloons were used during World War I — spotting activities and directing artillery fire. It was also used for liaison and transport duties and short-range reconnaissance which required airplanes to land and take off in short distances from unprepared landing strips. Liaison pilots would train on L-3s before moving on to front-line aircraft like the Piper L-4 or the Stinson L-5. Some L-3s were shipped to north Africa, and subsequently given to the Free French Forces in the area at the time. At least one of the aircraft served with US forces in Italy.
The TG-5 was a three-seat training glider of 1942 based upon the O-58 design. This aircraft retained the O-58's rear fuselage, wings, and tail while adding a front fuselage in place of the engine. In all, Aeronca built 250 TG-5 gliders for the Army. The Navy received three as the LNR-1.
