L-16B (7AC)

Aeronca L-16B Grasshopper

National Warplane Museum

The Aeronca L-16 is a postwar military adaptation of the popular civilian Aeronca 7AC Champion, continuing the tradition of light liaison and observation aircraft first established by the Piper Cub during World War II. These small, nimble aircraft provided the U.S. military with affordable, highly maneuverable platforms for a variety of support roles during the early Cold War period.

Background

Following WWII, the U.S. military recognized the value of small liaison aircraft for observation, artillery spotting, and short-haul logistics. The Aeronca Champion was modified into the L-16 series, with the L-16B featuring an upgraded 90-horsepower engine for improved performance. While similar in appearance to its civilian counterpart, the L-16B incorporated military radios and equipment suited for battlefield support missions. L-16s served primarily with the U.S. Army and National Guard throughout the 1940s and 1950s, often filling roles previously handled by earlier Grasshopper variants like the Piper L-4.

Use & Purpose

The L-16B performed short-field reconnaissance, artillery observation, search and rescue support, and general liaison duties. Its simplicity, reliability, and excellent short takeoff and landing capabilities made it ideal for forward area operations, often from makeshift airstrips close to combat zones.

Museum Example

• Aeronca L-16B Grasshopper (Converted 7AC) (Manufacturer’s No. 7AC-3518 / N# N84804)

Built in 1946 as a civilian Aeronca 7AC Champion, this aircraft was later converted to L-16B configuration, reflecting the military adaptations used during the early Cold War era. For many years, the aircraft was owned by a Museum member who regularly flew it to Geneseo for the annual airshow. In 2020, the aircraft was purchased by another Museum member and is now based full-time at the Museum. It remains fully airworthy and flies regularly, offering visitors an active example of the small liaison aircraft that played an important but often overlooked role in military aviation history.
