A high-wing monoplane with a very large Plexiglas greenhouse canopy providing outstanding visibility for the pilot and observer. The Lycoming O-435 flat-six engine is installed in a neat close-fitting cowling, and the fixed undercarriage is light and simple.

History

Adopted in 1941 and produced through 1945 with over 3,500 built, the L-5 served in every theatre of the war. It was used for artillery spotting, medical evacuation, courier duties, and clandestine agent insertion in Burma and the Pacific.

Variants

The L-5A introduced a litter hatch for casualty evacuation; the L-5B had an improved radio fit; the L-5C and later marks incorporated further refinements. A total of six variants were produced.

Where you'll see it

The L-5 served with the US Army Air Forces and US Marine Corps worldwide, and was supplied to Allied air forces under Lend-Lease. Some examples continued in USAF service through the Korean War era.
