Windecker YE-5

Overview

The Windecker YE-5A was an experimental aircraft evaluated by the U.S. Air Force. It was an all-composite construction aircraft, based on the commercial single-engine, low-wing Windecker Eagle. The YE-5A, delivered in 1973, was used in tests relating to the radar detectability (commonly known as 'stealth') of composite aircraft. A single YE-5A (serial number 73-1653) was built. The YE-5A composite airframe benefited from the U.S. Army project and was shown to be difficult to detect using radar; however other components, including the metal engine, could be seen on radar. The YE-5A was destroyed in a crash during a classified project in 1985, and was replaced by a modified conventional civilian model Windecker Eagle (N4196G), to complete the project. This aircraft is disassembled and in storage in the United States Army Aviation Museum at Fort Novosel, Alabama.
