1945 American Champion PT-28A Spacewalker IISingle-Engine Piston Aircraft • McKinney, TX, USA

This Spacewalker II, registered as NX533 and carrying serial number 810, is a truly one-of-a-kind experimental amateur-built aircraft, billed as "The Only PT-28A In Existence." It was featured in the November 2022 issue of EAA Sport Aviation magazine. With just 98 hours total time on the airframe and 197 hours since new on its 100-horsepower Continental O-200A engine, this is a very low-time example. The airframe, including the steel tubing fuselage and tail assembly, is TIG-welded and powder-coated; the wings are wood and fabric with Poly-Fiber covering, which was last applied in 2020. The seller notes the aircraft has always been hangared...
