This 1974 Thorp T-18 (registration 118EK) presents as a well-documented project aircraft with 750 total hours and a fresh engine overhaul completed in April 2024. The Lycoming O-320 engine shows 0 hours since major overhaul (SMOH) with $32,234 in documented work by Ly-Con, featuring new Surefly dual magnetrons and a zero-time governor, though the Hartzell constant-speed propeller requires overhaul. The airframe is constructed entirely of aluminum with metal compound surfaces throughout, including the cowl, wingtips, and fairings - no fiberglass components.
The aircraft comes with basic VFR instrumentation including a KX 155 nav/com and dual rudder/brake controls, but requires reinstallation of the engine, replacement of rubber hoses, and brake system work to return to airworthy condition. Notably, this T-18 was built under John Thorp's personal guidance during construction and has been consistently hangared at APC. The sale includes valuable builder tooling - including cowl forms, jigs, and molds for aluminum parts - available separately for $2,000. The project represents an opportunity to complete a historically significant homebuilt with direct lineage to the designer's input.
