The name Waco comes from the initials of the original company name, Weaver Aircraft Company, founded in the early 1920s. This aircraft was certificated in April, 1934, the model YKC became the company’s best selling model. They were comfortable, fast and well equipped. On September 28, 1934 an application for commercial aircraft license states was submitted. It showed the date of manufacture as September 1934. The application was approved and the aircraft number became NC14066.

A Repair and Alteration form states both propeller blades were straightened at the 30 Inch station. This form shows 24 January 1938 as the date of the accident that bent the blades. Another Repair and Alteration form dated 5 May 1938 states a splice was made on the rear spar carry thru and the motor mount. All wing fittings were removed and replaced. The aircraft must have flipped over as the landing gear wasn’t damaged.

This aircraft came to Alaska in Dillingham on 26 November 1939. The following January a Repair and Alteration Form shows the installation of Washington Aircraft skies, model 3600. From 1941 to 1988 Waco N14066 suffered a number of accidents, alterations, and repairs. Alterations included changes in the electrical system from 12 volts to 24 volts and back to 12 volts, changes of propeller types, changes of engines to increase from 225 horsepower to 300 HP, and additional windows in the cabin rear sides.

When WACO model YKC aircraft came from the manufacturing plant, their specifications were as follows even though they may have been modified at a later date.

The Alaska Aviation Museum purchased this aircraft on January 2, 1995. From February 1999 to June 2001 the aircraft underwent an extensive restoration by the staff and volunteers of the museum. This included major repairs to the wings, fuselage and empennage. A complete new interior was fabricated, new doors, both cabin access and baggage, were fabricated and the aircraft was recovered with Poly-Fiber products fabric and painted. During the restoration the rear windows were removed and replaced with fabric to bring the aircraft back to its original appearance.
