The process was developed jointly by the Haskelite Manufacturing Corporation as Plymold and the Fairchild Engine and Aircraft Corporation as Duramold.[2] The plywood employed heat, pressure, plastics and wood to make complex structures in less time than could be done with aluminum construction. The Haskelite Corporation used this plywood for railway cars, buses, automobiles, and boats. Fairchild created its own use of the technology for making airplane structures.[3]


The Model 46 is a low-wing, cabin aircraft, with conventional landing gear and structures made using Duramold processes. The fuselage is constructed of two halves bonded together. The wings use wooden spars with plywood covering. The control surfaces use aluminum frames with aircraft fabric covering. A 50 U.S. gallons (190 L; 42 imp gal) fuel tank was mounted in each wing.[citation needed]

Operational historyEdit

In 1947 the Model 46 prototype was re-engined with a Pratt & Whitney R-985 and flown for ten years.[4]
