Luscombe 50 / 8 Silvaire

luscombe8


The 1937-1938 Model 8a, of which 1,100 were built, and the 1940 Silvaire, of which production had reached 6,000 by 1961.

The Luscombe Model 8 was the result of the new Continental A-50, dual ignition, 50 hp, flat four engine of 171 Cu.in that became available in early 1937. To promote the new engine, Continental made arrangements with Don Luscombe to accept (on loan) one of the new engines, hoping he might consider designing an engine around it. He accepted and engineers Fred Knack and Jim Rising designed the craft.

The Luscombe 50 (named after the engine) was designed as a high wing monoplane of all metal construction but with metal framed two-seat all-metal light aircraft.

As this was taking place, the metal framed, fabric covered ailerons were changed to corrugated metal, as were the rudder and elevator.

The prototype featured a control wheel on the left side of the cockpit. This was later replaced with a stick after complaints of poor control inputs.

The first flight of the production prototype Luscombe Model 8, NX1327, was made on 6 June 1938. On 11 August 1938, CAA Certificate #693 was issued.

The first Model 8 was basic, with only a tachometer, engine oil temperature gauge, altimeter, and airspeed indicator. Optional was a compass. The series was delivered standard with a tail skid. Floorboards were covered with carpet. Behind the cockpit a baggage compartment was beneath a 14 US gallon fuel tank, the seat swinging forward for access. The seat sat on the cabin floor and wasn’t fastened in any way.

By the end of 1938, Luscombe had built 71 Model 8s. The first of the series, models A-C, were fitted with fabric covered wings on a metal frame. The Model E used a forward squared wingtip, while models A to C were rounded. Model F had squared tips for and aft. The model 8E of 1946 2 place side-by-side high wing metal monoplane.

In all there were 15 model, each differentiated by engine or other changes. Engines varied from 50 to 90 hp with cruise speeds ranging from 95-110 mph. 113 Luscombe 50 were built.

Late in 1938, Continental introduced the 65 hp A-65 engine, with increase power through raising the A-50 rpm to 2300.

One of the first A65s was installed in January 1939 proving successful, and the Luscombe Model 8A replaced the Luscombe 50, which was then phased out.

At end of Second World War production tooling for Model 8 Silvaire was moved by Luscombe Airplane Corporation to Dallas, Texas. The postwar company, based at Dallas, Texas, went bankrupt in 1949 and was brought by Temco Aircraft Corporation which built about 50 Silvaires under the old name. In 1955 the Silvaire Aircraft Company acquired rights and equipment for Model 8 Silvaire, inaugurated production at Fort Collins, Colorado, and flew first aircraft off line September 1956.

In 1962 Alaska International Corp acquired from Silvaire Aircraft Company all rights to the Luscombe Silvaire

Renaissance Aircraft announced in 2002 the plan to manufacture an updated version of the single engine, two seat, tail wheel Luscombe 8F, claiming improvements over the original version.
