The proposed production aircraft featured an extended span wing with leading edge slats removed to reduce structural complexity, weight and cost.

Other changes under consideration at the time of initial production were direction of undercarriage retraction and retention of the variable incidence tailplane.

The all-metal fail-safe semi-monocoque tubular fuselage was to have been pressurized and to accommodate a flight crew of two, 50–60 passengers, a single stewardess, a coat compartment, galley and toilet, as well as a pressurized baggage compartment aft of the main cabin.

The mainplanes were constructed as two-spar fail-safe structures from 2024-T4 light alloy supporting the engines, ailerons and hydraulically actuated single slotted flaps.

Pneumatic de-icing boots on the fin and rudder leading edges ensured ice free operation.
