Standardized technical measurements cross-referenced against original civil aeronautics type certificate data sheets and military maintenance manuals.
Powerplant Parameters
Aerodynamic Geometry
Structural Capacities
Twin Pratt and Whitney R-1830-S1C3G 14-cylinder twin-row radial engines delivering 1,200 takeoff horsepower each at 2,700 RPM with three-blade Hamilton Standard hydromatic propellers.
All-metal cantilever low-wing configuration with a 95-foot wingspan, 987 square feet of reference wing area, and a 64-foot 8-inch total fuselage length.
Maximum gross takeoff weight of 25,200 pounds, empty weight of 16,865 pounds, and an internal fuel capacity of 822 US gallons across four wing tanks.
Airframe Variant Lineage
Civil Aeronautics Administration certification records establish the DST and DC-3 series baseline under specification A-669. Structural revisions accommodated passenger sleeper berths, high-density airline seating, and reinforced cargo decks across 16,079 total airframe serials.
Wing chord tapers from 198 inches at the root to 64 inches at the wingtip fairing, maintaining a five-degree dihedral angle across outer panels. Center-section spars carry landing gear retraction assemblies and nacelle support bulkheads directly.
Verified Flight Envelope Limits
Official flight manual restrictions establish a 23,200-foot service ceiling, a 207-knot never-exceed velocity, and a clean-configuration stall speed of 59 knots at maximum landing weight.
