The Lockheed 14 Super Electra was a twin-engine passenger aircraft made in the USA .
history
The first flight of the machine took place on July 29, 1937. Lockheed wanted the Super Electra to compete with the Douglas DC-3 , but underestimated the rapidly developing air traffic. Although the aircraft turned out well (good flight performance, range and controllability; very advanced design with integral wing tanks, controllable pitch propellers and Fowler flaps ), it was ultimately too small for its intended purpose. A capacity of 14 passengers (versus 28 for the DC-3 ) was a major economic disadvantage; the entire Electra series became a financial disaster for Lockheed.
Most of the copies have been exported. In Japan, the model was built under license as the Kawasaki Ki-56 . The Lockheed Hudson light bomber and reconnaissance aircraft was based on the Lockheed 14 .
Incidents
- On July 14, 1952, a Lockheed 14H Super Electra of the Airtaco (registration number SE-BTN ) crashed during the climb from Stockholm / Bromma airport due to the switching to an almost empty fuel tank. Four of the six inmates died. The machine was on a newspaper flight to Jönköping.
