Summary

Description

English: The Lockheed 12A Electra Junior executive transport, as delivered from the factory, only had fins mounted at the tips of the horizontal tail. Langley added a center fin to improve the directional stability of its Lockheed 12A in June 1940. This Electra Junior was also equipped with wing de-icing using engine exhaust. The latter modification resulted in "NACA 97" becoming one of the first aircraft assigned to the newly-opened Ames Aeronautical Laboratory in California. The center fin was removed at the time the aircraft was sold in order to comply with the approved type certificate for the aircraft.
