Question

What was the first airplane that had metal as it's skin as opposed to fabric?

Answer 1

In the spring of 1920, American pilot John M. Larsen began demonstrating an imported Junkers all-metal passenger plane designated the JL-6. This German aircraft created much excitement within the American aviation community. The U.S. Postal Service bought six of the aircraft.

The enthusiasm over the JL-6 caused many aviation leaders to call for the development of all-metal aircraft. The National Advisory Committee for Aeronautics (NACA) declared in its 1920 Annual Report that metal was superior to wood because "metal does not splinter, is more homogeneous, and the properties of the material are much better known and can be relied upon. Metal also can be produced in large quantities, and it is felt that in the future all large airplanes must necessarily be constructed of metal."

NACA immediately began research into all-metal construction, and the U.S. Navy developed duralumin fabrication techniques at the Naval Aircraft Factory. In 1924, the first all-metal commercial airplane, called the Pullman, was produced by William Stout. Glenn Martin Aircraft also developed all-metal aircraft for the U.S. Navy in 1923, where the only wooden structure was the engine mount.

Answer 2

Probably the Junkers JL 6.
