Model 520 (6A1)

The 520 was first certified on January 31, 1952. It was very similar to L-3805 except for an increase in gross weight from 4600 pounds to 5500 pounds and the engines were changed to Lycoming GO 435-C2B (260HP). In 1954 the gross weight was increased to 5700 pounds with some structural changes made.

Early in May 1951 due to the inherent stability, and great ease of control under single engine operation of the Aero Commander aircraft the company decided to perform a daring feat never successfully accomplished by a twin-engine aircraft. On May 8th, 1951, a Aero Commander prototype aircraft fully loaded to max gross weight, the LH propeller removed and stowed in the cabin took-off from Oklahoma City using the right hand engine only and flew non-stop to Washington DC to the accolades of the aviation world.
