The Aero Commander 100, various models of which were known as the Darter Commander and Lark Commander was an American light aircraft produced from 1960 until 1971.  It was a high-wing monoplane of conventional design, equipped with fixed tricycle undercarriage.


The aircraft was originally designed by 
Volaircraft, first flying in 1960. The firm marketed the original three-seat version as the Volaire 1035 and a four-seat version with a more powerful engine as the Volaire 1050 before North American Rockwell purchased all rights to the design on July 12, 1965, for production by its Aero Commander division. Production of the Darter Commander version continued until 1969 and of the revised Lark Commander until 1971 (by which time, Rockwell had dropped the Aero Commander brand name).
