I checked my copy of ANC-18, "Design of Wooden Aircraft Structures" and mechanical properties of aspen are not listed. That means that when the book was published in 1951, aspen was not considered to be an aircraft grade of wood. In that reference, there are about 40 different types of wood where mechanical data is listed.
