- EAA is actively reviewing the draft
of the FAA's amateur-built and ultralight flight testing handbook, known as Advisory Circular 90-89
. The handbook, developed with substantial EAA input, was issued in 1995. This will be the first revision.
Because the handbook has been untouched for nearly two decades, it's outdated in several major areas. For example, there are no references to light-sport aircraft (which was not yet a legal definition for aircraft in 1995), while there are references to "fat ultralights" (which no longer exist). In addition to content updates and formatting changes to enhance readability, the FAA is working to modernize the language to make the document compliant with the Plain Writing Act.
Perhaps the most noticeable change to the original handbook has nothing to do with content: The format for the current draft version is single-column, while advisory circulars from the mid-1990s were two-column.
EAA staff will work with the EAA Homebuilt Advisory Council to review the handbook for clarity, accuracy, and possible areas where information could be expanded or added. After the review, EAA will submit formal comments to the FAA.
