There are two main airworthiness categories: Standard and Special.

Standard airworthiness aircraft are proven to meet certain FAA standards, and
The FAA waiver usually demands that these planes receive professional-type
maintenance similar to that of standard airworthiness aircraft (e.g., the L-39
instructor won't be allowed the maintain the plane himself unless he has an A&P
license).
