FHA says 5/8" rock but this panel is only 3/8"

How do you make a hatch out of same 5/8" rock???

WTF actually works for this inspection?

AI says:

"Attic access cover: If there is an access panel to the attic from the garage, it must be constructed of the same fire-rated material as the ceiling. The cover must be permanently installed and have latching hardware that keeps it closed."

Is AI just dumb and what the FHA wants to see is a metal hatch?
