(a) As a carrier, you must ensure that there is priority space (i.e., a closet, or a row of seats where a wheelchair may be strapped using a strap kit that complies with applicable Federal Aviation Administration or applicable foreign government regulations on the stowage of cargo in the cabin compartment) in the cabin of sufficient size to stow at least one typical adult-sized folding, collapsible, or break-down manual passenger wheelchair, the dimensions of which are 13 inches by 36 inches by 42 inches or less without having to remove the wheels or otherwise disassemble it. This section applies to any aircraft with 100 or more passenger seats and this space must be other than the overhead compartments and under-seat spaces routinely used for passengers' carry-on items.
