    (b) Occupants in addition to those authorized under paragraph (a) of 
this section may be carried as follows:
    (1) For each additional floor-level exit at least 24 inches wide by 
48 inches high, with an unobstructed 20-inch-wide access aisleway 
between the exit and the main passenger aisle, 12 additional occupants.
    (2) For each additional window exit located over a wing that meets 
the requirements of the airworthiness standards under which the airplane 
was type certificated or that is large enough to inscribe an ellipse 
19x26 inches, eight additional occupants.
    (3) For each additional window exit that is not located over a wing 
but that otherwise complies with paragraph (b)(2) of this section, five 
additional occupants.
    (4) For each airplane having a ratio (as computed from the table in 
paragraph (a) of this section) of maximum number of occupants to number 
of exits greater than 14:1, and for each airplane that does not have at 
least one full-size, door-type exit in the side of the fuselage in the 
rear part of the cabin, the first additional exit must be a floor-level 
exit that complies with paragraph (b)(1) of this section and must be 
located in the rear part of the cabin on the opposite side of the 
fuselage from the main entrance door. However, no person may operate an 
airplane under this section carrying more than 115 occupants unless 
there is such an exit on each side of the fuselage in the rear part of 
the cabin.
    (c) No person may eliminate any approved exit except in accordance 
with the following:
    (1) The previously authorized maximum number of occupants must be 
reduced by the same number of additional occupants authorized for that 
exit under this section.
    (2) Exits must be eliminated in accordance with the following 
priority schedule: First, non-over-wing window exits; second, over-wing 
window exits; third, floor-level exits located in the forward part of 
the cabin; and fourth, floor-level exits located in the rear of the 
cabin.
    (3) At least one exit must be retained on each side of the fuselage 
regardless of the number of occupants.
    (4) No person may remove any exit that would result in a ratio of 
maximum number of occupants to approved exits greater than 14:1.
    (d) This section does not relieve any person operating under part 
121 of this chapter from complying with Sec. 121.291.
