(D) The substitute pilot or flight en-

gineer is in possession of all items re-
quired for duty. 

(E) The substitute pilot or flight en-

gineer is located in the passenger 
cabin. 

(F) The substitute pilot or flight en-

gineer is identified to the passengers. 

(G) The substitution of a pilot or 

flight engineer for a required flight at-
tendant does not interfere with the 
safe operation of the flight. 

(H) The airplane engines are shut 

down. 

(I) At least one floor-level exit re-

mains open to provide for passenger 
egress. 

(b) During passenger deplaning, on 

each airplane for which more than one 
flight attendant is required by § 121.391, 
the certificate holder may reduce the 
number of flight attendants required 
by that paragraph provided: 

(1) The airplane engines are shut 

down; 

(2) At least one floor level exit re-

mains open to provide for passenger 
egress; and 

(3) The number of flight attendants 

on board is at least half the number re-
quired by § 121.391, rounded down to the 
next lower number in the case of frac-
tions, but never fewer than one. 

(c) If only one flight attendant is on 

the airplane during passenger boarding 
or deplaning, that flight attendant 
must be located in accordance with the 
certificate holder’s FAA-approved op-
erating procedures. If more than one 
flight attendant is on the airplane dur-
ing passenger boarding or deplaning, 
the flight attendants must be evenly 
distributed throughout the airplane 
cabin, in the vicinity of the floor-level 
exits, to provide the most effective as-
sistance in the event of an emergency. 

(d) The time spent by any crew-

member conducting passenger boarding 
or deplaning duties is considered duty 
time.

possible incapacitation of individual 
crewmembers or their inability to 
reach the passenger cabin because of

each category of required crew-
