plane unless there is installed in each 
lavatory a sign or placard that reads: 
‘‘Federal law provides for a penalty of 
up to $2,000 for tampering with the 
smoke detector installed in this lava-
tory.’’ These signs or placards need not 
meet the requirements of paragraph (a) 
of this section. 

(f) Each passenger required by 

§ 121.311(b) to occupy a seat or berth 
shall fasten his or her safety belt about 
him or her and keep it fastened while

Smoking’’ sign is lighted or while ‘‘No 
Smoking’’ placards are posted, except 
as follows: 

(1) 

Supplemental operations. 

The pilot 

in command of an airplane engaged in 
a supplemental operation may author-
ize smoking on the flight deck (if it is 
physically separated from any pas-
senger compartment), but not in any of 
the following situations: 

(i) During airplane movement on the 

surface or during takeoff or landing; 

(ii) During scheduled passenger-car-

rying public charter operations con-
ducted under part 380 of this title; or

Except during airplane move-

ment on the surface or during takeoff 
or landing, a pilot in command of an 
airplane engaged in a domestic oper-
ation may authorize smoking on the

from the passenger compartment) if— 

(i) Smoking on the flight deck is not 

otherwise prohibited by part 252 of this 
title; 

(ii) The flight is conducted entirely 

within the same State of the United 
States (a flight from one place in Ha-
waii to another place in Hawaii 
through the airspace over a place out-
side of Hawaii is not entirely within 
the same State); and 

(iii) The airplane is either not tur-

bojet-powered or the airplane is not ca-
pable of carrying at least 30 passengers. 

(h) No person may smoke in any air-

plane lavatory. 

(i) No person may tamper with, dis-

able, or destroy any smoke detector in-

be turned on during any movement on 
the surface, for each takeoff, for each 
landing, and at any other time consid-
ered necessary by the pilot in com-
mand. 

(k) Each passenger shall comply with 

instructions given him or her by a 
crewmember regarding compliance 
with paragraphs (f), (g), (h), and (l) of 
this section. 

(l) A certificate holder may operate a 

nontransport category airplane type 
certificated after December 31, 1964, 
that is manufactured before December 
20, 1997, if it is equipped with at least

son seated in the cabin that states 
‘‘Fasten Seat Belt,’’ and if, during any 
movement on the surface, for each 
takeoff, for each landing, and at any 
other time considered necessary by the 
pilot in command, a crewmember oral-
ly instructs the passengers to fasten 
their seat belts.
