adequate space for the user to immediately 
escape a hazardous cooktop condition. 

(i) A means to shut off power to the

(2) A number equal to the number of origi-

nally type certificated exit pairs, regardless 
of whether the exits are deactivated for the

(b) Extinguishers must be evenly distrib-

uted throughout the cabin. These extin-
guishers are in addition to those required by 
paragraph 14 of this SFAR, unless it can be
