(a) Except as provided in paragraph 

(a)(1) of this section, each certificate 
holder must conduct an actual dem-
onstration of emergency evacuation 
procedures in accordance with para-
graph (a) of appendix D to this part to

senger-carrying operations allows the 
evacuation of the full capacity, includ-
ing crewmembers, in 90 seconds or less. 

(1) An actual demonstration need not 

be conducted if that airplane type and 
model has been shown to be in compli-
ance with this paragraph in effect on or

on or after that date. 

(b) Each certificate holder con-

ducting operations with airplanes with 
a seating capacity of more than 44 pas-
sengers must conduct a partial dem-

this section, each certificate holder 
must: 

(1) Demonstrate the effectiveness of 

its crewmember emergency training 
and evacuation procedures by con-
ducting a demonstration, not requiring 
passengers and observed by the Admin-
istrator, in which the flight attendants 
for that type and model of airplane, 
using that operator’s line operating 
procedures, open 50 percent of the re-
quired floor-level emergency exits and 
50 percent of the required non-floor- 
level emergency exits whose opening 
by a flight attendant is defined as an 
emergency evacuation duty under 
§ 121.397, and deploy 50 percent of the 
exit slides. The exits and slides will be 
selected by the administrator and must 
be ready for use within 15 seconds;

FAA-approved training program for the 
type and model of airplane, and have 
passed a written or practical examina-
tion on the emergency equipment and 
procedures; and 

(4) Apply for and obtain approval 

from the responsible Flight Standards 
office before commencing operations

in accordance with paragraph (b) of ap-
pendix D to this part, that it has the 
ability to efficiently carry out its 
ditching procedures. For certificate 
holders subject to § 121.2(a)(1), this 
paragraph applies only when a new 
type or model airplane is introduced
