The FAA approves ETOPS in accordance 

with the requirements and limitations in 
this appendix. 

Section I. 

ETOPS Approvals: Airplanes with 

Two engines. 

(a) 

Propulsion system reliability for ETOPS. 

(1) Before the FAA grants ETOPS oper-
ational approval, the operator must be able 
to demonstrate the ability to achieve and 
maintain the level of propulsion system reli-
ability, if any, that is required by § 21.4(b)(2) 
of this chapter for the ETOPS-approved air-
plane-engine combination to be used. 

(2) Following ETOPS operational approval, 

the operator must monitor the propulsion 
system reliability for the airplane-engine 
combination used in ETOPS, and take action 
as required by § 121.374(i) for the specified 
IFSD rates. 

(b) 

75 Minutes ETOPS

—(1) 

Caribbean/Western 

Atlantic Area. 

The FAA grants approvals to 

conduct 

ETOPS with maximum diversion times up 

to 75 minutes on Western Atlantic/Caribbean 
area routes as follows: 

(i) The FAA reviews the airplane-engine 

combination to ensure the absence of factors 
that could prevent safe operations. The air-
plane-engine combination need not be type- 
design-approved for ETOPS; however, it 
must have sufficient favorable experience to 
demonstrate to the Administrator a level of 
reliability appropriate for 75-minute ETOPS. 

(ii) The certificate holder must comply 

with the requirements of § 121.633 for time- 
limited system planning. 

(iii) The certificate holder must operate in 

accordance with the ETOPS authority as 
contained in its operations specifications. 

(iv) The certificate holder must comply 

with the maintenance program requirements 
of § 121.374, except that a pre-departure serv-
ice check before departure of the return 
flight is not required. 

(2) 

Other Areas. 

The FAA grants approvals 

to conduct ETOPS with maximum diversion 
times up to 75 minutes on other than West-
ern Atlantic/Caribbean area routes as fol-
lows: 

(i) The FAA reviews the airplane-engine 

combination to ensure the absence of factors 
that could prevent safe operations. The air-
plane-engine combination need not be type- 
design-approved for ETOPS; however, it 
must have sufficient favorable experience to 
demonstrate to the Administrator a level of 
reliability appropriate for 75-minute ETOPS. 

(ii) The certificate holder must comply 

with the requirements of § 121.633 for time- 
limited system planning. 

(iii) The certificate holder must operate in 

accordance with the ETOPS authority as 
contained in its operations specifications. 

(iv) The certificate holder must comply 

with the maintenance program requirements 
of § 121.374. 

(v) The certificate holder must comply 

with the MEL in its operations specifications 
for 120-minute ETOPS. 

(c) 

90-minutes ETOPS (Micronesia). 

The FAA 

grants approvals to conduct ETOPS with 
maximum diversion times up to 90 minutes 
on Micronesian area routes as follows: 

(1) The airplane-engine combination must 

be type-design approved for ETOPS of at 
least 120-minutes. 

(2) The certificate holder must operate in 

accordance with the ETOPS authority as 
contained in its operations specifications. 

(3) The certificate holder must comply 

with the maintenance program requirements 
of § 121.374, except that a pre-departure serv-
ice check before departure of the return 
flight is not required. 

(4) The certificate holder must comply 

with the MEL requirements in its operations 
specifications for 120-minute ETOPS. 

(d) 

120-minute ETOPS. 

The FAA grants ap-

provals to conduct ETOPS with maximum 
diversion times up to 120 minutes as follows: 

(1) The airplane-engine combination must 

be type-design-approved for ETOPS of at 
least 120 minutes. 

(2) The certificate holder must operate in 

accordance with the ETOPS authority as 
contained in its operations specifications. 

(3) The certificate holder must comply 

with the maintenance program requirements 
of § 121.374. 

(4) The certificate holder must comply 

with the MEL requirements for 120-minute 
ETOPS. 

(e) 

138-Minute ETOPS. 

The FAA grants ap-

proval to conduct ETOPS with maximum di-
version times up to 138 minutes as follows: 

(1) 

Operators with 120-minute ETOPS ap-

proval. 

The FAA grants 138-minute ETOPS 

approval as an extension of an existing 120- 
minute ETOPS approval as follows: 

(i) The authority may be exercised only for 

specific flights for which the 120-minute di-
version time must be exceeded. 

(ii) For these flight-by-flight exceptions, 

the airplane-engine combination must be 
type-design-approved for ETOPS up to at 
least 120 minutes. The capability of the air-
plane’s time-limited systems may not be less 
than 138 minutes calculated in accordance 
with § 121.633. 

(iii) The certificate holder must operate in 

accordance with the ETOPS authority as 
contained in its operations specifications. 

(iv) The certificate holder must comply 

with the maintenance program requirements 
of § 121.374. 

(v) The certificate holder must comply 

with minimum equipment list (MEL) re-
quirements in its operations specifications 
for ‘‘beyond 120 minutes ETOPS’’. Operators 
without a ‘‘beyond 120-minute ETOPS’’ MEL
