14 CFR Ch. I (1–1–19 Edition) 

Pt. 33, App. A 

to document power and thrust charac-
teristics. 

(e) At the conclusion of the testing 

required by paragraph (c) of this sec-
tion, the engine must: 

(1) Be subjected to a calibration test 

at sea-level conditions. Any change in 
power or thrust characteristics must 
be within approved limits. 

(2) Be visually inspected in accord-

ance with the on-wing inspection rec-
ommendations and limits contained in 
the Instructions for Continued Air-
worthiness submitted in compliance 
with § 33.4. 

(3) Be completely disassembled and 

inspected— 

(i) In accordance with the applicable 

inspection recommendations and limits 
contained in the Instructions for Con-
tinued Airworthiness submitted in 
compliance with § 33.4; 

(ii) With consideration of the causes 

of IFSD, loss of thrust control, or other 
power loss identified by paragraph (b) 
of this section; and 

(iii) In a manner to identify wear or 

distress conditions that could result in 
an IFSD, loss of thrust control, or 
other power loss not specifically iden-
tified by paragraph (b) of this section 
or addressed within the Instructions 
for Continued Airworthiness. 

(4) Not show wear or distress to the 

extent that could result in an IFSD, 
loss of thrust control, or other power 
loss within a period of operation before 
the component, assembly, or system 
would likely have been inspected or 
functionally tested for integrity while 
in service. Such wear or distress must 
have corrective action implemented 
through a design change, a change to 
maintenance instructions, or oper-
ational procedures before ETOPS eligi-
bility is granted. The type and fre-
quency of wear and distress that occurs 
during the engine test must be con-
sistent with the type and frequency of 
wear and distress that would be ex-
pected to occur on ETOPS eligible en-
gines. 

(f) An alternative mission cycle en-

durance test that provides an equiva-
lent demonstration of the unbalance 
and vibration specified in paragraph (c) 
of this section may be used when ap-
proved by the FAA. 

(g) For an applicant using the simu-

lated ETOPS mission cyclic endurance 
test to comply with § 33.90, the test 
may be interrupted so that the engine 
may be inspected by an on-wing or 
other method, using criteria acceptable 
to the FAA, after completion of the 
test cycles required to comply with 
§ 33.90(a). Following the inspection, the 
ETOPS test must be resumed to com-
plete the requirements of this section.

GENERAL

 

(a) This appendix specifies requirements 

for the preparation of Instructions for Con-
tinued Airworthiness as required by § 33.4. 

(b) The Instructions for Continued Air-

worthiness for each engine must include the 
Instructions for Continued Airworthiness for 
all engine parts. If Instructions for Contin-
ued Airworthiness are not supplied by the 
engine part manufacturer for an engine part, 
the Instructions for Continued Airworthiness 
for the engine must include the information 
essential to the continued airworthiness of 
the engine. 

(c) The applicant must submit to the FAA 

a program to show how changes to the In-
structions for Continued Airworthiness made 
by the applicant or by the manufacturers of 
engine parts will be distributed.

33.2

FORMAT

 

(a) The Instructions for Continued Air-

worthiness must be in the form of a manual 
or manuals as appropriate for the quantity 
of data to be provided. 

(b) The format of the manual or manuals 

must provide for a practical arrangement.

33.3

CONTENT

 

The contents of the manual or manuals 

must be prepared in the English language. 
The Instructions for Continued Airworthi-
ness must contain the following manuals or 
sections, as appropriate, and information: 

(a) 

Engine Maintenance Manual or Section. 

(1) Introduction information that includes an 
explanation of the engine’s features and data 
to the extent necessary for maintenance or 
preventive maintenance. 

(2) A detailed description of the engine and 

its components, systems, and installations. 

(3) Installation instructions, including 

proper procedures for uncrating,
