Pt. 33, App. A

14 CFR Ch. I (1-1-19 Edition)

to document power and thrust characteristics.
(e) At the conclusion of the testing
required by paragraph (c) of this section, 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 accordance with the on-wing inspection recommendations and limits contained in
the Instructions for Continued Airworthiness submitted in compliance
with Section 33.4.
(3) Be completely disassembled and
inspected - 
(i) In accordance with the applicable
inspection recommendations and limits
contained in the Instructions for Continued Airworthiness submitted in
compliance with Section 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 identified 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 operational procedures before ETOPS eligibility is granted. The type and frequency of wear and distress that occurs
during the engine test must be consistent with the type and frequency of
wear and distress that would be expected to occur on ETOPS eligible engines.
(f) An alternative mission cycle endurance test that provides an equivalent demonstration of the unbalance
and vibration specified in paragraph (c)
of this section may be used when approved by the FAA.

(g) For an applicant using the simulated ETOPS mission cyclic endurance
test to comply with Section 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
Section 33.90(a). Following the inspection, the
ETOPS test must be resumed to complete the requirements of this section.

APPENDIX A TO PART 33 - INSTRUCTIONS
FOR CONTINUED AIRWORTHINESS
A33.1

GENERAL

(a) This appendix specifies requirements
for the preparation of Instructions for Continued Airworthiness as required by Section 33.4.
(b) The Instructions for Continued Airworthiness for each engine must include the
Instructions for Continued Airworthiness for
all engine parts. If Instructions for Continued 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 Instructions for Continued Airworthiness made
by the applicant or by the manufacturers of
engine parts will be distributed.
A33.2

FORMAT

(a) The Instructions for Continued Airworthiness 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.
A33.3

CONTENT

The contents of the manual or manuals
must be prepared in the English language.
The Instructions for Continued Airworthiness 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,
deinhibiting, acceptance checking, lifting,
and attaching accessories, with any necessary checks.
