CTSO & CTSOA AND GUIDELINES
o
A Chinese Technical Standard Order (CTSO) is a minimum performance standard
issued by CAAC for specified material, parts, or appliances used on civil aircraft, as
defined in CCAR-21-R3. And each CTSO is considered as part of CCAR-37.
o
A CTSO Authorization (CTSOA) is a CAAC design and production approval issued to a
manufacturer of an article that has been found to meet a specific CTSO. CTSOA does
not mean installation approval.
o
CAAC issued the following Administration Procedures (APs) which provide the guidance
on design and production certification procedure :
 AP-21-06-R3 Certification Procedure for Civil Aviation Material, Part and Onboard Equipment
 AP-21-04-R3 Certification and Surveillance Procedure of Production Approval

CONCEPT OF IMA
IMA is a shared set of flexible, reusable, and interoperable hardware and software resources that, when
integrated, form a platform that provides services, designed and verified to a defined set of safety and
performance requirements, to host applications performing aircraft functions.[Section 1.2, DO-297]

•
DO-297 takes the concept of “incremental acceptance”, which divides the acceptance into six
“certification tasks” in the certification program.
•
FAA AC 20-170 recognizes DO-297 as an acceptable means of compliance and provides explanations
for IMA certification and approval in according with DO-297 as well as TSO-C153.
•
CAAC issued MD-AA-2011-003 and Issue Paper EE-9 to recognize AC 20-170 and DO-297 as
acceptable guidance and means of compliance in C919 program.
•
Proposed CTSO-C153 is documented by reference to FAA TSO-C153, and it’s expected that CAAC
will issue it in first half year of 2016.

TSO-C153 VS FUNCTIONAL TSO
FAA AC 20-170 specifies two types of TSO authorized components in IMA system:
 TSO-C153
•
TSO-C153 applies for
 Functional TSOs
•
Functional TSOs are ones with the defined
aircraft functionality, which are traditionally
implemented by separate LRUs.
•
Not normally used except in the context of
IMA systems.
 Generic hardware modules
 Cabinets/racks that host hardware modules
 Software that enables electronic part
marking and/or future loading of functional
software

MINIMUM PERFORMANCE STANDARD (MPS)
 CTSO-C153 does not call out any industry standards as well as FAA TSO-C153.
 To obtain CTSO-C153 authorization, applicants must :
 Develop and submit an MPS for each individual hardware element in according to
the criteria and guidance in Appendix A.
 Demonstrate the compliance to the requirements specified in the MPS.
 In the MPS, applicants should specify :
 All minimum performance requirements stated in measurable terms. [Table 1,
Appendix 1, CTSO-C153 ]
 Requirements of environmental qualification tests per RTCA/DO-160D (change 2)
[Table 1, Appendix 1, CTSO-C153]
 Test procedure to verify that the element performs its intended functions both over
standard conditions and environmental condition.
 When to obtain functional TSO authorization with CTSO-C153 authorization together, the
functions which assure that the hardware element correctly executes the functional software
should be addressed in the MPS.
16
4/27/2016
TEST CONFIGURATION
 Test configuration should be specified in MPS or the separate test procedure
documents.
 CTSO-C153 provides the minimum test configuration requirements of the
hardware elements.
o For cabinet or rack, the test
configuration should include (as a
minimum):


Cabinet or rack with all integrated cooling
and power supplies
Power supply modules (if not integrated
into the cabinet or rack)
o For a module to be tested, the test
configuration should include (as a
minimum):

Cabinet or rack

Power supply modules (if required by the
module to function)

Processing modules (if required by the
module to function)

Processing modules

Data communication modules (if not
integrated into the cabinet or rack)

Data communication (if required by the
module to function)

Appropriate covers or position fillers
installed in all unused positions of
cabinet/rack (if applicable).

Appropriate covers or position fillers
installed in all unused positions of
cabinet/rack (if applicable).
17
4/27/2016
TEST CONFIGURATION
 WHEN to use the special purpose test software or functional software for
demonstrating the operation of the hardware element functions,
APPLICANTS must verify, validate, and control the configuration of the
software to ensure the validity of the testing.
 WHEN to apply CTSO-C153 authorization for several separate IMA modules in
the meantime,
APPLICANTS may elect the approach of testing the related modules
together installed in a cabinet or rack.
18
4/27/2016
ENVIRONMENTAL QUALIFICATION TEST (EQT)
 Applicants should perform the EQT per the environmental conditions specified in the
MPS.
 Certain D0-160 EQT items are excluded from CTSO-C153 as specified in Table 2 of
Appendix 1, as they can only be appropriately performed WITH:
 The configured IMA system specified for the applicable aircraft under TC/ STC.
 The functional software(s) installed and operating.
 Per Appendix A of AC 20-170, applicants may elect the applicable environmental
qualification tests to meet the requirements of the customers and expected installation
environment.
 Applicants may use Category X on any environmental test procedure to indicate that the
compliance with the MPS has not been demonstrated under CTSO-C153 tests.

MARKING LABEL
CTSO MARKING DOES NOT MEAN
CTSO MARKING MEANS
•
•
The article deign meets the CAAC CTSO
for which it is marked,
The article conforms to the approved
design since it was produced under an
approved quality systems.
General Requirement for CTSO articles:
[CCAR §21.312]
• Manufacturer’s name and address
• Article’s name
• Module Number/Part number
• Serious number(or manufacture date)
• CTSO number
•
•
The article is approved for installation or,
The article’s design meets airworthiness
regulations for a particular product
(aircraft, engine or propeller).
Additional consideration for C153 Articles:
[CTSO-C153]
• “CTSO authorization for cabinet (rack)
only”
• Separate part numbers for hardware and
software
• Electronic TSO nameplate

SUMMARY
 RTCA/DO-297 and FAA AC 20-170 provide the means of compliance of IMA
certification and approval, and also provide the guidance on how to use the
TSO certified components in IMA certification approval, which are followed in
CAAC certification program.
 Applicants of CTSOA should consider the scope and requirements for CTSOC153 and Functional TSO as well as non-TSO functions.
 Applicants for CTSO-C153 authorization should develop and submit MPS for
each individual hardware element, which should meet the specific
requirements of CTSO-C153 and AC 20-170 (e.g. test configuration, DO-160
test items, marking label.)
