China Civil Aviation Technical Standard Order
- 1 -
This China Civil Aviation Technical Standard Order (CTSO) is issued according to
Part 37 of the China Civil Aviation Regulations (CCAR-37). Each CTSO is a criterion
which the concerned aeronautical materials, parts or appliances used on civil aircraft must
comply with when it is presented for airworthiness certification.
Cargo Restraint Strap Assemblies
1. Purpose.
This China Civil Aviation Technical Standard Order (CTSO) is for
manufacturers applying for cargo restraint strap assemblies CTSO
authorization (CTSOA). This CTSO prescribes the minimum
performance standards(MPS) that cargo restraint strap assemblies must
first meet for approval and identification with the applicable CTSO
marking.
2. Applicability.
This CTSO affects new application submitted after its effective date.
Major design changes to article approved under this CTSO will require a
new authorization in accordance with section 21.310 of CCAR-21R3.
3. Requirements.
New models of cargo restraint strap assemblies identified and

manufactured on or after the effective date of this CTSO must meet the
MPS qualification and documentation requirements in SAE International
(SAE) Aerospace Standard (AS) 5385C, Cargo Restraint Straps ?C Design
Criteria and Testing Methods, dated January 2007, as modified by
Appendix 1 of this CTSO.
a. Functionality. This CTSO’s standards apply to equipment intended
to be used to restrain cargo on board civil transport aircraft during flight.
b. Functional Qualification. Demonstrate the required performance
under the test conditions in SAE AS5385C as modified by Appendix 1 of
this CTSO.
c. Environmental Qualification. A cargo restraint strap assembly
must meet the minimum performance requirements of this CTSO at any
time during its service life.
(1) Determine when environmental degradation due to aging,
ultra-violet (UV) exposure, weathering, etc., for any materials used in the
construction of cargo restraint strap assemblies is unacceptable.
(2) For textile performance, see SAE Aerospace Information Report
(AIR) 1490B, Environmental Degradation of Textiles, dated December
2007, for available data when exposed to environmental factors.
Determine when the environmental effects of degradation on cargo
restraint strap assemblies commensurate with the expected storage and
service life become unacceptable for the minimum performance
