本文件已于2011年9月被宣布“取消”，并被as 6554取代。通过这一行动，本文件仍将列在航空航天标准索引的数字部分，并指出其已被AS 6554取代。本SAE航空航天推荐规程（ARP）旨在标准化与符合AS5385C要求的经批准系紧带一起使用的“货物挡块”货物系紧附件的基本设计、性能和测试要求。由于缺乏商定的行业标准，导致其运行能力存在不确定性，因此建议指定建议的设计、最低性能和测试要求。

This document has been declared "CANCELLED" as of September 2011 and has been superseded by AS 6554. By this action, this document will remain listed in the Numercial Section of the Aerospace Standards Index noting that it is superseded by AS 6554.The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize the basic design, performance and testing requirements for "Cargo Stoppers" cargo tie-down accessories to be used in conjunction with approved tie-down straps meeting AS5385C requirements.The lack of an agreed industry standard results in uncertainties about their operational capabilities, so that it was deemed advisable to specify recommended design, minimum performance and testing requirements.
