自2011年1月起，本文件已被宣布“取消”。通过这一行动，本文件将保留在航空航天标准索引的数字部分。该文件尚未保存。该文件的主要目的是为轮半设计静态密封压盖和o形圈提供说明。现代车轮静密封压盖和o形圈的设计必须考虑车轮尺寸、用途、环境和类型（例如可拆卸法兰）。设计取决于这些因素，因此不同应用的设计会有所不同，而不是666规定的所有应用都有一种设计。

This document has been declared "CANCELLED" as of January 2011. By this action, this document will remain listed in the Numercial Section of the Aerospace Standards Index.This document has not been maintained. The document’s primary purpose was to provide instructions for designing a static seal gland and o-ring for the wheel halves. Modern wheel static seal gland & o-ring design must take into account the wheel size, use, environment and type (for example demountable flange). The designs depend on these factors such that the designs will vary for different applications as opposed to having one design for all applications as AS 666 specifies.
