Rationale: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.
