3.5.4.6
Interchangeability - Gyros and accelerometers shall
be replaceable without major disassembly of the gimbal structure. The
slip rings shall be united with the synchros or torquers or both to
form an easily replaced assembly. The Gyroscope Assembly shall be such
that it can be removed from its mount and replaced with another unit
without making any alignment measurements.
