Inertial subsystem warnings and coupling data unit failure indicators: Apollo 16 mission
Abstract
The indicated failures of the inertial coupling unit were investigated. The coupling data unit assembly failure detection circuits and the diagnostic tests are described. It is concluded that conductive contamination in a zener diode in the failure-detect circuit of the coupling data unit assembly most likely caused the problem.
