If you had not completed this inspection by the 1995 deadline, you no longer need to do so."}},"importantCases":[],"_links":{"self":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled","history":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled/history","analysis":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled/analysis","conflicts":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled/conflicts","importantCases":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled/important-cases","documents":"/api/acts/ad-r22-39-upper-clutch-actuator-bearing-cancelled/documents"}}
