This is because the original bearing is too weak to handle pressure caused by hydraulic fluid expanding when it heats up.\n\n**When:**\nThe replacement must be completed within 100 hours of flight time after 31 July 1979.\n\n**Why it matters:**\nIf the bearing fails due to thermal stress, it could cause nose landing gear failure, potentially leading to a dangerous situation during takeoff or landing."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement","history":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement/history","analysis":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement/analysis","conflicts":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement/conflicts","importantCases":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement/important-cases","documents":"/api/acts/ad-pa-32-62-nose-gear-actuator-rod-end-bearing-replacement/documents"}}
