Previously, mechanics had to regularly check the shock absorber rods for wear. Now, operators no longer need to perform this specific inspection at set intervals, saving time and maintenance costs while relying on standard maintenance practices instead."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled","history":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled/history","analysis":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled/analysis","conflicts":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled/conflicts","importantCases":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled/important-cases","documents":"/api/acts/ad-beech-23-13-main-and-nose-landing-gear-shock-absorber-cancelled/documents"}}
