This sticker currently displays the limitation: *\"3200 RPM Minimum below 400 feet above terrain\"*.\n\n**Why it matters:** This removes an outdated operating restriction. The reference to Hughes Service Instruction No. N-134 indicates the manufacturer determined this RPM limitation was no longer necessary or appropriate.\n\n**When to comply:** The modification must be completed within **100 hours of flight time** accumulated after 31 July 1977. Note that \"time in service\" refers to actual flying hours, not calendar dates."}},"importantCases":[],"_links":{"self":"/api/acts/ad-hu-269-59-cockpit-placard-removal","history":"/api/acts/ad-hu-269-59-cockpit-placard-removal/history","analysis":"/api/acts/ad-hu-269-59-cockpit-placard-removal/analysis","conflicts":"/api/acts/ad-hu-269-59-cockpit-placard-removal/conflicts","importantCases":"/api/acts/ad-hu-269-59-cockpit-placard-removal/important-cases","documents":"/api/acts/ad-hu-269-59-cockpit-placard-removal/documents"}}
