This AD is obsolete as the flight manual must furnish all airspeed limitations necessary for the safe operation of the aircraft. |\n\n![](image.001.png)\n\nDavid Punshon  \nDelegate of the Civil Aviation Safety Authority\n\n18 October 2007","sortOrder":0},{"sectionNumber":"AD/GENERAL/18 Amdt 1","sectionType":"part","heading":"AD/GENERAL/18 Amdt 1","content":"## AD/GENERAL/18 Amdt 1","sortOrder":1},{"sectionNumber":"Automatic Pilot LimitationPlacard - Inst","sectionType":"part","heading":"Automatic Pilot LimitationPlacard - Installation","content":"## Automatic Pilot Limitation  \nPlacard - Installation","sortOrder":2},{"sectionNumber":"13/2007","sectionType":"part","heading":"13/2007","content":"## 13/2007","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1828},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":true,"description":"This amendment eliminates the entire scope of the original Airworthiness Directive.

In those cases, owners had to install a physical placard (a warning sign) in the cockpit showing those limits. Modern rules now require flight manuals to include all necessary airspeed limits by default, making the separate placard requirement redundant.\n\n**Who is affected**\n\nThis affects aircraft owners and operators who were previously required to comply with the placard rule (AD/GENERAL/18). The cancellation takes effect on 20 December 2007.\n\n**Why it matters**\n\nThis removes an obsolete paperwork and hardware requirement, simplifying compliance for aircraft operators while maintaining safety standards through updated flight manual regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled","history":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled/history","analysis":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled/analysis","conflicts":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled/conflicts","importantCases":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled/important-cases","documents":"/api/acts/ad-general-18-amdt-1-automatic-pilot-limitation-placard-installation-cancelled/documents"}}
