This Directive was not based on a US Directive. This Directive and SB No. 295 required compliance in 1969 so all affected aircraft would have been modified long ago. Hence, this AD is no longer required. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n19 May 2008","sortOrder":0},{"sectionNumber":"AD/PA-28/24","sectionType":"part","heading":"AD/PA-28/24","content":"## AD/PA-28/24","sortOrder":1},{"sectionNumber":"Control Wheel Retaining Pin - Modificati","sectionType":"part","heading":"Control Wheel Retaining Pin - Modification","content":"## Control Wheel Retaining Pin - Modification","sortOrder":2},{"sectionNumber":"7/2008","sectionType":"part","heading":"7/2008","content":"## 7/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1933},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument performs exactly the narrow function described in its title—formally revoking an obsolete airworthiness directive.

The original directive required a one-time safety modification to the control wheel retaining pin on Piper PA-28 aeroplanes (a fix to prevent the steering yoke from coming loose).\n\n**Why it matters:** Because the original modification was mandated back in 1969, the aviation safety authority assumes every affected plane has been fixed by now. This cancellation cleans up the rulebook so aircraft owners and mechanics don't need to track an obsolete requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled","history":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled/history","analysis":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-28-24-control-wheel-retaining-pin-modification-cancelled/documents"}}
