This Directive was not based on a US Directive. This Directive and SB No. 350 required compliance in 1972 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-28/36","sectionType":"part","heading":"AD/PA-28/36","content":"## AD/PA-28/36","sortOrder":1},{"sectionNumber":"Stabilator Hinge Attaching Bolts - Inspe","sectionType":"part","heading":"Stabilator Hinge Attaching Bolts - Inspection","content":"## Stabilator Hinge Attaching Bolts - Inspection","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":1778},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument is a specific revocation notice that performs exactly its intended function of cancelling the previous airworthiness directive.

The rule is therefore obsolete and no longer needs to be enforced.\n\n**Who is affected:** Owners and operators of Piper PA-28 series aircraft no longer need to comply with this specific inspection requirement."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled","history":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled/history","analysis":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled/important-cases","documents":"/api/acts/ad-pa-28-36-stabilator-hinge-attaching-bolts-inspection-cancelled/documents"}}
