This Directive was not based on a US Directive. Compliance was required within 100 hours after February 1978 so the Directive is no longer required. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n22 May 2008","sortOrder":0},{"sectionNumber":"AD/PA-28/69","sectionType":"part","heading":"AD/PA-28/69","content":"## AD/PA-28/69","sortOrder":1},{"sectionNumber":"Engine Cowling - Drain Hole Provision","sectionType":"part","heading":"Engine Cowling - Drain Hole Provision","content":"## Engine Cowling - Drain Hole Provision","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":1694},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument serves a single, narrow purpose: to revoke a previous airworthiness directive.

This was a one-off modification to let moisture escape and prevent engine damage.\n\n**Why it matters:**\n- The original rule required owners to make this modification within 100 hours of flying time after February 1978\n- That deadline passed decades ago, meaning the rule has been effectively dead for years—anyone who needed to comply already has, or the aircraft has been retired\n- This cancellation simply cleans up the rulebook so operators don’t have to check an obsolete requirement\n\n**Who is affected:**\n- Owners and operators of Piper PA-28 aircraft registered in Australia (though practically speaking, this just tidies paperwork rather than changing what they must do today)"}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled","history":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled/history","analysis":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled/important-cases","documents":"/api/acts/ad-pa-28-69-engine-cowling-drain-hole-provision-cancelled/documents"}}
