The original directive (AD/PA-31/95) forced owners of Piper PA-31 aircraft to inspect and modify a tail control part (the *elevator bellcrank assembly*)—a one-off fix that had to be done within 100 flying hours after December 1980.\n\n**Why now?** That deadline passed nearly three decades ago, so every affected aircraft was fixed long ago. The Civil Aviation Safety Authority (CASA) is simply cleaning house and formally removing this obsolete requirement from the rulebook.\n\n**Who is affected:** Owners and operators of Piper PA-31 series aeroplanes. As of **31 July 2008**, you no longer need to worry about this particular inspection or carry proof of compliance for it."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled","history":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled/history","analysis":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled/analysis","conflicts":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled/conflicts","importantCases":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled/important-cases","documents":"/api/acts/ad-pa-31-95-elevator-bellcrank-assembly-cancelled/documents"}}
