The work must follow the exact instructions in **Beechcraft Service Instruction No. 0064-067, Revision 1** (a manufacturer-issued technical manual).\n\n**When to do it:** Within 200 hours of flight time, **or** before 1 August 1969 — whichever comes first.\n\n**Why it matters:** Faulty jack pads can crack or fail when the aircraft is lifted for maintenance, potentially dropping the plane and causing catastrophic damage or injury."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad","history":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad/history","analysis":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad/analysis","conflicts":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad/conflicts","importantCases":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad/important-cases","documents":"/api/acts/ad-beech-56-6-centre-section-rear-spar-jack-pad/documents"}}
