This typically involves inspecting, modifying, or replacing the control wheel adaptor to prevent potential control system failures.\n\n**When it had to be done:** The work had to be completed within **100 hours of flight time** after 31 August 1972. (Note: This is a historical directive from 1972, though Amendment 2 suggests it has been updated since.)\n\n**Why it matters:** Control wheel adaptors are critical safety components. If they fail, pilots could lose control of the aircraft. This AD ensures a known defect or wear issue is addressed before it causes an accident."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The document is labeled Amendment 2 (Amdt 2), indicating it modifies an earlier airworthiness directive.
