The action involves following a service bulletin from the manufacturer (Edo-Aire Mitchell Service Bulletin MB-6) to address a problem with the **aileron control tube** (the metal rod that connects the pilot's control wheel to the wing flaps that make the plane roll) and the **automatic pilot roll servo** (the motor that moves those controls when autopilot is engaged).\n\n**Who it affects:** Owners and operators of Cessna 182E, 182F, 182G and 182H aircraft with specific Mitchell autopilot models installed, *unless* the aircraft has already been modified according to Service Letter ML32.\n\n**Why it matters:** This addresses a potential safety defect where the autopilot system could interfere with or damage the aileron control system, potentially causing loss of roll control. The directive gives a hard deadline: the fix must be done within 25 hours of flight time after 25 February 1972.\n\n**Key point:** This is a historical directive from 1972 (note the \"2/72\" reference), so for modern operators, compliance would have been required decades ago. The reference to \"FAA AD 72-2-6\" shows Australia was harmonising with a US Federal Aviation Administration safety directive."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The text supplied sets a specific, narrow requirement for identified Cessna 182 models fitted with listed Mitchell autopilot roll servo models and not modified by Service Letter ML32.
