It requires owners and operators of specific Cessna 210 aircraft to take urgent safety action.\n\n**What it does:**\n- **Inspects** the aileron control tube (a metal rod that connects the pilot's control wheel to the wing flaps that make the plane roll left or right)\n- **Removes** the automatic pilot roll servo (a motor that helps the autopilot control the plane's banking/turning) on certain Mitchell autopilot models\n\n**Who it affects:**\n- Owners of Cessna 210B, 210C, 210-5, 210-5A, 210-D and 210E aircraft\n- **Only if** fitted with specific Mitchell autopilot models (AK086, AK086R, AK086E, AK112, AK120, AK120E, AK120E-3, AK126, AK126E or AK126E-3)\n- **Only if** the aircraft has **not** been modified according to Edo-Aire Mitchell Service Letter ML-32\n\n**Why it matters:**\nThis directive addresses a serious safety defect. The autopilot roll servo can interfere with the aileron control tube, potentially causing loss of roll control — meaning the pilot might not be able to turn the aircraft or keep it level. This creates a significant crash risk.\n\n**Compliance deadline:**\nAircraft must be inspected and the servo removed within **25 hours of flight time** after 25 February 1972.\n\n**Technical references:**\n- Edo-Aire Mitchell Service Bulletin MB-6, or\n- FAA Airworthiness Directive 72-2-6 (the US equivalent safety order)"},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The provided text does not indicate any change in scope from the original directive.
