The situation could lead to partial or complete loss of aileron control and so a safety of flight Airworthiness Directive has been issued by the FAA to inspect all such aileron systems. This Directive reflects the content and urgency of the US FAA AD.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
