This Airworthiness Directive requires owners/operators of certain AMD Fan Jet Falcon (Falcon 20/Mystere‑Falcon 200) aircraft to correct a known elevator-trim malfunction that can cause runaway trim and loss of control. It mandates manufacturer-approved repairs to eliminate the hazard after several reported incidents.

It applies to Falcons within specified serial-number ranges and directs compliance with the manufacturer’s service bulletins (existing or newly issued) for those affected aircraft. Compliance is mandatory to ensure continued safe operation.
