EASA AD 2017-0209R1
Integrated Modular Avionics — Internal Timer — Power Cycle (Reset)
EASA Airworthiness Directive 2017-0209R1 is an updated regulation addressing an internal timer issue in the Integrated Modular Avionics of Airbus A380-841, A380-842, and A380-861 aircraft. It applies to all serial numbers except those with Airbus modifications 77908 and 77909 incorporated during production. The directive mandates repetitive on-ground power cycles to reset the internal timer to prevent loss of communication between avionics systems.
