EASA AD 2024-0072
Information Systems — Electronic Display Unit — Replacement
Summary
EASA Airworthiness Directive 2024-0072 is an airworthiness directive addressing the replacement of electronic display units (EDU) on Dassault Aviation Falcon 900EX, Falcon 2000EX, and Falcon 7X aircraft. The directive targets CMA-1310 EDUs with specific part numbers and modification statuses that have been found to have lithium-polymer battery swelling issues. It mandates replacement with modified units to ensure continued safe operation.
What Changed
This new airworthiness directive introduces a mandatory replacement of affected CMA-1310 electronic display units that have lithium-polymer batteries prone to swelling and potential thermal runaway. It requires operators to replace these units with serviceable parts that have the internal battery removed and updated firmware. Additionally, it prohibits reinstalling affected parts after removal.
Why It Matters
This directive is critical for aviation professionals because it addresses a significant safety risk involving potential fire or explosion in the cockpit due to battery failure in electronic display units. Operators and maintenance organizations must ensure compliance to avoid unsafe conditions and regulatory penalties. It also impacts maintenance planning and parts inventory management for affected Falcon aircraft.
What To Do
Operators of Falcon 900EX, Falcon 2000EX, and Falcon 7X aircraft with affected CMA-1310 EDUs must replace these units within 12 months or 800 flight hours from 29 March 2024, whichever occurs first. During replacement, the external battery must be inspected and replaced if defective. Installation of affected parts is prohibited after modification or from the effective date for unaffected aircraft.
