What to do
Operators of affected Dassault Mystère-Falcon 900, Falcon 900EX, Falcon 2000, and Falcon 2000EX aeroplanes must perform a one-time inspection of the wing anti-ice system within six months of 7 March 2023, following the instructions in the applicable Dassault service bulletin. If any discrepancies are found, corrective actions must be completed before the next flight. Alternatively, compliance can be achieved by performing the inspection as described in the updated Aircraft Maintenance Manual task.
Summary
EASA Airworthiness Directive 2023-0041 is an airworthiness directive issued by the European Union Aviation Safety Agency addressing the wing anti-ice system inspection for Dassault Aviation Mystère-Falcon 900, Falcon 900EX, Falcon 2000, and Falcon 2000EX aeroplanes. The directive mandates inspection of the wing anti-ice system to detect leaks or installation issues that could impair system performance. It applies to specific serial numbers of these aircraft models.
What changed
This new airworthiness directive introduces a one-time inspection requirement for the wing anti-ice system to identify leaks caused by incorrect installation of the Wiggins coupling or detachment of the pressure switch line. Dassault Aviation has updated the Aircraft Maintenance Manual task and issued service bulletins to guide the inspection and corrective actions. The directive also accepts inspections performed according to the updated AMM task as an alternative method of compliance.
Why it matters
This directive is critical for aviation professionals because undetected leaks in the wing anti-ice system can reduce the effectiveness of ice protection, potentially compromising aircraft control and safety. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid operational restrictions. The directive provides clear instructions to prevent performance degradation of the wing anti-ice system, thereby enhancing flight safety.
