EASA AD 2018-0022
Ice and Rain Protection — Wing Anti-Ice System / Anti-Ice Pipe — Inspection / Replacement
Summary
EASA Airworthiness Directive 2018-0022 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Dassault Aviation Falcon 2000 and Falcon 2000EX aeroplanes equipped with specific wing anti-ice pipes. The directive mandates inspections and possible replacement of the wing anti-ice system's ball joint and anti-ice pipe to address potential ice protection system failures. It applies to aircraft with part numbers F2MA724561A1 or F2MA724561A2, excluding those modified by Dassault modifications M5000 or M5001.
What Changed
EASA Airworthiness Directive 2018-0022 introduces a new requirement for repetitive inspections of the ball joint downstream of the wing anti-ice valve and corrective actions if discrepancies are found. It also requires inspections of the wing anti-ice pipes based on findings. This directive is a new regulation addressing metallic debris issues found in the wing anti-ice system, which had not been previously mandated.
Why It Matters
This directive is critical for aviation professionals because undetected debris in the wing anti-ice system can restrict airflow, leading to insufficient ice protection and potential significant ice accumulation on the wings. This condition poses a serious safety risk, including possible loss of control of the aircraft. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and flight safety.
What To Do
Operators of affected Falcon 2000 and Falcon 2000EX aircraft must perform inspections of the ball joint downstream of the wing anti-ice valve within 25 months of 12 February 2018 and repeat these inspections every 25 months thereafter. If any discrepancies are found during inspections, corrective actions must be completed before the next flight according to the applicable Dassault Service Bulletins F2000-441 or F2000EX-413. No terminating action is provided, so ongoing compliance is required.
