What to do
Operators must perform a functional check of each affected two-way valve within 21 days of 19 February 2024, the effective date. If discrepancies are found, the affected parts must be replaced or reworked before the next flight. Additionally, installation of affected parts is prohibited from the effective date, and inspection results must be reported to ATR within 30 days after the functional check.
Summary
EASA Airworthiness Directive 2024-0044-E is an emergency directive addressing the inspection of the engine fire extinguishing system on ATR 42 and ATR 72 aeroplanes. It specifically targets two-way valves with Part Number 446078 and certain serial numbers that may have incorrect marking and assembly. The directive mandates functional checks and corrective actions to ensure proper operation of the fire extinguishing system.
What changed
This new emergency AD introduces mandatory inspections and functional checks of affected two-way valves in the engine fire extinguishing systems of ATR 42 and ATR 72 aircraft. It prohibits installation of affected parts and requires replacement or rework of valves found with discrepancies. The AD is an interim measure pending further regulatory action.
Why it matters
This directive is critical for aviation professionals because incorrect assembly of the two-way valves could reduce the effectiveness of the engine fire extinguishing system, potentially compromising flight safety. Operators, maintenance organizations, and compliance teams must ensure timely inspections and corrective actions to maintain airworthiness and regulatory compliance.
