What to do
Operators of affected ATR 72 aircraft must modify the clamp installation of the electrical routing under panel 295CL within 1,000 flight hours or 8 months after 13 December 2019, whichever occurs later. The modification must be performed following the instructions in ATR Service Bulletin ATR72-92-1049. Alternative methods of compliance may be approved by EASA if properly substantiated.
Summary
EASA Airworthiness Directive 2019-0290 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting ATR 72 aeroplanes, excluding certain serial numbers and those with ATR modification 07988 embodied in production. The directive addresses an unsafe condition related to electrical wiring routing under panel 295CL on the left-hand side wing rear spar. It mandates a modification to the electrical harness clamp installation to prevent wire chafing and potential fire hazards.
What changed
This new airworthiness directive introduces a mandatory modification of the electrical routing clamp installation under panel 295CL on ATR 72 aircraft. The modification is based on ATR Service Bulletin ATR72-92-1049 and aims to correct wire chafing issues that could lead to wire failure or fire. No previous airworthiness directives are superseded by this AD.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving potential wire chafing that could cause smoke, flap extension difficulties, or uncontrolled fire. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent system failures that could compromise flight safety. Compliance also ensures adherence to European regulatory requirements for continuing airworthiness.
