What to do
Operators of affected Airbus A320 and A321 aeroplanes must perform detailed inspections of the electrical harness clearance before exceeding 2,000 flight hours or within 300 flight hours after 1 March 2019, and repeat inspections every 2,000 flight hours thereafter. Any discrepancies found must be corrected before further flight. Additionally, Group 1 aeroplanes must be modified within 24 months after 1 March 2019, and Group 2 aeroplanes require conditional modification if certain service bulletins are embodied.
Summary
EASA Airworthiness Directive 2019-0035R1 is an updated regulatory document addressing inspection, repair, and modification requirements for the electrical harness installation on Airbus A320-251N, A320-271N, and A321-253N aeroplanes. It targets specific aircraft serial numbers excluding those with certain Airbus modifications already embodied in production. The directive aims to prevent potential fire or explosion risks caused by insufficient clearance between electrical harnesses and hydraulic pipes.
What changed
This revision clarifies that only aeroplanes equipped with new dampers for the yellow or green hydraulic systems, introduced by specific Airbus modifications or service bulletins, are affected by the unsafe condition. It adjusts the applicability and compliance requirements accordingly and specifies that modification is only required for Group 2 aeroplanes if certain service bulletins have been embodied in service.
Why it matters
This directive is critical for aviation professionals to ensure continued airworthiness and safety by preventing electrical harness chafing that could lead to ignition in flammable fluid zones. Operators and maintenance organizations must understand the specific aircraft groups affected and comply with inspection and modification requirements to mitigate fire or explosion risks. Compliance ensures regulatory adherence and reduces potential operational disruptions due to safety concerns.
