What to do
Operators must perform the required non-destructive and visual inspections before exceeding specified flight hour or cycle thresholds depending on aircraft configuration. If any discrepancies are detected, they must contact Airbus for approved repair instructions and complete corrective actions before the next flight. If no discrepancies are found, all fasteners in the affected area must be replaced with new bolts and self-aligning nuts before the next flight.
Summary
EASA Airworthiness Directive 2020-0109 is an airworthiness directive issued by EASA affecting Airbus A350-941 aeroplanes, except those with Airbus modification 114295 incorporated in production. It mandates inspection and potential modification of the fuselage frame 98 flange feet between stringers 15 and 17 to ensure structural integrity. The directive addresses potential fatigue and damage tolerance issues in the rear cone of the fuselage.
What changed
This new airworthiness directive introduces a one-time non-destructive test inspection and detailed visual inspection of all fastener holes in the affected fuselage area. It requires corrective actions if discrepancies are found, including contacting Airbus for approved repair instructions or replacing all fasteners with new bolts and self-aligning nuts. The directive applies to specific aircraft configurations and sets inspection thresholds based on flight hours or cycles.
Why it matters
This directive is critical for maintaining the structural integrity of the Airbus A350 rear fuselage, preventing potential fatigue damage that could compromise safety. Operators and maintenance organizations must comply to avoid unsafe conditions that could lead to structural failure. Compliance ensures continued airworthiness and regulatory adherence, reducing risk and potential operational disruptions.
