EASA AD 2025-0106: Wings — Pylon Primary Structure — Inspection

What to do

Operators of affected Airbus A350-1041 aeroplanes must inspect the fasteners on the pylon primary structure before exceeding 20,000 flight cycles since first flight. If any discrepancies are found, they must contact Airbus for approved repair instructions and complete the corrective actions within the specified compliance time, not exceeding 20,000 flight cycles. Inspections can be performed during separate maintenance visits for left-hand and right-hand pylons.

Summary

EASA Airworthiness Directive 2025-0106 is an airworthiness directive issued by EASA concerning Airbus A350-1041 aeroplanes. It mandates inspection of the primary structure of the left-hand and right-hand pylons for missing chamfers under critical fastener heads. This directive applies specifically to certain manufacturer serial numbers of the Airbus A350-1041 model.

What changed

This new airworthiness directive introduces a one-time inspection requirement for the pylon primary structure fasteners on specified Airbus A350-1041 aircraft. It addresses a newly identified issue of missing chamfers under fastener heads, which may compromise structural integrity. The directive also requires corrective actions if discrepancies are found during inspection.

Why it matters

This directive is critical for maintaining the structural integrity and safety of affected Airbus A350-1041 aircraft. Operators and maintenance organizations must ensure compliance to prevent potential fatigue damage that could reduce the aircraft's lifespan. Compliance teams need to track affected serial numbers and inspection deadlines to avoid regulatory violations and ensure continued airworthiness.
