EASA AD 2018-0099: Fuel — Trim Tank Vent Pipes — Inspection

What to do

Operators of affected Airbus A380 aircraft must perform a one-time borescope inspection of the forward trim tank vent pipes within 32 months from 2018-05-24. If any blockages are detected, corrective actions and a detailed inspection of the horizontal tail plane torque box must be completed before the next flight. Any discrepancies found during the detailed inspection require contacting Airbus for approved repair instructions and timely compliance with those instructions.

Summary

EASA Airworthiness Directive 2018-0099 is an airworthiness directive issued for Airbus A380-841, A380-842, and A380-861 aeroplanes. It mandates a one-time borescope inspection of the forward trim tank vent pipes to detect any blockages that could affect the structural integrity of the horizontal tail plane. The directive also requires corrective actions and detailed inspections if blockages are found.

What changed

This new airworthiness directive introduces a mandatory inspection requirement for the forward trim tank vent pipes on certain Airbus A380 models. It addresses the absence of a production line test on some aircraft that could lead to undetected blockages and potential overpressure in the horizontal tail plane structure. The directive includes instructions for corrective actions and repairs if discrepancies are found during inspections.

Why it matters

This directive is critical for maintaining the structural integrity and safety of the Airbus A380's horizontal tail plane by preventing overpressure caused by blocked vent pipes. Operators and maintenance organizations must ensure compliance to avoid potential structural damage and ensure continued airworthiness. Compliance with this directive helps prevent unsafe conditions that could compromise flight safety.
