EASA AD 2026-0162 — Flight Controls – Roll Spoiler Actuator Mount – Inspection

Summary

EASA Airworthiness Directive 2026-0162 is an airworthiness directive addressing the inspection of roll spoiler actuator mounts on Dornier 328-100 aeroplanes. It mandates a one-time inspection to detect corrosion around the pivot-bearing area of the roll spoiler actuator mount, which is difficult to detect due to its concealed location. The directive applies to all manufacturer serial numbers of Dornier 328-100 aircraft and requires reporting of inspection results to Deutsche Aircraft GmbH.

What Changed

This new airworthiness directive introduces a mandatory inspection of the roll spoiler actuator mounts to identify corrosion that could compromise roll spoiler actuation. It requires operators to inspect affected parts within 5,000 flight hours or 30 months from the effective date and to report findings to Deutsche Aircraft GmbH. Corrective actions must be taken if corrosion or cracks are found, following approved instructions.

Why It Matters

This directive is critical for maintaining flight safety by preventing potential loss of roll spoiler control, which could lead to uncommanded roll spoiler movement and reduced aircraft control. Operators and maintenance organizations must ensure compliance to avoid unsafe conditions and support ongoing fleet monitoring. The directive also facilitates data collection to assess the ageing effects on the affected parts.

What To Do

Operators of Dornier 328-100 aeroplanes must inspect each roll spoiler actuator mount within 5,000 flight hours or 30 months after 25 August 2026, whichever occurs first. If corrosion or cracks are found, corrective actions must be coordinated with Deutsche Aircraft GmbH before further flight. Regardless of findings, inspection results must be reported to Deutsche Aircraft GmbH within 30 days after inspection or after the effective date, whichever is later.
