EASA AD 26-082
Flight Controls – Roll Spoiler Actuator Mount – Inspection
Summary
EASA Airworthiness Directive Proposal PAD No. 26-082 addresses the inspection of roll spoiler actuator mounts on Dornier 328-100 aeroplanes. The directive targets corrosion issues found around the pivot-bearing area of the roll spoiler actuator mounts, which could affect flight control. It applies to all manufacturer serial numbers of Dornier 328-100 aircraft.
What Changed
This new proposed airworthiness directive introduces a mandatory one-time inspection of the roll spoiler actuator mounts to detect corrosion or cracks. It requires corrective actions if corrosion is found and mandates reporting of inspection results to Deutsche Aircraft GmbH. The directive is an interim measure pending further monitoring and potential future actions.
Why It Matters
This directive is critical for aviation professionals as undetected corrosion could lead to loss of roll-spoiler actuation, causing uncommanded roll-spoiler movement and reduced aircraft control. Operators and maintenance teams must ensure timely inspections to maintain flight safety and regulatory compliance. The reporting requirement supports ongoing fleet monitoring and safety management.
What To Do
Operators of Dornier 328-100 aeroplanes must inspect each roll spoiler actuator mount within 5,000 flight hours or 30 months from the effective date of the directive, 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 within 30 days after inspection or after the effective date, whichever is later.
