EASA AD 2019-0096
Wings — Landing Flap Support Arms — Inspection
Summary
EASA Airworthiness Directive 2019-0096 is an airworthiness directive affecting Dornier 328-100 aeroplanes with serial numbers 3032 to 3086 inclusive. It addresses the inspection of landing flap support arms due to missing rivets that could compromise the structural integrity of the flap arms. The directive requires inspections and corrective actions to ensure continued airworthiness of the affected aircraft.
What Changed
EASA Airworthiness Directive 2019-0096 supersedes the previous LBA Germany AD 97-328 and introduces a one-time inspection requirement for Group 2 Dornier 328-100 aeroplanes, in addition to retaining inspection and modification requirements for Group 1 aeroplanes. It mandates inspections for missing rivets and corrective installation of fasteners where necessary to address the unsafe condition.
Why It Matters
This directive is critical for aviation professionals because missing rivets on landing flap support arms can reduce the fatigue life of these components, potentially leading to structural failure. Operators and maintenance organizations must comply to ensure flight safety and regulatory compliance, preventing possible flap arm failure during operation.
What To Do
Operators of Group 1 Dornier 328-100 aeroplanes must inspect the landing flap support arms before exceeding 10,000 flight cycles since first flight. Group 2 operators must perform inspections within 500 flight hours or 7 months from the effective date of 14 May 2019. If missing rivets are found, the missing fasteners must be installed before the next flight following the service bulletin instructions.
