EASA AD 2020-0045
Fuel — Fuel Pressure Sensor — Inspection / Replacement
Summary
EASA Airworthiness Directive 2020-0045 is an airworthiness directive addressing the Pipistrel Vertical Solutions Virus SW 121 aeroplanes, specifically serial numbers VSW1210001 to VSW1210041. It mandates inspection and replacement of the fuel distribution block, Rotax Part Number 851328, associated with the fuel pressure sensor to prevent fuel leakage. The directive includes instructions for inspection, replacement, and modification of the installation to ensure continued airworthiness.
What Changed
EASA Airworthiness Directive 2020-0045 supersedes the previous AD 2018-0281 and expands its applicability to include additional serial numbers of the Virus SW 121 aeroplanes. It retains the original inspection and replacement requirements but adds new compliance deadlines for the newly included aircraft groups. The directive also updates the service bulletin references and clarifies the conditions for terminating actions and parts installation.
Why It Matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to fuel leakage and possibly an in-flight fire. Operators and maintenance organizations must comply to ensure the safety and airworthiness of affected aircraft. Compliance helps prevent operational disruptions and ensures adherence to regulatory requirements, reducing risk and liability.
What To Do
Operators of Virus SW 121 aeroplanes must visually inspect the fuel distribution block for damage or leakage within 14 days of the applicable effective dates depending on aircraft group. If damage or leakage is found, the affected part must be replaced and the installation modified before the next flight. All affected aircraft must complete the replacement and modification within 25 flights or 2 months, whichever occurs first, to terminate post-flight check requirements.
