EASA AD 2024-0246
Electrical Power — Software and Data Recording System — Upgrade
Summary
EASA Airworthiness Directive 2024-0246 is an official regulatory document addressing the electrical power software and data recording system upgrade for Pipistrel Vertical Solutions d.o.o. Virus SW 128 aeroplanes, specifically serial numbers VSW1280002 to VSW1280117. The directive mandates updates to the system controller software and SD card replacement to ensure accurate high voltage battery state of charge indication.
What Changed
This new Airworthiness Directive introduces mandatory software package updates, inspections of system controller connectors, replacement of affected SD cards, and ground run tests for the high voltage battery state of charge. It prohibits installation of older software versions and sets conditions for software and SD card installations based on battery group classifications.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety issue where incorrect battery state of charge readings could lead to forced landings and potential damage or injury. Operators and maintenance teams must comply to maintain aircraft airworthiness and ensure safe operation of affected Virus SW 128 aeroplanes. Compliance with this AD helps prevent operational disruptions and enhances reliability of the electrical power system.
What To Do
Operators of affected Virus SW 128 aeroplanes must install specified software updates within two months of 31 December 2024, inspect system controller connectors before the next flight after software installation, replace affected SD cards if no discrepancies are found, and perform the high voltage battery state of charge ground run test. Any discrepancies found during inspection require contacting Pipistrel for approved repair instructions prior to flight. Installation of prohibited software versions is not allowed from the effective date.
