What to do
Operators of Group 1 PC-24 aeroplanes must install the Utility Management System software update to Build 7.3 within 30 days from 1 October 2020. Installation of affected software versions is prohibited on all PC-24 aircraft from the effective date. Maintenance personnel should follow Pilatus Service Bulletin 42-010 for update instructions and ensure no affected parts are installed thereafter.
Summary
EASA Airworthiness Directive 2020-0200 is an official safety directive addressing Pilatus PC-24 aeroplanes equipped with the Integrated Modular Avionics Utility Management System. It mandates a software update to the Utility Management System to resolve critical failures affecting environmental controls, oxygen mask deployment, and autopilot functions. This directive applies to all PC-24 aircraft with software version Build 7 or earlier installed.
What changed
This new directive introduces a mandatory update to the Utility Management System software to Build 7.3 standard to correct dual Ethernet communication channel failures. It also prohibits the installation or reinstallation of affected software versions on any PC-24 aeroplane. The directive is the first of its kind addressing this specific software issue for the PC-24.
Why it matters
The directive is crucial for maintaining safe operation of the PC-24 by preventing failures that could degrade multiple aircraft systems and increase pilot workload. Compliance ensures continued airworthiness and reduces the risk of in-flight emergencies related to avionics system failures. Operators and maintenance teams must prioritize this update to avoid potential safety hazards and regulatory non-compliance.
