What to do
Operators of PC-24 aeroplanes with serial numbers 101 to 125 must replace the affected electrical wiring splices with serviceable parts within three months from 29 July 2019, following the instructions in Pilatus Aircraft PC-24 Service Bulletin No. 30-002. After replacement, the affected parts must not be reinstalled on the aircraft. Maintenance and compliance teams should ensure timely action to meet the directive requirements.
Summary
EASA Airworthiness Directive 2019-0166 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Pilatus Aircraft Ltd PC-24 aeroplanes with manufacturer serial numbers 101 through 125. The directive addresses the replacement of specific pitot and static electrical wiring splices to prevent potential safety hazards. It mandates the replacement of affected electrical wiring splices with serviceable parts to ensure continued safe operation of the aircraft.
What changed
This new airworthiness directive introduces a mandatory replacement of electrical wiring splices having Part Number 971.31.32.561 near the right-hand pitot/static connector on frame 10 with serviceable parts having Part Number 971.31.32.641. It prohibits the reinstallation of the affected parts after replacement and requires compliance within a specified timeframe.
Why it matters
This directive is critical for aviation professionals because the affected wiring splices showed signs of overheating, which could lead to an uncontrolled fire in the cockpit or loss of probe heating and de-icing functions. Compliance ensures the safety of flight operations and prevents potential control issues caused by malfunctioning ice and rain protection systems. Operators and maintenance teams must address this to maintain airworthiness and regulatory compliance.
