What to do
Operators of affected PC-24 aeroplanes must modify the electrical harness installations during the next annual inspection or within 12 months after 30 July 2020, whichever occurs later. The modifications must follow the instructions in Pilatus Aircraft PC-24 Service Bulletin 91-001. Requests for alternative methods of compliance can be submitted to EASA if substantiated.
Summary
EASA Airworthiness Directive 2020-0158 is an official regulatory document addressing electrical harness installation modifications on Pilatus Aircraft Ltd PC-24 aeroplanes, specifically those with manufacturer serial numbers 101 to 160 inclusive. The directive mandates changes to ensure compliance with approved design standards to maintain airworthiness and safety.
What changed
This new Airworthiness Directive requires modification of the electrical harness installations in the nose bay, cockpit, fuselage, wing fairing, and rear fuselage areas of affected PC-24 aircraft. The modifications must be carried out according to Pilatus Aircraft PC-24 Service Bulletin 91-001 to correct non-compliant wiring installations discovered during production.
Why it matters
The directive addresses potential safety risks such as wire chafing, arcing, loss of system redundancy, smoke generation, and failure of power plant fire protection functions. Compliance is critical for operators and maintenance organizations to prevent electrical system failures and ensure continued airworthiness of the affected PC-24 aircraft.
