EASA AD 2020-0229
Fuel — Fuel Transfer Ejector — Replacement
Summary
EASA Airworthiness Directive 2020-0229 is an official safety directive issued by the European Union Aviation Safety Agency concerning Pilatus Aircraft Ltd PC-12/47E aeroplanes. It addresses a fuel system issue related to fuel transfer ejectors with incorrect nozzle diameters installed on certain PC-12/47E aircraft. The directive mandates replacement of these affected fuel transfer ejectors to ensure compliance with approved design data and maintain fuel system safety.
What Changed
This new Airworthiness Directive introduces a mandatory replacement of fuel transfer ejectors with part number 968.84.71.112 and specific supplier serial numbers that have an incorrect nozzle diameter. It prohibits the installation or reinstallation of these affected parts on any PC-12/47E aeroplanes. The directive also defines affected aircraft groups and outlines compliance timelines for replacement.
Why It Matters
This directive is critical for aviation professionals because the affected fuel transfer ejectors may restrict fuel flow due to ice accumulation, potentially reducing safety margins in the fuel system. Operators and maintenance organizations must ensure compliance to prevent fuel system malfunctions and maintain airworthiness. Failure to comply could lead to unsafe operating conditions and regulatory violations.
What To Do
Operators of PC-12/47E aeroplanes with affected fuel transfer ejectors must replace these parts with serviceable ones during the next scheduled inspection or within four months from 3 November 2020, whichever occurs first. Installation of affected parts is prohibited from the effective date of the directive. Maintenance teams should follow Pilatus Aircraft PC-12 Service Bulletin 28-014 for replacement instructions.
