EASA AD 2025-0019-E
Engine / Electrical Power — Internal Generator — Inspection / Replacement of Oil Spray Nozzle
Summary
EASA Airworthiness Directive 2025-0019-E is an emergency directive addressing BRP-Rotax 912i, 915i, and 916i series engines installed on various general aviation aeroplanes and powered sailplanes. It mandates inspection and possible replacement of the oil spray nozzle assembly, Part Number 456540, and generator stator assemblies to prevent potential engine failures. The directive applies to all serial numbers of the affected engines and aims to ensure continued airworthiness and safety.
What Changed
This new emergency directive introduces mandatory repetitive operational checks before each flight and a one-time inspection of the oil spray nozzle and generator stator assembly within 25 flight hours or 12 months. It prohibits installation or reinstallation of affected parts and requires replacement of any unserviceable components identified during inspections. The directive also provides instructions for corrective actions and defines serviceable parts eligibility.
Why It Matters
This directive is critical for aviation professionals because it addresses a manufacturing defect that could cause blockage of the oil spray nozzle, leading to generator damage and potential uncommanded engine shutdowns. Operators and maintenance organizations must comply to prevent in-flight engine failures, ensuring safety and regulatory compliance. It also impacts parts management by restricting installation of affected components.
What To Do
Affected operators must perform an operational check of the battery backup function before each flight starting from 20 January 2025. Within 25 flight hours or 12 months from that date, a one-time functional inspection of the oil spray nozzle and generator stator assembly must be completed following BRP-Rotax Alert Service Bulletin instructions. Any discrepancies found require immediate corrective action, including part replacement, and affected parts must not be installed on any engine or aircraft.
