EASA AD 2019-0304R1: Engine — Operational Restrictions

What to do

Operators of Group 1 aeroplanes must remove one affected engine within three months of the directive's effective date and ensure only one affected engine remains installed. For Group 2 aeroplanes, installation of affected engines is prohibited unless the other engine is not affected. Compliance must be verified against the updated list of serial numbers and engine parts, with Airbus modification 164937 providing certain exemptions.

Summary

EASA Airworthiness Directive 2019-0304R1 is an operational restriction directive affecting Airbus A320 and A321 NEO aeroplanes equipped with certain International Aero Engines (IAE) PW1000G series engines. It addresses the risk of damage and potential fracture of low pressure turbine (LPT) third stage blades, which could lead to dual engine in-flight shutdown. The directive applies to specific aircraft serial numbers and engine part numbers identified in the document.

What changed

This revision removes certain Airbus aeroplanes with CFM International LEAP-1A engines that were mistakenly included in the original applicability. It provides a corrected list of affected aircraft serial numbers and clarifies operational restrictions regarding affected engines. The directive remains an interim action pending further regulatory updates.

Why it matters

This directive is critical for aviation professionals to prevent potential engine failures caused by damaged turbine blades, which could compromise flight safety. Operators and maintenance teams must ensure compliance to avoid dual engine shutdowns and maintain aircraft airworthiness. It impacts engine installation policies and ongoing maintenance practices for affected Airbus A320 and A321 NEO models.
