Compliance with Rolls-Royce Trent 900 Alert Non-Modification Service Bulletin RB.211-72-AK586 is required.
Summary
EASA Airworthiness Directive 2020-0196 is an official regulatory document addressing the removal from service of certain high pressure/intermediate pressure bearing support assemblies in Rolls-Royce RB211 Trent 970-84, Trent 972-84, and Trent 972E-84 engines, commonly installed on Airbus A380 aircraft. The directive mandates inspection and replacement of affected parts to ensure continued airworthiness and safety of the engines and aircraft.
What changed
This new Airworthiness Directive introduces mandatory removal from service of specific high pressure/intermediate pressure bearing support assemblies identified by part numbers and serial numbers due to manufacturing defects involving salvage welding without adequate heat treatment. It prohibits installation of these affected parts on any engine and requires replacement during the next engine shop visit after the effective date.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to bearing support strut failure, overheating, and release of high-energy debris, risking damage to the aircraft and loss of control. Operators, maintenance organizations, and compliance teams must ensure affected engines are inspected and parts replaced to maintain safety and regulatory compliance.
