What to do
Operators and maintenance organizations must inspect affected LPT seal panels during each qualified shop visit and replace any cracked or life-expired parts before engine release to service. All affected parts must be replaced before exceeding 7,000 flight cycles or within 30 days after the directive's effective date, whichever is later.
Summary
EASA Airworthiness Directive 2021-0056 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Rolls-Royce RB211 Trent 970-84, Trent 972-84, and Trent 972E-84 engines, commonly installed on Airbus A380 aircraft. The directive addresses inspection and replacement requirements for low pressure turbine (LPT) seal panels with specific part numbers to prevent potential failures.
What changed
This directive introduces repetitive in-shop inspections of the outer weld of affected LPT seal panels and establishes a life limit of 7,000 flight cycles for these parts. It mandates removal and replacement of affected parts exceeding this life limit or found cracked during inspections, ensuring continued airworthiness and safety.
Why it matters
This directive is critical for aviation professionals as it prevents potential LPT seal panel failures that could release high-energy debris, risking damage to the aircraft and reduced control. Compliance ensures safe engine operation, reduces unscheduled maintenance, and aligns with regulatory requirements for continuing airworthiness.
