FAA Proposes Airworthiness Directives for Rolls-Royce Trent 1000 Engines and Airbus A320 Family Aircraft

The Federal Aviation Administration (FAA), part of the Department of Transportation, is proposing new airworthiness directives affecting specific Rolls-Royce Trent 1000 series engines and Airbus A318, A319, A320, and A321 aircraft. - Government Buyer: - Department of Transportation, Federal Aviation Administration, Operational Safety Branch - OEMs Mentioned: - Rolls-Royce Deutschland Ltd & Co KG (Trent 1000 engines) - Airbus SAS (A318, A319, A320, A321 aircraft) - Products/Services Requested: - Repetitive borescope inspections of the high-pressure compressor (HPC) rear drum cavity and cavities between each HPC rotor disc for Rolls-Royce Trent 1000 engines - Modification of the bolting arrangement at the HPC rotor shaft to high-pressure turbine (HPT) rotor disc interface as a permanent corrective action - Special detailed inspection and replacement of nose landing gear sliding tubes on Airbus A318, A319, A320, and A321 aircraft if overheat damage or cracks are found - Unique/Notable Requirements: - The directive targets prevention of unsafe conditions, such as the release of an HPC mini-disc anti-rotation block in Rolls-Royce engines and overheat damage/cracks in Airbus nose landing gear - No specific part numbers or purchase quantities are provided; actions are compliance-based, not direct procurement - Operators must comply with repetitive inspections and, if necessary, perform modifications or replacements as specified by the OEMs

Description

The FAA proposes to supersede Airworthiness Directive (AD) 2025-26-03, which applies to certain Rolls-Royce Deutschland Ltd & Co KG Model Trent 1000 series engines. The AD requires repetitive borescope inspections of the high-pressure compressor rear drum cavity and cavities between each HPC rotor disc, with possible removal of the engine from service depending on inspection results. The proposed AD would also allow an alternative method of complying with inspections if certain actions are accomplished and require modification of the bolting arrangement as a terminating action for the repetitive inspections. This action addresses an unsafe condition related to the potential release of an HPC mini-disc anti-rotation block into the HPC assembly during engine operation.
