Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines

FAA / Federal Register · 2021-24056

The FAA is revising a notice of proposed rulemaking (NPRM) that applied to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000 model turbofan engines. This action revises the NPRM by reopening the comment period because the NPRM was placed in incorrect Docket No. FAA-2021-0637 instead of Docket No. FAA-2021-0662. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since commenters experienced difficulties in commenting on the NPRM, the FAA is requesting comments on this SNPRM.
