Summary
Final rule; request for comments.
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 engines. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these engines. This AD was prompted by reports of non- conformances leading to low oil pressure events on low life oil pumps. This AD requires de-pairing of engines on airplanes with two affected engines installed to ensure no more than one affected oil pump is installed on twin-engine airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
