## Abstract

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd. & Co KG (RRD) (formerly Rolls- Royce plc) Model Tay 611-8, 620-15, 650-15, and 651-54 turbofan engines, with low pressure (LP) fuel tube, part number (P/N) JR33021A, installed. That AD currently requires initial and repetitive inspections of the LP fuel tubes. This AD requires the same inspections and adds a requirement to replace the fuel tube with a new design tube, as mandatory terminating action to the repetitive inspections. This AD results from the manufacturer introducing a new design fuel tube, which eliminates the unsafe condition. We are issuing this AD to prevent a dual-engine flameout due to fuel exhaustion, which could lead to forced landing and possible damage to the airplane.
