| 2017-26572 | Airworthiness Directives; Rolls-Royce plc Turbofan Engines | Rule | We are superseding airworthiness directive (AD) 2014-24-08 for all Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211- 535E4-C-37 turbofan engines with certain low-pressure (LP) fuel filter- to-high-pressure (HP) fuel pump tube assemblies, or HP fuel pump-to- fuel flow governor (FFG) or FFG-to-HP pump inlet overspill return tube assemblies and flanged adaptor, installed. AD 2014-24-08 required replacing certain LP fuel filter-to-HP fuel pump tube assemblies. This AD retains the requirement in AD 2014-24-08 to remove the LP fuel filter-to-HP fuel pump tube, adds new compliance thresholds, and requires installation of new HP fuel pump-to-FFG and FFG-to-HP pump inlet overspill return tube assemblies and flanged adaptor. This AD was prompted by fuel leaks that have occurred at the flanged joints of the HP fuel pump-to-FFG tube assembly and FFG-to-HP pump inlet overspill return tube assembly. We are issuing this AD to correct the unsafe condition on these products. | 2017-12-11 | 2017 | 12 | https://www.federalregister.gov/documents/2017/12/11/2017-26572/airworthiness-directives-rolls-royce-plc-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2017-12-11/pdf/2017-26572.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are superseding airworthiness directive (AD) 2014-24-08 for all Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211- 535E4-C-37 turbofan engines with certain low-pressure (LP) fuel filter- to-high-pressure (HP) fuel pump tube... |
