Airworthiness Directive · Amendment 39-13962 · Rolls-Royce Deutschland Ltd. & Co KG (formerly Rolls-Royce plc), Model Tay 611-8, 620-15, 650-15, and 651-54 Turbofan Engines
Rolls-Royce Deutschland Ltd. & Co KG (formerly Rolls-Royce plc), Model Tay 611-8, 620-15, 650-15, and 651-54 Turbofan Engines
This AD applies to 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. These engines are installed on, but not limited to, Fokker F.28 Mark 0100 airplanes, Supplemental Type Certificate No. SA842SW, Boeing 727 airplanes, and Gulfstream G-IV airplanes.
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.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Before further flight, for Tay 611-8 and 651-54 turbofan engines with part 4 of RRD service bulletin (SB) TAY-73-1194 incorporated, inspect the LP fuel tube for fretting, and replace as necessary. Use 3.C.1. through 3.C.13. of the Accomplishment Instructions of RRD Service Bulletin (SB) No. TAY-73-1553, Revision 2, dated April 23, 2003.
(g) Before further flight, for Tay 620-15 and 650-15 turbofan engines, inspect the LP fuel tube for fretting, and replace as necessary. Use 3.C.1. through 3.C.13. of the Accomplishment Instructions of RRD SB No. TAY-73-1593, dated April 23, 2003.
Thereafter, inspect the LP fuel tube for fretting, at intervals not to exceed 2,000 hours time-in-service (TIS) since the last inspection, and replace as necessary. Use 3.C.1. through 3.C.13. of the Accomplishment Instructions of RRD SBs referenced in paragraphs (f) and (g) of this AD.
(i) As mandatory terminating action to the repetitive inspections required by this AD, replace fuel tube, P/N JR33021, with a fuel tube P/N that is not listed in this AD. Information on fuel tube replacement can be found in RRD SB No. TAY-73-1592, dated April 30, 2003. Use the following compliance times:
(1) For fuel tubes with fewer than 4,000 hours TIS on the effective date of this AD, replace fuel tube within 10 additional cycles-in-service or before reaching 4,000 hours TIS, whichever occurs later.
(2) For fuel tubes with 4,000 or more hours TIS on the effective date of this AD, replace fuel tube before June 30, 2005.
