Airworthiness Directive · Amendment 39-17480 · Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-725A1-12 turbofan engines with fuel pump tube part number (P/N) FW64852 installed.
We are adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-725A1-12 turbofan engines with fuel pump tube part number FW64852 installed. This AD requires removal of the affected fuel pump tube and its replacement with a part eligible for installation. This AD was prompted by the discovery that cracks have occurred in the affected fuel pump tube between the fuel metering unit and the main fuel pump. We are issuing this AD to prevent loss of fuel supply to the engine, which could result in in-flight engine shutdown of one or more engines, loss of thrust control and damage to the airplane.
Unless already done, within 15 days after the effective date of the AD, remove fuel pump tube P/N FW64852 and replace with a part eligible for installation. Guidance on removing the affected fuel pump tube can be found in RRD Service Bulletin SB-BR700-73-101847, dated May 17, 2013.
After the effective date of this AD, do not install fuel pump tube P/N FW64852 onto any engine or install an engine with fuel pump tube P/N FW64852 onto any aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
