Airworthiness Directive · Amendment 39-14218 · Rolls-Royce Deutschland Ltd & Co KG (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
Rolls-Royce Deutschland Ltd & Co KG (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 Turbofan Engines
This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. These engines are installed on, but not limited to, McDonnell Douglas model 717-200 airplanes.
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. This AD requires a onetime inspection of the Independent Overspeed Protection (IOP) unit, part number (P/N) 112E9321G2, for 19 specific serial numbers (SNs), and removal from service of those units. This AD results from a report that incorrect capacitors were installed in 19 IOP units. The incorrect capacitor in the IOP unit can lead to an inadvertent IOP command resulting in an in-flight engine shutdown. We are issuing this AD to prevent inadvertent dual-engine in-flight shutdown.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Within 10 flight cycles after the effective date of this AD, inspect each engine's IOP unit, part number 112E9321G2, for the serial numbers listed in the following Table 1:
| LHBR0371 | LHBR0372 | LHBR0373 | LHBR0374 | LHBR0375 | LHBR0376 |
| LHBR0377 | LHBR0378 | LHBR0379 | LHBR0380 | LHBR0381 | LHBR0382 |
| LHBR0383 | LHBR0384 | LHBR0385 | LHBR0386 | LHBR0387 | LHBR0388 |
| LHBR0389 |
(g) If neither engine has an IOP unit listed in Table 1 of this AD, no further action is required.
(h) If both engines have IOP units listed in Table 1 of this AD installed, remove at least one of the IOP units from service before further flight.
(i) If one engine has an IOP unit listed in Table 1 of this AD, remove the listed IOP from service no later than August 31, 2005.
(j) After the effective date of this AD, do not install any IOP units listed in Table 1 of this AD onto any engine.
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.
