You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done. Onetime Inspection (f) 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: Table 1.—Affected IOP Unit Serial Numbers             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. Alternative Methods of

This AD results from a report that incorrect capacitors were installed in 19 Independent Overspeed Protection (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.
