Federal Register / Vol. 78, No. 20 / Wednesday, January 30, 2013 / Rules and Regulations
RB211–Trent 972–84, RB211–Trent 972B–84,
RB211–Trent 977–84, RB211–Trent 977B–84,
and RB211–Trent 980–84 engines, all serial
numbers.
(d) Reason
This AD was prompted by a Trent 900
engine experiencing low-pressure turbine
(LPT) stage 2 disk interstage seal material
loss and increased low-pressure rotor
vibration while in flight. We are issuing this
AD to prevent cracks in the LPT disk, which
could result in uncontained engine failure
and damage to the airplane.
(e) Actions and Compliance
Unless already done, do the following.
(1) After every flight after the effective date
of this AD, review the Engine Health
Monitoring (EHM) low-pressure rotor (N1)
vibration data. If you find that the maximum
and average vibrations exceed 0.7 inches/sec
(ips) and 0.5 ips, respectively, then within 10
engine flight cycles, confirm that the
vibration data was not the result of indicator
error.
(2) If you cannot show that the vibration
increase was caused by indicator error,
inspect the LPT disk seal fins and interstage
seals. Use RR Repeater Technical Variance
125060, Issue 1, dated July 27, 2012, to do
the inspections.
(3) After the effective date of this AD, at
each engine shop visit inspect the LPT disk
seal fins and interstage seals. Use RR Alert
Non-Modification Service Bulletin RB.211–
72–AH054, Revision 1, dated November 5,
2012, or Initial Issue, dated September 14,
2012, to do the inspections.
(4) If, during the inspection required by
paragraphs (e)(2) or (e)(3) of this AD, you find
any cracks in the disk seal fins or that the
interstage seals are missing seal material,
replace the parts with hardware eligible for
installation before returning the engine to
service.

(f) Definitions
For the purposes of this AD, a shop visit
is defined as whenever engine maintenance
performed prior to reinstallation requires one
of the following:
(1) Separation of a pair of major mating
engine module flanges. However, separation
of flanges solely for the purpose of shipment
without subsequent internal maintenance is
not a shop visit. Separation of the external
gearbox engine mating flanges or removal of
the external gearbox is also not classified as
a shop visit.
(2) Removal of a disk, hub, or spool.
