AD 2022-08-16

 (a) Effective Date

    This airworthiness directive (AD) is effective May 31, 2022.

(b) Affected ADs

    This AD replaces AD 2020-20-07, Amendment 39-21263 (85 FR 62975, 
October 6, 2020) (AD 2020-20-07).

(c) Applicability

    This AD applies to Rolls-Royce Deutschland Ltd & Co KG (RRD) 
Trent 1000-AE3, Trent 1000-CE3, Trent 1000-D3, Trent 1000-G3, Trent 
1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, 
Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, Trent 1000-R3, Trent 
7000-72, and Trent 7000-72C model turbofan engines installed as 
identified in European Union Aviation Safety Agency (EASA) AD 2019-
0282R1, dated August 25, 2021 (EASA AD 2019-0282R1).

(d) Subject

    Joint Aircraft Service Component (JASC) Code 7230, Turbine 
Engine Compressor Section.

(e) Unsafe Condition

    This AD was prompted by a report of crack findings in the front 
air seal on the intermediate-pressure compressor (IPC) shaft 
assembly during the stripping of a flight test engine. The FAA is 
issuing this AD to prevent failure of the IPC shaft assembly. The 
unsafe condition, if not addressed, could result in loss of thrust 
control and reduced control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified in paragraph (h) of this AD: Perform all 
required actions within the compliance times specified in, and in 
accordance with, EASA AD 2019-0282R1.

(h) Exceptions to EASA AD 2019-0282R1

    (1) Where EASA AD 2019-0282R1 requires compliance from November 
27, 2019, the effective date of EASA AD 2019-0282, this AD requires 
compliance from November 10, 2020, the effective date of FAA AD 
2020-20-07.
    (2) Where EASA AD 2019-0282R1 requires contacting Rolls-Royce 
for approved corrective actions if a crack is detected during any 
on-wing inspection and in-shop inspection, this AD requires removing 
the IPC shaft assembly and replacing it with a part eligible for 
installation before further flight.
    (3) Where EASA AD 2019-0282R1 defines a serviceable part as an 
IPC shaft assembly which is not an affected part; or an affected 
part which is new (never previously installed on an engine); or an 
affected part that, before (re)installation, has passed (no crack 
detected) an inspection in accordance with the instructions of the 
NMSB, this AD also includes in that definition an IPC shaft assembly 
that, before (re)installation, has passed a visual inspection (no 
crack detected) of the exposed part using FAA-approved maintenance 
procedures.
    (4) Where EASA AD 2019-0282R1 references on-wing inspections, 
this AD allows for a visual inspection of the IPC shaft assembly 
using FAA-approved maintenance procedures as a substitute for any 
on-wing borescope inspection if the affected part is exposed, 
provided that the compliance times specified in this AD are not 
exceeded.
    (5) This AD does not mandate compliance with the ``Remarks'' 
section of EASA AD 2019-0282R1.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
ECO Branch, send it to the attention of the person identified in 
paragraph (j)(1) of this AD. Information may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) AMOCs approved previously for AD 2020-20-07 are approved as 
AMOCs for the corresponding provisions of this AD.
