SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all RRD Model 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, and Trent 1000-R3 engines. The NPRM
published in the Federal Register on September 29, 2023 (88 FR 67121).
The NPRM was prompted by EASA AD 2023-0087, dated April 26, 2023 (EASA
AD 2023-
[[Page 252]]
0087) (also referred to as the MCAI), issued by EASA, which is the
Technical Agent for the Member States of the European Union. The MCAI
states that the RRD engine time limits manual (TLM) provides
instructions for visual inspection of the IP8 and HP3 air transfer
tubes and front bearing housing IP8 air feed tubes for cracking,
damage, or air leakage wear at intervals consistent with critical part
life assessments. Also, certain inspection intervals mandated by the
MCAI, and not previously included in the TLM, are shorter than the
engine shop visit intervals. Thus, more frequent visual inspections of
the IP8 and HP3 air transfer tubes and front bearing housing IP8 air
feed tubes are necessary. The manufacturer issued service information
that provides instructions for visual inspections of the IP8 and HP3
air transfer tubes and front bearing housing IP8 air feed tubes.
In the NPRM, the FAA proposed to require initial and repetitive
visual inspections of the IP8 and HP3 air transfer tubes and front
bearing housing IP8 air feed tubes for cracking, damage, or air leakage
wear, and replacement, if necessary. The FAA is issuing this AD to
address the unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1892.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from The Boeing Company (Boeing).
Boeing supported the NPRM without change.
Conclusion
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI referenced above. The FAA reviewed the relevant data,
considered the comment received, and determined that air safety
requires adopting the AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, this AD is adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2023-0087, which specifies procedures for
performing initial and repetitive visual inspections of the IP8 and HP3
air transfer tubes and front bearing housing IP8 air feed tubes for
cracking, damage, or air leakage wear, and replacement if necessary.
This material is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in ADDRESSES.
Costs of Compliance
The FAA estimates that this AD affects 16 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection of air tubes........... 3 work-hours x $85 per $0 $255 $4,080
hour = $255.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need these replacements:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace IP8 air transfer tubes............. 2 work-hours x $85 per hour = $170. $7,600 $7,700
Replace HP3 air transfer tubes............. 2 work-hours x $85 per hour = $170. 11,900 12,070
Replace front bearing housing IP8 air feed 2 work-hours x $85 per hour = $170. 10,000 10,170
tubes.
----------------------------------------------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
