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– 


ddrumheller on DSK120RN23PROD with RULES1
252 Federal Register / Vol. 89, No. 2 / Wednesday, January 3, 2024 / Rules and Regulations 

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 regulations.gov 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

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection of air tubes ............ 3 work-hours × $85 per hour = $255 ..................................... $0 $255 $4,080 

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

Action Labor cost Parts cost Cost per 

product 

Replace IP8 air transfer tubes .......................... 2 work-hours × $85 per hour = $170 ....................................... $7,600 $7,700 

Replace HP3 air transfer tubes ........................ 2 work-hours × $85 per hour = $170 ....................................... 11,900 12,070 

Replace front bearing housing IP8 air feed 

tubes.

2 work-hours × $85 per hour = $170 ....................................... 10,000 10,170 

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.
