AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–13– 

07 for all Rolls-Royce Deutschland Ltd 

& Co KG (RRD) Trent 1000–D2, Trent 

1000–J2, and Trent 1000–K2 model 

turbofan engines with a certain partnumbered fuel pump installed. AD 

2020–13–07 required removal and 

replacement of the fuel pump with a 

part eligible for installation. This AD 

was prompted by the manufacturer’s 

investigation into an unexpected 

reduction in fuel pump performance in 

certain high life fuel pumps and 

subsequent determination that an 

additional part-numbered fuel pump is 

subject to the same unsafe condition. 

This AD requires new and reduced life 

limits for certain part-numbered fuel 

pumps, depending on the engine model 

the fuel pump is installed on. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective October 13, 

2021. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–13–07, 

Amendment 39–21152 (85 FR 38312, 

June 26, 2020), (AD 2020–13–07). AD 

2020–13–07 applied to all RRD Trent 

1000–D2, Trent 1000–J2, and Trent 

1000–K2 model turbofan engines with 

fuel pump, part number G5030FPU01, 

installed. The NPRM published in the 

Federal Register on March 30, 2021 (86 

FR 16548). The NPRM was prompted by 

the manufacturer’s investigation into an 

unexpected reduction in fuel pump 

performance in certain high life fuel 

pumps and life-related wear-out of the 

internal components and subsequent 

determination that an additional partnumbered fuel pump is subject to this 

same unsafe condition. In the NPRM, 

the FAA proposed to retain all the 

requirements of AD 2020–13–07. In the 

NPRM, the FAA also proposed to add an 

additional part-numbered fuel pump 

and additional Trent 1000 model 

turbofan engines on which this fuel 

pump is installed to the applicability. In 

the NPRM, the FAA also proposed to 

require new and reduced life limits for 

certain part-numbered fuel pumps, 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Rules and Regulations 50231 

depending on the engine model the fuel 

pump is installed on. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community, has issued EASA 

AD 2021–0006, dated January 7, 2021 

(referred to after this as ‘‘the MCAI’’), to 

address the unsafe condition on these 

products. The MCAI states: 

An unexpected reduction in fuel pump 

performance has been seen during testing of 

high life units. Strip examination of these 

fuel pumps has identified that life related 

wear-out of the internal components is 

causing deterioration in pump efficiency. 

The effect of the loss of fuel pump efficiency 

is more pronounced on higher rated engines. 

This condition, if not corrected, could lead 

to reduced engine thrust, possibly resulting 

in reduced control of the aeroplane. 

To address this potential unsafe condition, 

Rolls-Royce published NMSB 73–AK581 

(original issue) to provide instructions for 

replacement of the affected parts before 

exceeding reduced life limits. Consequently, 

EASA issued AD 2020–0124 to require the 

removal from service of the affected parts. 

After that [EASA] AD was issued, RollsRoyce issued NMSB 73–AK581 Revision 1, 

introducing an additional fuel pump, P/N 

TPS1000–05, as well as new and reduced life 

limits for the affected parts, depending on 

engine model (rating). Consequently, EASA 

issued AD 2020–0154, retaining the 

requirements of EASA AD 2020–0124, which 

was superseded, expanding the Applicability 

to include additional engine models (ratings) 

and requiring implementation of the new and 

reduced life limits. 

Since that [EASA] AD was issued, RollsRoyce issued the NMSB, as defined in this 

[EASA] AD, introducing new and reduced 

life limits for the affected parts, depending 

on engine model (rating). 

For the reason described above, this 

[EASA] AD retains the requirements of EASA 

AD 2020–0154, which is superseded, and 

requires implementation of the new and 

reduced life limits, as applicable. 

You may obtain further information 

by examining the MCAI in the AD 

docket on https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2021–0198. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two commenters. The commenters were 

The Boeing Company (Boeing) and 

Rolls-Royce. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Request To Update Service Bulletin 

Boeing and Rolls-Royce requested that 

the FAA update the specified service 

information by referencing Revision 3 of 

Rolls-Royce (RR) Alert NonModification Service Bulletin (NMSB) 

TRENT 1000–73–AK581. 

The FAA agrees and has updated this 

AD to reference RR Alert NMSB TRENT 

1000–73–AK581, Revision 3, dated 

April 7, 2021. This change to this AD 

imposes no additional burden on 

operators. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for minor editorial 

changes and any other changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed RR Alert NMSB 

TRENT 1000–73–AK581, Revision 3, 

dated April 7, 2021 (RR Alert NMSB). 

The RR Alert NMSB introduces a 

reduced life limit for affected fuel 

pumps installed on certain RRD Trent 

1000 model turbofan engines. The RR 

Alert NMSB also includes additional 

RRD Trent 1000 turbofan engine models 

that require implementation of the 

reduced life limits for affected fuel 

pumps. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in 

ADDRESSES. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking. 

Costs of Compliance 

The FAA estimates that this AD 

affects 28 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 

Replace fuel pump .......................................... 3 work-hours × $85 per hour = $255 ............. $393,552 $393,807 $11,026,596 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this AD may be covered under 

warranty, thereby reducing the cost 

impact on affected individuals. 

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 

The FAA has determined that 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.
