ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Canada Limited Partnership 

Model BD–500–1A10 and BD–500– 

1A11 airplanes. This AD was prompted 

by reports of wear damage found 

between the bonding clamps and the 

fuel feed tubes inside the left- and righthand fuel tanks. This AD requires 

repetitive inspections of the fuel feed 

tubes for damage, replacement if 

necessary, and modification of the fuel 

feed line installation inside the left- and 

right-hand fuel tanks, which would 

terminate the repetitive inspections, as 

specified in a Transport Canada Civil 

Aviation (TCCA) AD, which is 

incorporated by reference. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 15,

SUPPLEMENTARY INFORMATION: 

Background 

TCCA, which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2019–19R1, issued November 1, 2019 

(TCCA AD CF–2019–19R1) (also 

referred to as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Airbus Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. The NPRM 

published in the Federal Register on 

May 28, 2021 (86 FR 28719). The NPRM 

was prompted by reports of wear 

damage found between the bonding 

clamps and the fuel feed tubes inside 

the left- and right-hand fuel tanks. The 

NPRM proposed to require repetitive 

inspections of the fuel feed tubes for 

damage, replacement if necessary, and 

modification of the fuel feed line 

installation inside the left- and righthand fuel tanks, which would terminate 

the repetitive inspections, as specified 

in TCCA AD CF–2019–19R1. 

The FAA is issuing this AD to address 

failure of certain fuel feed tubes, which 

could lead to a severe fuel imbalance or 

fuel starvation of one engine, or in the 

event of the failure of multiple fuel 

tubes feeding both engines, could result 

in an in-flight shutdown of both 

engines. See the MCAI for additional 

background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

The FAA received an additional 

comment from Delta Air Lines (DAL). 

The following presents the comment 

received on the NPRM and the FAA’s 

response. 

Request for an Optional Method of 

Compliance 

DAL asked that the FAA add an 

optional method of compliance to the 

proposed AD. DAL recommended an 

additional exception be added in 

paragraph (h)(5) of the proposed AD to 

specify that: ‘‘It is acceptable to 

accomplish Airbus Canada Limited 

Partnership Service Bulletin BD500– 

282004, Issue No. 001, dated August 30, 

2019, concurrently with Airbus Canada 

Limited Partnership Service Bulletin 

BD500–282005, Issue No. 001, dated 

August 30, 2019, as terminating action 

for Part I and Part II of TCCA AD CF– 

2019–19R1.’’ DAL stated that Airbus 

Canada Limited Partnership Service 

Bulletin BD500–282005 (which is not 

required by the proposed AD) also 

modifies the fuel feed system. DAL 

noted that doing the service bulletins 


khammond on DSKJM1Z7X2PROD with RULES
7028 Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Rules and Regulations 

concurrently would require reordering 

and eliminating steps from the service 

information. DAL stated that these 

changes would not alter the final 

configuration of Airbus Canada Limited 

Partnership Service Bulletin BD500– 

282004, Issue No. 001, dated August 30, 

2019. DAL noted the changes simply 

allow these modifications to be done 

concurrently. DAL concluded that both 

service bulletins are FAA approved. 

The FAA disagrees with the 

commenter’s request. An operator may 

always do additional work while 

performing tasks required by an AD 

without the need for an exemption or an 

alternate method of compliance 

(AMOC), as long as those tasks do not 

impact compliance with the AD. 

However, in this case, DAL is proposing 

to reorder or eliminate certain steps in 

the required service information. 

Although DAL provided some 

information, it did not provide 

sufficient data to allow the FAA to 

conclusively determine that the 

proposed changes would provide an 

acceptable level of safety. In addition, 

the FAA does not consider it 

appropriate to include provisions in an 

AD applicable only to a single operator’s 

unique use of required service 

information. However, under the 

provisions of paragraph (j)(1) of this AD, 

the FAA will consider requests for an 

AMOC. Therefore, the FAA has not 

changed this AD in this regard. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Related Service Information Under 1 

CFR Part 51 

TCCA AD CF–2019–19R1 describes 

procedures for repetitive inspections of 

the fuel feed tubes for damage, 

replacement if any damage is found, and 

modification of the fuel feed line 

installation inside the left- and righthand fuel tanks, which would terminate 

the repetitive inspections. 

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 the ADDRESSES section. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking then. 

Costs of Compliance 

The FAA estimates that this AD 

affects 46 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Up to 91 work-hours × $85 per hour = Up to $7,735 ..... Up to $15,265 .................... Up to $23,000 .................... Up to $1,058,000. 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need these 

on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

3 work-hours × $85 per hour = $255 ...................................................... Up to $77,000 ................................ Up to $77,255. 

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.

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701.

damage found between the bonding clamps 

and the fuel feed tubes inside the left- and 

right-hand fuel tanks. In one incident, the 

wear damage resulted in a hole in the main 

engine fuel feed tube located in the collector 

tank, and subsequent fuel imbalance during 

flight. The FAA is issuing this AD to address 

failure of certain fuel feed tubes, which could 

lead to a severe fuel imbalance or fuel 

starvation of one engine, or in the event of 

the failure of multiple fuel tubes feeding both 

engines, could result in an in-flight 

shutdown of both engines. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, TCCA AD CF–2019–19R1. 

(h) Exceptions to TCCA AD CF–2019–19R1 

(1) Where TCCA AD CF–2019–19R1 refers 

to the effective date of TCCA AD CF–2019– 

19 (May 27, 2019), this AD requires using the 

effective date of this AD.

Airworthiness Directives; International 

Aero Engines AG Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2021–11– 

15 for certain International Aero 

Engines AG (IAE) V2500 model turbofan 

engines. AD 2021–11–15 required 

performance of an ultrasonic inspection 

(USI) of the high-pressure turbine (HPT) 

1st-stage disk and HPT 2nd-stage disk 

and, depending on the results of the 

inspections, replacement of the HPT 1ststage disk or HPT 2nd-stage disk. Since 

the FAA issued AD 2021–11–15, the 

FAA determined the need to clarify the 

compliance time for inspection of any 

HPT 1st-stage disk or HPT 2nd-stage 

disk that is installed on a low-thrust 

model engine but had been previously 

operated on a high-thrust model engine. 

This AD requires performance of a USI 

of the HPT 1st-stage disk and HPT 2ndstage disk and, depending on the results 

of the inspections, replacement of the 

HPT 1st-stage disk or HPT 2nd-stage 

disk. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective March 15, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 15, 2022.
