AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2008–16– 

06, which applied to all BAE Systems 

(Operations) Limited Model 4101 

airplanes. AD 2008–16–06 required the 

installation of additional bonding leads, 

inspection of existing bonding leads for 

defects, inspection of fuel system pipe 

runs in the wings to ensure appropriate 

clearances are maintained, and 

corrective actions. This AD continues to 

require the actions in AD 2008–16–06, 

and adds a requirement to install 

additional bonding leads around the 

crossfeed valve and accomplish a 

resistance check. This AD was 

prompted by a report that there is 

insufficient bonding of the crossfeed 

valve in the fuel tank area. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective August 18, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 18, 2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of September 9, 2008 (73 FR

SUPPLEMENTARY INFORMATION: 

Background 

The Civil Aviation Authority (CAA), 

which is the aviation authority for the 

United Kingdom, has issued CAA AD 

G–2021–0013, dated October 21, 2021 

(also referred to as the MCAI), to correct 

an unsafe condition for all BAE Systems 

(Operations) Limited Model 4101 

airplanes. You may examine the MCAI 

in the AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0461. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2008–16–06, 

Amendment 39–15624 (73 FR 45346, 

August 5, 2008) (AD 2008–16–06). AD 

2008–16–06 applied to all BAE Systems 

(Operations) Limited Model 4101 

airplanes. The NPRM published in the 

Federal Register on April 20, 2022 (87 

FR 23474). The NPRM was prompted by 

a report that there is insufficient 

bonding of the crossfeed valve in the 

fuel tank area. The NPRM proposed to 

continue to require the actions in AD 

2008–16–06, and add a requirement to 

install additional bonding leads around 

the crossfeed valve and accomplish a 

resistance check. The FAA is issuing 

this AD to address insufficient or 

defective bonding in the fuel tank area, 

which, if not corrected, could lead to 

ignition of fuel vapors and subsequent 

fuel tank explosion. See the MCAI for 

additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

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 

BAE Systems (Operations) Limited 

has issued Service Bulletin J41–28–013, 

Revision 2, dated July 8, 2019. This 

service information describes 

procedures for installation of additional 

bonding leads on components within 

the dry bay at Rib 1 on the airplane 

centerline and below the fuselage 

(around the crossfeed valve), a 

resistance check, an inspection of 

existing bonding leads for defects, an 

inspection for clearance of all fuel 

system pipe runs in the wings, and 

corrective actions, as necessary. 

Corrective actions include replacing any 

defective bonding leads and adjusting 

clearances of the fuel system pipe runs. 

This AD also requires BAE Systems

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 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.

Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–03– 

25, which applied to certain Airbus SAS 

Model Airbus SAS Model A318 series 

airplanes; Model A319–111, –112, –113, 

–114, –115, –131, –132, and –133 

airplanes; Model A320–211, –212, –214, 

–216, –231, –232, and –233 airplanes; 

and Model A321–111, –112, –131, –211, 

–212, –213, –231, and –232 airplanes. 

AD 2019–03–25 required repetitive 

inspections of the center and outer wing 

box lower stiffeners and panels at a 

certain junction on the left- and righthand sides for any cracking, and repair 

if necessary. AD 2019–03–25 also 

provided an optional modification, 

which would terminate the repetitive 

inspections. This AD was prompted by 

a determination that, for certain 

airplanes, the compliance time for the 

initial inspection is inadequate and 

must be revised. This AD continues to 

require the actions specified in AD 

2019–03–25 with revised compliance 

times for certain airplanes and 

additional actions for certain airplanes, 

and expands the applicability, as 

specified in a European Aviation Safety 

Agency (EASA) 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 August 18, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 18, 2022.
