SUPPLEMENTARY INFORMATION: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Deutsche Aircraft GmbH (Type Certificate previously held by 328 Support Services GmbH; AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328–100 and 328–300 airplanes. The NPRM published in the Federal Register on December 6, 2023 (88 FR 84764). The NPRM was prompted by AD 2023–0137, dated July 12, 2023 (EASA AD 2023–0137) (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 operators reported findings of damaged affected parts. The extent of the detected damage of the affected parts did not ensure that appropriately low electrical impedance is obtained and maintained through the affected bonding path. The unsafe condition, if not detected and corrected, could lead to the loss of bonding function and, in combination with a lightning strike, create a source of PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 17723 ignition in a fuel tank, possibly resulting in a fire or explosion. In the NPRM, the FAA proposed to require a one-time detailed inspection of each affected part, and applicable corrective actions, as specified in EASA AD 2023–0137. 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–2023–2230. 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 This product has been approved by the aviation authority of another country and is 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 and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. 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. Related Service Information Under 1 CFR Part 51 EASA AD 2023–0137 specifies procedures for a one-time detailed inspection of each affected part for worn and ruptured bonding straps, and applicable corrective actions (replacing the affected parts). 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 that this AD is an 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 35 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\12MRR1.SGM 12MRR1 17724 Federal Register / Vol. 89, No. 49 / Tuesday, March 12, 2024 / Rules and Regulations ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 44 work-hours × $85 per hour = $3,740 ..................................................................................... $0 $3,740 $130,900 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.

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 Deutsche Aircraft 
GmbH (Type Certificate previously held by 328 Support Services GmbH; 
AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) 
Model 328-100 and 328-300 airplanes. The NPRM published in the Federal 
Register on December 6, 2023 (88 FR 84764). The NPRM was prompted by AD 
2023-0137, dated July 12, 2023 (EASA AD 2023-0137) (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 operators reported 
findings of damaged affected parts. The extent of the detected damage 
of the affected parts did not ensure that appropriately low electrical 
impedance is obtained and maintained through the affected bonding path. 
The unsafe condition, if not detected and corrected, could lead to the 
loss of bonding function and, in combination with a lightning strike, 
create a source of ignition in a fuel tank, possibly resulting in a 
fire or explosion.
    In the NPRM, the FAA proposed to require a one-time detailed 
inspection of each affected part, and applicable corrective actions, as 
specified in EASA AD 2023-0137. 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-2023-2230.

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

    This product has been approved by the aviation authority of another 
country and is 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 and determined 
that air safety requires adopting this AD as proposed. Accordingly, the 
FAA is issuing this AD to address the unsafe condition on this product. 
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.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0137 specifies procedures for a one-time detailed 
inspection of each affected part for worn and ruptured bonding straps, 
and applicable corrective actions (replacing the affected parts). 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 that this AD is an 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 35 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------

    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:
    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in this AD.

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2024-03-07 Deutsche Aircraft GmbH (Type Certificate Previously Held 
by 328 Support Services GmbH; AvCraft Aerospace GmbH; Fairchild 
Dornier GmbH; Dornier Luftfahrt GmbH): Amendment 39-22677; Docket 
No. FAA-2023-2230; Project Identifier MCAI-2023-00861-T.

(a) Effective Date

    This airworthiness directive (AD) is effective April 16, 2024.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Deutsche Aircraft GmbH (Type Certificate 
previously held by 328 Support Services GmbH; AvCraft Aerospace 
GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 
and 328-300 airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Unsafe Condition

    This AD was prompted by operator reports of worn and ruptured 
bonding straps inside the feeder wing tanks and in both outer and 
inner wing tanks. The FAA is issuing this AD to address damaged 
bonding straps. The unsafe condition, if not addressed, could result 
in the loss of bonding function and, in combination with a lightning 
strike, create a source of ignition in a fuel tank, possibly 
resulting in a fire or explosion and consequent loss of the 
airplane.

(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, European Union Aviation Safety Agency (EASA) AD 
2023-0137, dated July 12, 2023 (EASA AD 2023-0137).

(h) Exceptions to EASA AD 2023-0137

    (1) Where EASA AD 2023-0137 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) This AD does not adopt the ``Remarks'' section of EASA AD 
2023-0137.
    (3) Where paragraph (2) of EASA AD 2023-0137 specifies if ``any 
damage is detected as defined in the ASB,'' this AD requires 
replacing those words with ``any worn or ruptured bonding strap is 
detected.''

(i) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Validation Branch, FAA, has the authority to approve

to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Validation Branch, FAA; or EASA; or Deutsche Aircraft GmbH's EASA 
Design Organization Approval (DOA). If approved by the DOA, the
