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 Model 328–100 airplanes. The NPRM published in the Federal Register on August 14, 2023 (88 FR 54939). The NPRM was prompted by AD 2023–0081, dated April 18, 2023, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2023–0081) (also referred to as the MCAI). The MCAI states a report of finding cracks in fuselage frames FR24 and FR26. Investigation of the root cause for cracking is ongoing. This condition, if not detected and corrected, could lead to failure of load carrying structural elements, possibly resulting in reduced integrity of the fuselage. In the NPRM, the FAA proposed to require a one-time detailed and eddy current inspection of fuselage FR24 and FR26 (left and right sides), performing corrective actions if necessary, and reporting the inspection results, as specified in EASA AD 2023–0081. 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–2023–1707. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 Additional Changes to This AD The FAA added paragraph (h)(5) of this AD to clarify that any cracks found during the required inspections must be repaired before further flight. The FAA has determined that, because of the safety implications and consequences associated with that cracking, any cracking in the fuselage FR24 and FR26 must be repaired before further flight. 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 2023–0081 specifies procedures for a one-time detailed and eddy current inspection of fuselage FR24 and FR26 (left and right sides) for damage (cracks). Depending on the inspection results, EASA AD 2023–0081 also specifies corrective action, including obtaining and following instructions for crack repair. EASA AD 2023–0081 also requires reporting the inspection results to Deutsche Aircraft GmbH. 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.

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 Model 328-100 airplanes. The NPRM published in the Federal 
Register on August 14, 2023 (88 FR 54939). The NPRM was prompted by AD 
2023-0081, dated April 18, 2023, issued by EASA, which is the Technical 
Agent for the Member States of the European Union (EASA AD 2023-0081) 
(also referred to as the MCAI). The MCAI states a report of finding 
cracks in fuselage frames FR24 and FR26. Investigation of the root 
cause for cracking is ongoing. This condition, if not detected and 
corrected, could lead to failure of load carrying structural elements, 
possibly resulting in reduced integrity of the fuselage.
    In the NPRM, the FAA proposed to require a one-time detailed and 
eddy current inspection of fuselage FR24 and FR26 (left and right 
sides), performing corrective actions if necessary, and reporting the 
inspection results, as specified in EASA AD 2023-0081. 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-2023-1707.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Additional Changes to This AD

    The FAA added paragraph (h)(5) of this AD to clarify that any 
cracks found during the required inspections must be repaired before 
further flight. The FAA has determined that, because of the safety 
implications and consequences associated with that cracking, any 
cracking in the fuselage FR24 and FR26 must be repaired before further 
flight.

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 2023-0081 specifies procedures for a one-time detailed and 
eddy current inspection of fuselage FR24 and FR26 (left and right 
sides) for damage (cracks). Depending on the inspection results, EASA 
AD 2023-0081 also specifies corrective action, including obtaining and 
following instructions for crack repair. EASA AD 2023-0081 also 
requires reporting the inspection results to Deutsche Aircraft GmbH. 
This material is reasonably available because the interested parties 
have access to it through their normal course of business or by 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.
