Certificate Previously Held by 328 Support Services GmbH; AvCraft 
Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Deutsche Aircraft GmbH Model 328-100 airplanes. This AD was prompted by 
a report of finding cracks in fuselage frames (FR) 24 and FR26. This AD 
requires 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 a 
European Union 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 December 26, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 26, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2023-1707; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The

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 
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 21 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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

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

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
