Airworthiness Directives; Deutsche Aircraft GmbH (Type 
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: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Deutsche Aircraft GmbH Model 328-100 and 328-300 airplanes. 
This proposed AD was prompted by a manufacturer's design review, which 
identified a potential risk of the rudder control rod buckling during 
operation with one engine inoperative during take-off and landing 
phases. This proposed AD would require visually inspecting the rudder 
control rod, performing a one-time functional check of the rudder 
control rod, performing corrective actions if necessary, and reporting 
the inspection results, as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is proposed for incorporation by 
reference (IBR). This proposed AD would also limit the installation of 
affected parts under certain conditions. The FAA is proposing this AD 
to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by October 30, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2023-0065, dated March 20, 2023 
(EASA AD 2023-0065) (also referred to as the MCAI), to correct an 
unsafe condition for 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 MCAI states that during a design review of the 
rudder control architecture, it was discovered that the rudder control 
rod could buckle during operation with one engine inoperative during 
take-off and landing phases. This condition, if not detected and 
corrected, could result in reduced control of the airplane.
    The FAA is proposing 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-2023-1881.

Related Service Information Under 1 CFR Part 51

    EASA AD 2023-0065 specifies procedures for a functional check and 
general visual inspection (GVI) of the rudder control rod (measuring 
the length of the rudder control rod, inspecting for signs of bending, 
ensuring both rudder control rod ends are symmetrically adjusted, and 
ensuring the threads of the rod end fully cover both inspection holes). 
Depending on the inspection results, EASA AD 2023-0065 also specifies 
corrective action, including obtaining and following instructions if 
any discrepancy is identified. EASA AD 2023-0065 also requires 
reporting the inspection results to Deutsche Aircraft GmbH and limits 
the installation of affected parts under certain conditions.
    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 ADDRESSES section.

FAA's Determination

    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 is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2023-0065 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2023-0065 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0065 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Using common terms that are the same as the heading 
of a particular section in EASA AD 2023-0065 does not mean that 
operators need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2023-
0065. Service information required by EASA AD 2023-0065 for compliance 
will be available at regulations.gov under Docket No. FAA-2023-1881 
after the FAA final rule is published.

Interim Action

    The FAA considers that this proposed AD would be 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, if adopted as proposed, would 
affect 54 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

[[Page 63038]]



                                      Estimated Costs for Required Actions

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

2 work-hours x $85 per hour = $170...........................              $0             $170           $9,180
----------------------------------------------------------------------------------------------------------------

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
