RIN 2120-AA64
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 reports of a broken attachment eyebolt in a Collins Aerospace JB6
Commuter Class passenger seat. This proposed AD would require a one-time detailed
inspection of each affected part, and applicable corrective actions, and would also limit
the installation of affected parts, as specified in a European Union Aviation Safety
Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 [INSERT DATE 45
DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER].

Background
EASA, which is the Technical Agent for the Member States of the European
Union, has issued EASA AD 2024-0051, dated February 23, 2024 (EASA AD

2024-0051) (also referred to as the MCAI), to correct an unsafe condition for all
Deutsche Aircraft GmbH Model 328-100 and 328-300 airplanes. The MCAI states there
have been reports of a broken attachment eyebolt in a Collins Aerospace JB6 Commuter
Class passenger seat. The eyebolt is the connection between the reclining mechanism and
the seat structure and connects the seat belt to the seat structure. Broken attachment
eyebolts, if not detected and corrected, could prevent the correct operation of the safety
belts, possibly resulting in injuries to seat occupants.
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-2024-1889.
Related Material Under 1 CFR Part 51
EASA AD 2024-0051 specifies a one-time detailed inspection of affected eyebolt
and spreader for correct installation and discrepancies (i.e., cracks, traces of aluminum
flakes or remainders of ripped-out threads in the tip threads, and damaged thread runs),
and applicable corrective actions (obtaining and following repair instructions and
replacing the affected parts). EASA AD 2024-0051 also specifies an affected part may be
installed provided, before installation, that part passed an inspection (no damage
detected).
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 2024-0051 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 2024-0051 by reference in the FAA final
rule. This proposed AD would, therefore, require compliance with EASA AD 2024-0051
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 2024-0051 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 2024-0051. Service information required by EASA AD
2024-0051 for compliance will be available at regulations.gov under Docket No. FAA2024-1889 after the FAA final rule is published.
Interim Action
The FAA considers that this proposed AD would be an interim action. The FAA
anticipates that further AD action will follow.

Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would affect 30
airplanes of U.S. registry. The FAA estimates the following costs to comply with this
proposed AD:
Estimated costs for required actions
Labor cost

Parts cost

Cost per product

Cost on U.S. operators

12 work-hours X
$85 per hour =
$1,020

$0

$1,020

$30,600

The FAA estimates the following costs to do any necessary on-condition action
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 this on-condition action:
Estimated costs of on-condition actions
Labor cost

Parts cost

Cost per product

0 work-hour X $85 per hour =
$0

$1,126

$1,126

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