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 DAI Model DA 42, DA
42 NG, and DA 42 M-NG airplanes. The NPRM was published in the Federal
Register on August 25, 2025 (90 FR 41346). The NPRM was prompted by
EASA AD 2024-0235, dated December 6, 2024 (EASA AD 2024-0235) (also
referred to as the MCAI), issued by the European Union Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Union. The MCAI states that DAI
[[Page 559]]
received several reports of passenger door separation. DAI attributed
the root cause of certain instances to the passenger doors not being
properly latched, but DAI was unable to find a definitive root cause of
the remaining occurrences. Passenger door separation could damage the
airplane, which could lead to loss of control of the airplane and
injury to people on the ground. To address the unsafe condition, DAI
issued an AFM temporary revision amending procedures and limitations
and issued material with instructions to install placards in the cabin
to prevent misuse of the passenger door, to inspect the passenger door
latching and safety hook mechanisms, and to collect and report findings
after each repetitive inspection to them.
In the NPRM, the FAA proposed to require revising the existing AFM
for your airplane to provide the flight crew with revised operating
limitations, emergency procedures, and normal operating procedures;
modifying the airplane; and repetitively inspecting the door latching
and safety hooks for correct engagement, foreign objects, damage
(including but not limited to corrosion and wear that exceeds specified
limits), and proper function. The FAA is issuing this AD to address the
unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2025-2263.
Discussion of Final Airworthiness Directive
Comments
The FAA received one comment from an individual commenter. The
commenter supported the NPRM without change.
Conclusion
These products have been approved by the civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA reviewed the relevant
data, considered any comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. This AD is
adopted as proposed in the NPRM.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Diamond Aircraft Mandatory Service Bulletin MSB
42-149 and MSB 42NG-095, dated December 2, 2024 (issued as one
document), published with Diamond Aircraft Work Instruction WI-MSB 42-
149 and WI-MSB 42NG-095, Revision 2, dated January 17, 2025 (issued as
one document), attached. This material specifies procedures for
installing passenger door placards and inspecting the passenger door
system for Model DA 42, DA 42 M, DA 42 NG, and DA 42 M-NG airplanes.
The FAA also reviewed Diamond Aircraft Temporary Revision TR-MAM-
42-1333, for the DA 42 Airplane Flight Manual (AFM), Doc. No. 7.01.05-
E, dated November 28, 2024. This material specifies procedures for
revising the operating limitations, emergency procedures, and normal
operating procedures related to door latching and locking for Model DA
42 airplanes with Continental Aerospace Technologies engines installed.
In addition, the FAA reviewed Diamond Aircraft Temporary Revision
TR-MAM-42-1333, for the DA 42 with OAM 42-102 Garmin GFC 700 AFM, Doc.
No. 7.01.06-E, dated November 28, 2024. This material specifies
procedures for amending the AFM for Model DA 42 airplanes with
Continental Aerospace Technologies engines and Garmin GFC 700 Automatic
Flight Control System installed.
The FAA also reviewed Diamond Aircraft Temporary Revision TR-MAM-
42-1333, for the DA 42 NG AFM, Doc. No. 7.01.15-E, dated November 28,
2024. This material specifies procedures for revising the operating
limitations, emergency procedures, and normal operating procedures of
the AFM for Model DA 42 NG and DA 42 NG-M airplanes.
The FAA also reviewed Diamond Aircraft Temporary Revision TR-MAM-
42-1333, for the DA 42 NG AFM, Doc. No. 7.01.16-E, dated November 28,
2024. This material specifies procedures for amending the AFM for Model
DA 42 NG and DA 42 NG-M airplanes with MAM 42-600 Performance
Enhancement.
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.
Differences Between This AD and the MCAI
The MCAI applies to DAI Model 42 M airplanes, but this AD does not
include this model because it does not have an FAA type certificate.
The MCAI includes a requirement to inform all flight crews and,
thereafter, operate the airplane. However, this AD does not
specifically require this action based on the following:
<bullet> For the operating limitations: 14 CFR 91.9 requires that
no person may operate a civil aircraft without complying with the
operating limitations specified in the AFM. Therefore, including a
requirement in this AD to operate the airplane according to the revised
AFM would be redundant and unnecessary. Further, compliance with such a
requirement in an AD would be impracticable to demonstrate or track on
an ongoing basis; therefore, a requirement to operate the airplane in
such a manner would be unenforceable.
<bullet> For the emergency procedures and normal operating
procedures: FAA regulations mandate compliance with only the operating
limitations section of the flight manual. The flight manual changes
required by this AD apply to the emergency procedures and normal
procedures section of the existing AFM for your airplane. Furthermore,
compliance with such requirements in an AD is impracticable to
demonstrate or track on an ongoing basis; therefore, a requirement to
operate the aircraft in such a manner is unenforceable. Nonetheless,
the FAA recommends that flight crews of the airplanes listed in the
applicability operate in accordance with the revised emergency
procedures mandated by this AD.
The referenced material specifies to contact DAI for repair
instructions, but this AD requires contacting the Manager,
International Validation Branch, FAA; EASA; or DAI's EASA Design
Organization Approval (DOA) instead.
The MCAI specifies where the temporary revisions provide
instructions to contact the manufacturer, but this AD requires
contacting the Manager, International Validation Branch, FAA; EASA; or
DAI's EASA DOA instead.
The MCAI specifies reporting inspection results within 7 days after
accomplishing any inspection, but this AD requires reporting inspection
results within 30 days after accomplishing any inspection.
Interim Action
The FAA considers that this AD is an interim action. This unsafe
condition is still under investigation by the manufacturer and,
depending on the results of that investigation, the FAA may consider
further rulemaking action.
Costs of Compliance
The FAA estimates that this AD affects 222 airplanes of U.S.
registry.
[[Page 560]]
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
AFM revision..................... 1 work-hour x $85 $0 $85................. $18,870
per hour = $85.
Initial inspection............... 3 work-hours x $85 0 $255................ $56,610
per hour = $255.
Repetitive inspections........... 1 work-hour x $85 0 $85 (each inspection $18,870 (each
per hour = $85 cycle). inspection cycle)
(each inspection
cycle).
Placard installation............. 1 work-hour x $85 25 $110................ $24,420
per hour = $85.
Inspection results reporting..... 1 work-hour x $85 0 $85 (each cycle).... $18,870 (each cycle)
per hour = $85
(each cycle).
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspections. The agency has no way of determining the number of
airplanes that might need these replacements:
On-Condition Costs
------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
------------------------------------------------------------------------
Safety hook replacement...... 1 work-hour x $306 $391
$85 per hour =
$85.
Safety hook spring 1 work-hour x 8 93
replacement. $85 per hour =
$85.
Retaining bracket replacement 1 work-hour x 185 270
$85 per hour =
$85.
Safety hook actuation pin 1 work-hour x 164 249
replacement. $85 per hour =
$85.
Latching mechanism spring 1 work-hour x 12 97
replacement. $85 per hour =
$85.
Latching bolts replacement... 1 work-hour x 109 194
$85 per hour =
$85.
Gas spring replacement....... 1 work-hour x 312 397
$85 per hour =
$85.
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.
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.
