information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as baggage nets 
installed with defective buckles, which may result in failure of the 
baggage net to restrain the baggage or cargo, which could lead to 
injury to the occupants in the case of an emergency landing. This AD 
requires identifying and replacing the affected part. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective August 11, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 11, 
2022.

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 Diamond Aircraft 
Industries Inc. Model DA 40, DA 40 F, and DA 40 NG airplanes. The NPRM 
published in the Federal Register on April 8, 2022 (87 FR 20781). The 
NPRM was prompted by MCAI originated by Transport Canada, which is the 
aviation authority for Canada. Transport Canada issued AD CF-2021-24, 
dated July 21, 2021 (referred to after this as ``the MCAI''), to 
address an unsafe condition on all Diamond Aircraft Industries Inc. 
Model DA 40, DA 40 D, DA 40 F, DA 40 NG, and DA 62 airplanes. The MCAI 
states:

    Diamond Aircraft Industries Inc. (DAI) has received reports of 
defective buckles installed as part of the baggage nets on DA 40 NG 
and DA 62 aeroplanes. An investigation revealed a quality escape in 
the manufacturing of the Quick Fix Baggage Net Assembly, part number 
(P/N) D44-2550-90-00 and P/N D67-2550-90-00_02, by the supplier. P/N 
D44-2550-90-00 baggage nets can also be installed on DA 40, DA 40 D 
and DA 40 F aeroplanes. The baggage nets installed with defective 
buckles may not maintain sufficient holding force to restrain the 
baggage or cargo that is carried in the same compartment as 
passengers, and consequently, may not provide adequate means to 
protect the passengers from injury.
    This condition, if not corrected, could result in the failure of 
the baggage net to restrain the baggage or cargo, which could lead 
to injury to the occupants in the case of an emergency landing.
    DAI undertook a voluntary campaign to replace all defective 
Quick Fix Baggage Net Assemblies. However, DAI was unable to 
complete the campaign in its entirety, and therefore, a number of 
aeroplanes with defective baggage nets that have not yet been 
replaced, remain in operation.
    As a result, DAI issued Mandatory Service Bulletin (MSB) 40-093, 
MSB D4-110, MSB F4-039, MSB 40NG-065 and MSB 62-028, providing 
accomplishment instructions to replace the defective Quick Fix 
Baggage Net Assemblies.
    This [Transport Canada] AD mandates the removal and replacement 
of the affected baggage nets. This [Transport Canada] AD also 
renders any affected baggage nets not eligible for installation as a 
replacement part on DA 40, DA 40 D, DA 40 F, DA 40 NG and DA 62 
aeroplanes.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2022-
0450.
    In the NPRM, the FAA proposed to require identifying and replacing 
affected baggage nets. The FAA is issuing this AD to prevent failure of 
the baggage net to restrain the baggage or cargo. This unsafe 
condition, if not corrected, could result in injury to occupants in the 
case of an emergency landing.

Discussion of Final Airworthiness Directive

Comments

    The FAA received one comment on the NPRM from an individual. The 
commenter supported the NPRM without change.

Conclusion

    These products have been approved by the 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, it has notified the FAA of the unsafe condition described in 
the MCAI referenced above. The FAA reviewed the relevant data, 
considered the comment 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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed the following service information issued by 
Diamond Aircraft Industries Inc., which specify procedures for 
identifying, removing, and replacing the affected baggage nets.
     Mandatory Service Bulletin No. MSB 40-093, Rev. 0, dated 
July 6, 2021.
     Mandatory Service Bulletin No. MSB F4-039, Rev. 0, dated 
July 6, 2021.
     Mandatory Service Bulletin No. MSB 40NG-065, Rev. 1, dated 
July 6, 2021.
    These documents are distinct since they apply to different airplane 
models.
    This service information 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 or Service Information

    The MCAI applies to Diamond Aircraft Industries Inc. Model DA 40, 
DA 40 D, DA 40 F, DA 40 NG, and DA 62 airplanes. This AD does not apply 
to Model DA 62 airplanes. The FAA plans to address Model DA 62 
airplanes in future rulemaking.
    In addition, the MCAI applies to the Model DA 40 D airplanes and 
this AD does not because it does not have an FAA type certificate.

Costs of Compliance

    The FAA estimates that this AD affects 800 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this 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

    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 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.
