Discussion The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to certain serial-numbered Daher Aerospace type certificate previously held by SOCATA Model TBM 700
airplanes. The NPRM published in the Federal Register on September 14, 2021
86 FR 51033. The NPRM was prompted by MCAI originated by the European Union Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 20190306, dated December 18, 2019 referred to after this as the MCAI, to address the unsafe condition on certain serialnumbered Daher Aerospace formerly SOCATA Model TBM 700 airplanes.
The MCAI states:
It has been determined that, in certain conditions, an affected switch dump switch part number 7388475012 without a seal may eject from its slot. Investigations identified the root cause in a non-conformity of the affected switch.
This condition, if not corrected, could, in case of smoke/fumes in the cabin, prevent evacuation of the smoke/fumes, possibly resulting in excessive flight crew workload and/or injury to aeroplane occupants.
To address this potential unsafe condition, DAHER AEROSPACE issued the service bulletin SB to provide modification instructions.
For the reasons described above, this EASA AD requires modification of the affected parts by installation of a seal, and introduces requirements for installation of a dump switch.

Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
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 FAAs bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information 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 these products. This AD is adopted as proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Daher Aerospace Service Bulletin SB 7027121, Revision 1, dated November 2019. The service information contains procedures for modifying each dump switch part number 7388475012 by removing the two indicator light units, installing a seal, installing a thin layer of grease, and installing the two indicator lights.
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.
Costs of Compliance The FAA estimates that this AD
affects 150 airplanes of U.S. registry.
The FAA also estimates that it would take about 1 work-hour per airplane and require parts costing $800 to comply with the modification required by this AD. The average labor rate is $85 per work-hour.
Based on these figures, the FAA
estimates the inspection cost of this AD
on U.S. operators to be $132,750 or $885
per airplane.
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.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs authority to issue rules on aviation safety. Subtitle I,
PO 00000

Frm 00004

Fmt 4700

Sfmt 4700

section 106, describes the authority of the FAA Administrator. Subtitle VII:
Aviation Programs, describes in more detail the scope of the Agencys 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.
