ACTION : Final rule. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD–100–1A10 airplanes. This AD was prompted by a report that a design deficiency was discovered which could allow a no-back pawl to be incorrectly installed in a horizontal stabilizer trim actuator (HSTA). This AD requires a check for part number and serial numbers of the HSTA, and if necessary, inspection of the no-back pawl installation, and corrective action. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective July 21, 2023.

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 certain Bombardier, Inc., Model BD–100–1A10 airplanes. The NPRM published in the Federal Register on March 24, 2023 (88 FR 17748). The NPRM was prompted by AD CF–2022– 55, dated September 21, 2022, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that during an unscheduled inspection, a design deficiency was discovered which could allow a no-back pawl to be VerDate Sep<11>2014 15:19 Jun 15, 2023 Jkt 259001 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 E:\FR\FM\16JNR1.SGM 16JNR1 ddrumheller on DSK120RN23PROD with RULES1 39342 Federal Register / Vol. 88, No. 116 / Friday, June 16, 2023 / Rules and Regulations incorrectly installed in an HSTA. The no-back mechanism is a primary means to prevent back driving of the HSTA, and the motor brake assemblies (MBAs) are the secondary means. If this condition is not corrected, a non- functioning no-back mechanism in combination with loss of, or degraded HSTA MBA braking capability, could lead to a loss of control of the airplane. The MCAI also states that as a mitigating action, Transport Canada AD CF–2019–23, dated June 18, 2019, was issued to mandate a software upgrade for the horizontal stabilizer trim electronic control unit to verify the MBA for braking capability during the power up test on certain Bombardier, Inc., Model BD–100–1A10 airplanes. Transport Canada AD CF–2019–23 corresponds to FAA AD 2019–15–04, Amendment 39–19697 (84 FR 38862, August 8, 2019) (AD 2019–15–04). In the NPRM, the FAA proposed to require a check for part number and serial numbers of the HSTA, and if necessary, inspection of the no-back pawl installation, and corrective action. The FAA is issuing 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–2023–0439. Discussion of Final Airworthiness Directive Comments The FAA received comments from an individual who supported the SNPRM/ NPRM without change. Additional Changes to This AD The FAA has revised paragraph (h) of this AD to clarify the parts installation prohibition applies only to any HSTA with P/N C47100–003 or P/N C47100– 004 that does not have either the suffix- K following the serial number or a modification plate showing ‘‘SB C47100–27–02’’ or ‘‘SB C47100–27–03.’’ In the NPRM, the FAA had inadvertently stated that installation of an HSTA with a modification plate showing ‘‘SB C47100–27–02’’ or ‘‘SB C47100–27–03’’ was prohibited. 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 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 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 this product. Except for minor editorial change, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 The FAA reviewed Bombardier Service Bulletins 100–27–20 and 350– 27–009, both Revision 01, both dated December 1, 2020. This service information specifies procedures for a check for part number and serial numbers of the HSTA, and if necessary, inspection of the no-back pawl installation and corrective action. Corrective actions include replacement of the HSTA, and a re-identification and test of the HSTA. These documents are distinct since they apply to different airplane configurations. 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 will affect 703 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E STIMATED C OSTS FOR R EQUIRED A CTIONS Labor cost Parts cost Cost per product Cost on U.S. operators Up to 2 work-hours × $85 per hour = Up to $170 ............................................................. None ................. Up to $170 ....... Up to $119,510. The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of airplanes that might need these on-condition actions: E STIMATED C OSTS OF O N -C ONDITION A CTIONS Labor cost Parts cost Cost per product Up to 25 work-hours × $85 per hour = Up to $2,125 .......................................................................................... $2,905 Up to $5,030. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators. As a result, the FAA has included all known costs in the cost estimate. 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 VerDate Sep<11>2014 15:19 Jun 15, 2023 Jkt 259001 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 E:\FR\FM\16JNR1.SGM 16JNR1 ddrumheller on DSK120RN23PROD with RULES1 39343 Federal Register / Vol. 88, No. 116 / Friday, June 16, 2023 / Rules and Regulations responsibilities among the various levels of government.

ACTION : Final rule. SUMMARY : The FAA is adopting a new airworthiness directive (AD) for certain DAHER AEROSPACE (type certificate previously held by SOCATA) Model TBM 700 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as interference between the emergency exit trim panel and the upholstery panel, which could result in additional effort required to open the emergency exit door. This AD requires modification of the gripping strap, which maintains the upholstery panel on the emergency exit trim panel. The FAA is issuing this AD to address the unsafe condition on these products. DATES : This AD is effective July 21, 2023. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 21, 2023. ADDRESSES : AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2023–0425; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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 certain DAHER AEROSPACE Model TBM 700 airplanes. The NPRM published in the Federal Register on March 8, 2023 (88 FR 14301). The NPRM was prompted by AD 2022–0149, dated July 21, 2022 (referred to after this 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 was prompted by a report that, due to interference between the emergency exit trim panel and the upholstery panel, additional effort may be required to open the emergency exit door. An investigation revealed that the gripping strap, which maintains the upholstery panel on the emergency exit trim panel, is not properly sized. The MCAI requires inserting a temporary revision (TR) into the emergency procedures section of the applicable pilot’s operating handbook (POH), informing all flight crews, operating the airplane accordingly, and modifying the gripping strap, at which time the TR can be removed from the POH. The unsafe condition, if not addressed, could lead to failure of the emergency exit door to perform its intended function during an emergency opening, possibly resulting in reduced evacuation capacity from the airplane and injury to occupants. In the NPRM, the FAA proposed to require modification of the gripping strap, which maintains the upholstery panel on the emergency exit trim panel. The FAA is issuing this AD to address the unsafe condition on these products.
