Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2013–0104R3, dated February 20, 2024 (also referred to as the MCAI), to correct an unsafe condition on all DAHER AEROSPACE Model TBM 700 airplanes that do not have DAHER Modification (MOD) 70–0777–27 embodied in production. The MCAI states that wear of the inner flap actuator drive nut was detected, which could result in improper play between the actuator threaded rod and the drive nut with potential loss of flap control and consequent reduced or loss of control of the airplane. The MCAI requires cleaning and lubricating the internal actuator rods, measuring the play between the drive nuts and the internal actuator rods, and if any play is found, replacing the drive nuts. The MCAI also allows replacing the drive nuts with newly designed drive nuts as terminating action for the repetitive cleaning, lubricating, and measuring for play. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–2321. Material Incorporated by Reference Under 1 CFR Part 51 The FAA reviewed Daher Aerospace Service Bulletin SB 70–118 Revision 3, dated December 2023. This material specifies procedures for cleaning and lubricating the internal actuator rods, measuring the play between the drive nut and the internal actuator rods, and replacing the drive nut. 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. FAA’s Determination 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 and material referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the material already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 807 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ddrumheller on DSK120RN23PROD with PROPOSALS1 ESTIMATED COSTS Action Labor cost Clean and lubricate left-hand (LH) and right-hand (RH) internal actuator rods. Measure the play for the LH and RH drive nuts. 1 work-hour × $85 per hour = $85, per cleaning and lubricating cycle. 1 work-hour × $85 per hour = $85, per measurement cycle. If, during any proposed measurement for play, no discrepancy is found, operators have the option to replace the LH and RH drive nuts.

The FAA estimates the E:\FR\FM\30SEP1.SGM 30SEP1 Federal Register / Vol. 89, No. 189 / Monday, September 30, 2024 / Proposed Rules 79487 following costs for replacing the LH and RH drive nuts: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Replace drive nuts ........................................................ 4 work-hours × $85 per hour = $340 ........................... $200 $540 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. ddrumheller on DSK120RN23PROD with PROPOSALS1 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: VerDate Sep<11>2014 16:41 Sep 27, 2024 Jkt 262001 PART 39—AIRWORTHINESS DIRECTIVES 1.

Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2013-0104R3, dated February 20, 2024 (also referred to as the 
MCAI), to correct an unsafe condition on all DAHER AEROSPACE Model TBM 
700 airplanes that do not have DAHER Modification (MOD) 70-0777-27 
embodied in production. The MCAI states that wear of the inner flap 
actuator drive nut was detected, which could result in improper play 
between the actuator threaded rod and the drive nut with potential loss 
of flap control and consequent reduced or loss of control of the 
airplane. The MCAI requires cleaning and lubricating the internal 
actuator rods, measuring the play between the drive nuts and the 
internal actuator rods, and if any play is found, replacing the drive 
nuts. The MCAI also allows replacing the drive nuts with newly designed 
drive nuts as terminating action for the repetitive cleaning, 
lubricating, and measuring for play.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2321.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed Daher Aerospace Service Bulletin SB 70-118 
Revision 3, dated December 2023. This material specifies procedures for 
cleaning and lubricating the internal actuator rods, measuring the play 
between the drive nut and the internal actuator rods, and replacing the 
drive nut. 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.

FAA's Determination

    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 and material referenced above. The FAA is issuing this NPRM 
after determining that the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the material already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 807 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

the LH and RH drive nuts must be replaced. Replacing the LH and RH 
drive nuts would be terminating action for the proposed repetitive 
cleaning, lubricating, and measuring play. The FAA estimates the

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

(d) Subject

    Joint Aircraft System Component (JASC) Code 2750, TE Flap 
Control System; 2752, TE Flap Actuator.

(e) Unsafe Condition

    This AD was prompted by reports of wear of the inner flap 
actuator drive nut. The FAA is issuing this AD to prevent wear of 
the drive nut threading on the internal actuator flaps. The unsafe 
condition, if not addressed, could result in improper play between 
the actuator threaded rod and the drive nut, which could result in 
loss of flap control, resulting in reduced or loss of control of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    (1) Clean and lubricate the left-hand (LH) and right-hand (RH) 
inner actuator rods in accordance with Paragraph C. in the 
Description of Accomplishment Instructions of Daher Aerospace 
Service Bulletin SB 70-118 Revision 3, dated December 2023 (Daher SB 
70-118) within the compliance times identified in paragraph 
(g)(1)(i) or (ii) of this AD, whichever occurs later.
    (i) Before the accumulation of 400 hours time-in-service (TIS) 
or 12 months, whichever occurs first, since the first installation 
of a LH and RH inner flap actuator, and thereafter at intervals not 
to exceed 400 hours TIS or 12 months, whichever occurs first.
    (ii) Within 10 hours TIS after the effective date of this AD and 
thereafter at intervals not to exceed 400 hours TIS or 12 months, 
whichever occurs first.
    (2) Within the compliance time identified in paragraph (g)(2)(i) 
or (ii) of this AD, whichever occurs later, and thereafter, at 
intervals not to exceed 400 hours TIS or 12 months, whichever occurs
