AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2022–21–15, which applies to certain 

Diamond Aircraft Industries GmbH 

(DAI) Model DA 42, DA 42 NG, and DA 

42 M–NG airplanes. AD 2022–21–15 

requires replacing the rudder T-yoke

axle with an improved rudder T-yoke 

axle. Since the FAA issued AD 2022– 

21–15, the European Union Aviation 

Safety Agency (EASA) superseded its 

mandatory continuing airworthiness 

information (MCAI) to correct an unsafe 

condition on these products. This 

proposed AD would require, for certain 

airplanes, inspecting the rudder steering 

bracket edge distance and depending on 

the inspection results, inspecting the Tyoke bolt hole for wear and play, and 

corrective action if necessary. For 

certain airplanes this proposed AD 

would require replacing the rudder Tyoke bolt (axle) with a serviceable part, 

and applying torque seal marks on the 

rudder T-yoke bolt head, and selflocking nut. For all airplanes this 

proposed AD would require repetitively 

inspecting the torque seal marks on the 

rudder T-yoke bolt head for proper 

alignment and the self-locking nut for 

proper installation and corrective action 

if necessary. This proposed AD would 

also prohibit the installation of affected 

parts. The FAA is proposing this AD to 

address the unsafe condition on these 

products.

Background 

The FAA issued AD 2022–21–15, 

Amendment 39–22214 (87 FR 67541, 

November 9, 2022) (AD 2022–21–15), 

for certain DAI Model DA 42, DA 42 

NG, and DA 42 M–NG airplanes. AD 

2022–21–15 was prompted by MCAI 

originated by EASA, which is the 

Technical Agent for the Member States 

of the European Union. EASA issued 

EASA AD 2019–0302, dated December 

13, 2019 (EASA AD 2019–0302) to 

correct an unsafe condition on DAI 

Model DA 42, DA 42 NG, and DA 42 M– 

NG airplanes. EASA AD 2019–0302 

described the unsafe condition as 

reports of a loose rudder T-yoke axle nut 

on DAI Model DA 42 airplanes and the 

need for new inspections for correct 

installation of the self-locking nut to the 

rudder T-yoke standard bolt LN 9037 

(dimensions M6x90), and depending on 

findings, accomplishment of applicable 

corrective action(s) and replacement of 

the self-locking nut. EASA AD 2019– 

0302 also provided an optional 

terminating action for the repetitive 

inspections. This condition, if not 

detected and corrected, could lead to 

vertical movement of the bolt, possibly 

resulting in reduced rudder control of 

the airplane. 

AD 2022–21–15 requires replacing the 

rudder T-yoke axle with an improved 

rudder T-yoke bolt. The FAA issued AD 

2022–21–15 to prevent movement of the 

T-yoke bolt. 

Actions Since AD 2022–21–15 Was 

Issued 

Since the FAA issued AD 2022–21– 

15, EASA superseded EASA AD 2019– 

0302 and issued EASA AD 2023–0013, 

dated January 18, 2023 (EASA AD 

2023–0013) (referred to after this as the 

MCAI) to correct an unsafe condition on 

all DAI Model DA 42, DA 42 M, DA 42 

NG, and DA 42 M–NG airplanes. 

The MCAI states that since EASA AD 

2019–0302 was issued, DAI published 

revised service information to provide 

additional inspection and modification 

instructions. The MCAI requires a onetime inspection of the rudder steering 

bracket for insufficient edge distance or 

wear, replacement of rudder T-yoke 

standard bolt LN 9037 (dimensions 

M6x90) with rudder T-yoke bolt part 

number (P/N) D60–5320–00–32, 

repetitive inspections of rudder T-yoke 

bolt P/N D60–5320–00–32 for correct 

installation, corrective actions if 

necessary, and prohibits installation of 


lotter on DSK11XQN23PROD with PROPOSALS1
77062 Federal Register / Vol. 88, No. 215 / Wednesday, November 8, 2023 / Proposed Rules 

rudder T-yoke standard bolt LN 9037 

(dimensions M6x90). The affected and 

serviceable parts, identified as ‘‘bolt’’ in 

EASA AD 2023–0013, were referred to 

as ‘‘axle’’ in EASA AD 2019–0302. 

This condition, if not detected and 

corrected, could lead to blockage or loss 

of rudder control. You may examine the 

MCAI in the AD docket at 

regulations.gov under Docket No. FAA– 

2023–2143. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Diamond Aircraft 

Mandatory Service Bulletin DAI MSB 

42–143/1 and DAI MSB 42NG–086/1, 

dated January 25, 2022 (issued as one 

document), published with DAI Work 

Instruction WI–MSB 42–143 and WI– 

MSB 42NG–086, Revision 3, dated 

November 15, 2022 (issued as one 

document) attached. The service 

bulletin specifies compliance with the 

work instruction, which contains 

procedures for inspecting the hole 

position and condition in the rudder 

steering bracket. 

The FAA also reviewed Diamond 

Aircraft Recommended Service Bulletin 

DAI RSB 42–139 and DAI RSB 42NG– 

081, dated October 21, 2019 (issued as 

one document), published with DAI 

Work Instruction WI–RSB 42–139 and 

WI–RSB 42NG–081, Revision 2, dated 

November 15, 2022 (issued as one 

document) attached. The service 

bulletin specifies compliance with the 

work instruction, which contains 

procedures for replacement of the 

rudder T-yoke axle with an improved 

(additional retaining pin) rudder T-yoke 

axle. 

In addition, the FAA reviewed 

Diamond Aircraft Mandatory Service 

Bulletin DAI MSB 42–146 and DAI MSB 

42NG–087, dated November 15, 2022, 

(issued as one document). The service 

bulletin specifies the serial numbers for 

airplanes identified as Group 2 in the 

requirements of this proposed AD. 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 ADDRESSES. 

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 service 

information described 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 retain the 

requirement of AD 2022–21–15 to 

replace rudder T-yoke axle part number 

P/N LN 9037–M6x90 with rudder Tyoke axle P/N D60–5320–00–32. This 

proposed AD would require, for certain 

airplanes, inspecting the rudder steering 

bracket edge distance and depending on 

the inspection results, inspecting the Tyoke bolt hole for wear and play, and 

corrective actions if necessary. For 

certain airplanes, this proposed AD 

would also require applying torque seal 

marks on the T-yoke bolt head and selflocking nut. For all airplanes, this 

proposed AD would require repetitively 

inspecting the torque seal marks on the 

T-yoke bolt head for proper alignment, 

and the self-locking nut for proper 

installation, and corrective action if 

necessary. This proposed AD would 

also prohibit the installation of affected 

parts. 

Differences Between This Proposed AD 

and the MCAI 

The MCAI applies to DAI Model DA 

42 M airplanes and this proposed AD 

does not because those airplanes do not 

have an FAA type certificate. 

Paragraph (3) of the MCAI specifies to 

contact the manufacturer for repair 

instructions and paragraph (7) of the 

MCAI specifies to contact the 

manufacturer for corrective actions if 

any discrepancy is found, but for both 

of those corrective actions, this 

proposed AD would require contacting 

either the Manager, International 

Validation Branch, FAA; EASA; or 

Diamond’s EASA Design Organization 

Approval (DOA) instead. If approved by 

the DOA, the approval must include the 

DOA-authorized signature. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 205 

airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Inspection of rudder steering 

bracket edge distance.

0.25 work-hour × $85 per hour = 

$21.25.

lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 88, No. 215 / Wednesday, November 8, 2023 / Proposed Rules 77063 

Since the replacement or repair 

instructions could vary significantly 

from airplane to airplane if 

discrepancies are found during the 

inspections, the FAA has no data to 

determine the number of airplanes that 

would need follow-on actions or what 

the cost per airplane would be. 

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 that the 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

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by: 

■ a. Removing Airworthiness Directive 

2022–21–15, Amendment 39–22214 (87 

FR 67541, November 9, 2022); and 

■ b. Adding the following new 

airworthiness directive: 

Diamond Aircraft Industries GmbH: Docket
