91248 Federal Register / Vol. 89, No. 223 / Tuesday, November 19, 2024 / Rules and Regulations 

Exemptions from these particular 

subsections are justified on a case-by-case 

basis to be determined at the time a request 

is made for the following reasons: 

(a) From subsection (c)(3) (Accounting for 

Disclosures) because the release of the 

accounting of disclosures could alert the 

subject of an investigation of an actual or 

potential criminal, civil, or regulatory 

violation to the existence of the investigation 

and reveal investigative interest on the part 

of DHS as well as the recipient agency. 

Disclosure of the accounting would, 

therefore, present a serious impediment to 

law enforcement efforts and/or efforts to 

preserve national security. Disclosure of the 

accounting would also permit the individual 

who is the subject of a record to impede the 

investigation, tamper with witnesses or 

evidence, and avoid detection or 

apprehension, which would undermine the 

entire investigative process. 

(b) From subsection (d) (Access and 

Amendment to Records) because access to 

the records contained in this system of 

records could apprise the subject of an 

investigation of an actual or potential 

criminal, civil, or regulatory violation to the 

existence of the investigation and reveal 

investigative interest on the part of DHS or 

another agency. Access to the records could 

permit the individual who is the subject of 

a record to impede the investigation, tamper 

with witnesses or evidence, and avoid 

detection or apprehension. Amendment of 

the records could interfere with ongoing 

investigations and law enforcement activities 

and impose an unreasonable administrative 

burden by requiring investigations to be 

continually reinvestigated. In addition, 

permitting access and amendment to such 

information could disclose security-sensitive 

information that could be detrimental to 

homeland security. 

(c) From subsection (e)(1) (Relevancy and 

Necessity of Information) because in the 

course of investigations into potential 

violations of federal law, the accuracy of 

information obtained or introduced 

occasionally may be unclear, or the 

information may not be strictly relevant or 

necessary to a specific investigation. In the 

interests of effective law enforcement, it is 

appropriate to retain all information that may 

aid in establishing patterns of unlawful 

activity. 

(d) From subsections (e)(4)(G), (e)(4)(H), 

and (e)(4)(I) (Agency Requirements) and (f) 

(Agency Rules), because portions of this 

system are exempt from the individual access 

provisions of subsection (d) for the reasons 

noted above, and DHS is therefore not 

required to establish requirements, rules, or 

procedures with respect to such access. 

Providing notice to individuals concerning 

the existence of records about them in the 

system of records or otherwise setting up 

procedures pursuant to which individuals 

may access and view records pertaining to 

themselves in the system would undermine 

investigative efforts and reveal the identities 

of witnesses, potential witnesses, and 

confidential informants.

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 MDHI Model 369, 369A, 369D, 

369E, 369F, 369FF, 369H, 369HE, 

369HM, 369HS, 500N, and 600N 

helicopters with a torque tube part 

number 369H7133–7 installed. The 

NPRM published in the Federal 

Register on August 8, 2024 (89 FR 

64834). The NPRM was prompted by a 

report of a seized and damaged roller 

bearing assembly in the torque tube 

assembly of an MDHI Model MD369E 

helicopter. Since MDHI Model 369, 

369A, 369D, 369F, 369FF, 369H, 369HE, 

369HM, 369HS, 500N, and 600N 

helicopters have the same torque tube 

assembly installed, they are also 

affected by this unsafe condition. In the 

NPRM, the FAA proposed to require 

repetitively visually inspecting the 

torque tube for corrosion and cracks, 

repetitively visually inspecting the 

roller bearings for corrosion and 

degradation, performing a repetitive 

freedom-of-movement inspection of the 

torque tube assembly for binding or 

ratcheting, and corrective or additional 

action as necessary. The FAA is issuing 

this AD to address the unsafe condition 

on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

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. Except for minor editorial 

changes and clarifying two paragraph 

cross-references in the Required Actions 

section of this AD, paragraphs 

(g)(2)(iii)(A) and (g)(2)(iv), by replacing 

the text ‘‘paragraph (g)(2)(iii) of this 

AD’’ with ‘‘the introductory text of 

paragraph (g)(2)(iii) of this AD,’’ this AD 

is adopted as proposed in the NPRM. 

Costs of Compliance 

The FAA estimates that this AD 

affects 353 helicopters of U.S. registry. 

Labor costs are estimated at $85 per 

work-hour. Based on these numbers, the 

FAA estimates the following costs to 

comply with this AD. 

Visually inspecting the torque tube 

and roller bearings will take 1 workhour for an estimated cost of $85 per 

helicopter and $30,005 for the U.S. fleet, 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 223 / Tuesday, November 19, 2024 / Rules and Regulations 91249 

per inspection cycle. Inspecting the 

torque tube assembly for freedom of 

movement will take 0.75 work-hour for 

an estimated cost of $64 per helicopter 

and $22,595 for U.S. fleet cost, per 

inspection cycle. If required, a more indepth inspection of the roller bearings 

will take 0.25 work-hour for an 

estimated cost of $21 per helicopter, per 

instance. 

If required, replacing a torque tube 

will take 6 work-hours and parts will 

cost $4,773 for an estimated cost of 

$5,283 per torque tube replacement. 

Replacing a roller bearing will take 6 

work-hours and parts will cost $210 for 

an estimated cost of $720 per roller 

bearing replacement. 

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 that 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. 

List of Subjects in 14 CFR Part 39
