ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

De Havilland Aircraft of Canada Limited 

Model DHC–8–401 and –402 airplanes. 

This AD was prompted by reports of 

nose wheel steering (NWS) hydraulic 

motors jamming during pushback or 

towing. This AD requires doing an 

inspection to determine the part number 

and serial number of the NWS hydraulic 

motor, and re-identifying or replacing 

the NWS hydraulic motor if necessary. 

This AD also prohibits the installation 

of certain NWS hydraulic motors. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective August 10, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 10, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–28, dated August 5, 2021 (also 

referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain De Havilland 

Aircraft of Canada Limited Model DHC– 

8–401 and –402 airplanes. You may 

examine the MCAI in the AD docket at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2022–0394. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain De Havilland Aircraft of 

Canada Limited Model DHC–8–401 and 

–402 airplanes. The NPRM published in 

the Federal Register on April 6, 2022 

(87 FR 19813). The NPRM was 

prompted by reports of NWS hydraulic 

motors jamming during pushback or 

towing. The NPRM proposed to require 

doing an inspection to determine the 

part number and serial number of the 

NWS hydraulic motor, and reidentifying or replacing the NWS 

hydraulic motor if necessary. The 

NPRM also proposed to prohibit the 

installation of certain NWS hydraulic 

motors. The FAA is issuing this AD to 

address a possible NWS hydraulic 

motor jam, which could lead to a 

runway excursion and loss of 

controllability of the airplane. See the 

MCAI for additional background 

information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

The Air Line Pilots Association, 

International (ALPA), who supported 

the NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products.

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,

14 CFR Part 97 

[Docket No. 31437; Amdt. No. 4016] 

Standard Instrument Approach 

Procedures, and Takeoff Minimums 

and Obstacle Departure Procedures; 

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This rule amends, suspends, 

or removes Standard Instrument 

Approach Procedures (SIAPs) and 

associated Takeoff Minimums and 

Obstacle Departure Procedures for 

operations at certain airports. These 

regulatory actions are needed because of 

the adoption of new or revised criteria, 

or because of changes occurring in the 

National Airspace System, such as the 

commissioning of new navigational 

facilities, adding new obstacles, or 

changing air traffic requirements. These 

changes are designed to provide for the 

safe and efficient use of the navigable 

airspace and to promote safe flight 

operations under instrument flight rules 

at the affected airports. 

DATES: This rule is effective July 6, 

2022. The compliance date for each 

SIAP, associated Takeoff Minimums, 

and ODP is specified in the amendatory 

provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of July 6, 2022. 

ADDRESSES: Availability of matter 

incorporated by reference in the 

amendment is as follows:

MacArthur Blvd., Registry Bldg 29 

Room 104, Oklahoma City, OK 73169. 

Telephone: (405) 954–4164. 

SUPPLEMENTARY INFORMATION: This rule 

amends 14 CFR part 97 by amending the 

referenced SIAPs. The complete 

regulatory description of each SIAP is 

listed on the appropriate FAA Form 

8260, as modified by the National Flight 

Data Center (NFDC)/Permanent Notice 

to Airmen (P–NOTAM), and is 

incorporated by reference under 5 

U.S.C. 552(a), 1 CFR part 51, and 14 

CFR 97.20. The large number of SIAPs, 

their complex nature, and the need for 

a special format make their verbatim 

publication in the Federal Register 

expensive and impractical. Further, 

airmen do not use the regulatory text of 

the SIAPs, but refer to their graphic 

depiction on charts printed by 

publishers of aeronautical materials. 

Thus, the advantages of incorporation 

by reference are realized and 

publication of the complete description 

of each SIAP contained on FAA form 

documents is unnecessary. This 

amendment provides the affected CFR 

sections, and specifies the SIAPs and 

Takeoff Minimums and ODPs with their 

applicable effective dates. This 

amendment also identifies the airport 

and its location, the procedure and the 

amendment number. 

Availability and Summary of Material 

Incorporated by Reference 

The material incorporated by 

reference is publicly available as listed 

in the ADDRESSES section. 

The material incorporated by 

reference describes SIAPs, Takeoff 

Minimums and ODPs as identified in 

the amendatory language for Part 97 of 

this final rule. 

The Rule 

This amendment to 14 CFR part 97 is 

effective upon publication of each 

separate SIAP and Takeoff Minimums 

and ODP as amended in the transmittal. 

For safety and timeliness of change 

considerations, this amendment 

incorporates only specific changes 

contained for each SIAP and Takeoff 

Minimums and ODP as modified by 

FDC permanent NOTAMs. 

The SIAPs and Takeoff Minimums 

and ODPs, as modified by FDC 

permanent NOTAM, and contained in 

this amendment are based on criteria 

contained in the U.S. Standard for 

Terminal Instrument Procedures 

(TERPS). In developing these changes to 

SIAPs and Takeoff Minimums and 

ODPs, the TERPS criteria were applied 

only to specific conditions existing at 

the affected airports. All SIAP 

amendments in this rule have been 

previously issued by the FAA in a FDC 

NOTAM as an emergency action of 

immediate flight safety relating directly 

to published aeronautical charts.
