AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2024–04– 

11, which applied to certain Airbus 

Canada Limited Partnership Model BD– 

500–1A10 and BD–500–1A11 airplanes. 

AD 2024–04–11 required modifying the 

variable frequency generator (VFG) 

power-feeder harness routing. Since the 

FAA issued AD 2024–04–11, the FAA 

received a report of damage to a VFG 

power-feeder harness, resulting in the 

loss of the associated VFG and the 

posting of the L GEN FAIL (Caution) 

message. This AD continues to require 

modifying the VFG power-feeder 

harness routing, and also requires 

inspecting the VFG power-feeder 

harnesses for damage and clearance, 

repairing or replacing the VFG powerfeeder harnesses if necessary, modifying 

and adjusting the VFG power-feeder 

harnesses if necessary, and prohibiting 

dispatch of certain airplanes under 

certain master minimum equipment list 

(MMEL) items; as specified in a 

Transport Canada emergency AD, which 

is incorporated by reference. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective November 

14, 2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD

Background 

The FAA issued AD 2024–04–11, 

Amendment 39–22690 (89 FR 21179, 

March 27, 2024) (AD 2024–04–11), for 

certain Airbus Canada Limited 

Partnership Model BD–500–1A10 and 

BD–500–1A11 airplanes. AD 2024–04– 

11 was prompted by an MCAI originated 


ddrumheller on DSK120RN23PROD with RULES1
86232 Federal Register / Vol. 89, No. 210 / Wednesday, October 30, 2024 / Rules and Regulations 

by Transport Canada, which is the 

aviation authority for Canada. Transport 

Canada issued AD CF–2023–24, dated 

April 6, 2023 (Transport Canada AD 

CF–2023–24), to correct an unsafe 

condition. 

AD 2024–04–11 required modifying 

the VFG power-feeder harness routing. 

The FAA issued AD 2024–04–11 to 

prevent damage to VFG power-feeder 

harnesses from chafing due to vibration. 

The unsafe condition, if not addressed, 

could lead to a loss of generated power 

from both VFGs, or to a fire in the case 

of flammable fluid contact with arcing 

wires. 

Actions Since AD 2024–04–11 Was 

Issued 

Since the FAA issued AD 2024–04– 

11, Transport Canada superseded 

Transport Canada AD CF–2023–24 and 

issued Transport Canada Emergency AD 

CF–2024–34, dated September 19, 2024 

(Transport Canada Emergency AD CF– 

2024–34) to correct an unsafe condition 

for certain Airbus Canada Limited 

Partnership (ACLP) Model BD–500– 

1A10 and BD–500–1A11 airplanes. The 

MCAI states damage to a VFG harness 

has been reported, which resulted in the 

loss of the associated VFG and the 

posting of the L GEN FAIL (Caution) 

message. An investigation determined 

that the in-service event occurred after 

the incorporation of Part C of ACLP 

Service Bulletin BD500–534101, Issue 

007, dated October 2, 2020, which 

introduced a new bracket on both sides 

of the airplane to move the VFG powerfeeder harness away from the wheel 

bins to prevent chafing. Transport 

Canada required the actions in that 

service bulletin in Transport Canada AD 

CF–2023–24 (which corresponds with 

FAA AD 2024–04–11) to mitigate the 

risks associated with VFG power-feeder 

harness/wheel bin chafing. It has been 

discovered that implementation of Part 

C of ACLP SB BD500–534101 (Issues 

005 through 008) could potentially 

cause an unsupported VFG powerfeeder harness length in a different 

location on both sides of the airplane. In 

addition, dispatching the airplane with 

certain items inoperative under the 

MMEL might exacerbate this risk. 

Transport Canada Emergency AD CF– 

2024–34 prohibits dispatch of airplanes 

under certain MMEL items to mitigate 

the exacerbated risk due to dispatching 

airplanes with certain items inoperative. 

Transport Canada subsequently 

superseded Transport Canada 

Emergency AD CF–2023–34 and issued 

Transport Canada Emergency AD CF– 

2024–34R1, dated October 15, 2024 

(Transport Canada Emergency AD CF– 

2024–34R1) to clarify the requirements 

of Part II of Transport Canada 

Emergency AD CF–2024–34. Transport 

Canada Emergency AD CF–2024–34R1 

does not change the requirements or 

applicability of Transport Canada 

Emergency AD CF–2024–34. 

The FAA is issuing this AD to address 

damage to VFG power-feeder harnesses 

caused by unsupported VFG powerfeeder harness length. The unsafe 

condition, if not addressed, could lead 

to a loss of generated power from both 

VFGs and loss of critical aircraft systems 

if alternate generators are also lost. You 

may examine the MCAI in the AD 

docket at regulations.gov under Docket 

No. FAA–2024–2415. 

Explanation of Retained Requirements 

Although this AD does not explicitly 

restate the requirements of AD 2024– 

04–11, this AD retains all of the 

requirements of AD 2024–04–11. Those 

requirements are referenced in 

Transport Canada Emergency AD CF– 

2024–34 and AD CF–2024–34R1, which, 

in turn, are referenced in paragraph (g) 

of this AD. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

Transport Canada Emergency AD CF– 

2024–34 and AD CF–2024–34R1 specify 

procedures for modifying the VFG 

power-feeder harness routing, including 

a general visual inspection (GVI) for 

damage at the intersection of the VFG 

power-feeder harnesses and the surface 

of the wheel bins, and corrective actions 

including obtaining and following 

repair instructions; performing a GVI of 

the VFG power-feeder harnesses for 

damage (including chafing and kinks) 

and clearance between the VFG powerfeeder harnesses and main landing gear 

in the retracted position; repairing or 

replacing the VFG power-feeder 

harnesses (includes repairing wiring or 

the sleeve); modifying and adjusting the 

VFG power-feeder harnesses; and 

prohibiting dispatch of certain airplanes 

under certain MMEL items. These 

documents are distinct because 

Transport Canada Emergency AD CF– 

2024–34R1 clarifies the requirements of 

Transport Canada Emergency AD CF– 

2024–34. 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 

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 

is issuing this AD after determining that 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in Transport Canada 

Emergency AD CF–2024–34 and AD 

CF–2024–34R1 described previously, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. 

Clarification of Airplane Group 

Definition 

Transport Canada defines Group B 

airplanes as Model BD–500–1A10 

airplanes, having serial numbers 50001 

through 50047, and Model BD–500– 

1A11 airplanes, having serial numbers 

55001 through 55070. This AD clarifies 

Group B airplanes as only those 

airplanes on which Part C of the 

Accomplishment Instructions of ACLP 

SB BD500–534101, Issue 005, dated 

June 12, 2020, Issue 006, dated August 

14, 2020, Issue 007, dated October 2, 

2020, or Issue 008, dated March 13, 

2024, has not been done. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, AD 2024–04–11 is 

retained and Transport Canada 

Emergency AD CF–2024–34 and AD 

CF–2024–34R1 are incorporated by 

reference in this AD. This AD requires 

compliance with Transport Canada 

Emergency AD CF–2024–34 or AD CF– 

2024–34R1 in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Material 

required by Transport Canada 

Emergency AD CF–2024–34 and AD 

CF–2024–34R1 for compliance will be 

available at regulations.gov under 

Docket No. FAA–2024–2415 after this 

AD is published. 

FAA’s Justification and Determination 

of the Effective Date 

Section 553(b) of the Administrative 

Procedure Act (APA) (5 U.S.C. 551 et 

seq.) authorizes agencies to dispense 

with notice and comment procedures 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 210 / Wednesday, October 30, 2024 / Rules and Regulations 86233 

for rules when the agency, for ‘‘good 

cause,’’ finds that those procedures are 

‘‘impracticable, unnecessary, or contrary 

to the public interest.’’ Under this 

section, an agency, upon finding good 

cause, may issue a final rule without 

providing notice and seeking comment 

prior to issuance. Further, section 

553(d) of the APA authorizes agencies to 

make rules effective in less than thirty 

days, upon a finding of good cause. 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies forgoing notice 

and comment prior to adoption of this 

rule because Transport Canada issued 

an emergency AD indicating that 

damage to a VFG harness resulted in the 

loss of the associated VFG and the 

posting of the L GEN FAIL (Caution) 

message. Implementation of Part C of 

ACLP SB BD500–534101 (Issues 005 

through 008) could potentially cause an 

unsupported VFG power-feeder harness 

length in a different location on both 

sides of the airplane, which could lead 

to VFG power-feeder harness damage in 

these locations, which could lead to a 

loss of generated power from both VFGs 

and loss of critical aircraft systems if 

alternate generators are also lost. 

Additionally, the compliance time in 

this AD is shorter than the time 

necessary for the public to comment and 

for publication of the final rule. 

Accordingly, notice and opportunity for 

prior public comment are impracticable 

and contrary to the public interest 

pursuant to 5 U.S.C. 553(b). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forgo 

notice and comment. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 17 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Retained actions from AD 2024–04–11 ... Up to 51 work-hours × $85 per hour = 

$4,335.

Up to $3,538 .... Up to $7,873 ..... Up to $133,841. 

New GVI ................................................... 1 work-hour × $85 per hour = $85 ........... $0 ..................... $85 ................... $1,445. 

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 aircraft that might need these 

on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

Up to 60 work-hours × $85 per hour = Up to $5,100 per side .................... $9,940 per harness ............... Up to $15,040 per side. 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

(d) Subject 

Air Transport Association (ATA) of 

America Code 24, Electrical Power. 

(e) Unsafe Condition 

This AD was prompted by a report of 

damage to a variable frequency generator 

(VFG) power-feeder harness, resulting in the 

loss of the associated VFG and the posting of 

the L GEN FAIL (Caution) message. An 

investigation determined that the damage 

occurred after incorporation of Part C of 

Airbus Canada Limited Partnership (ACLP) 

Service Bulletin (SB) BD500–534101 (ACLP 

SB BD500–534101) at Issue 005 through 008, 

which introduced a new bracket to move the 

VFG power-feeder harness. The FAA is 

issuing this AD to address damage to VFG 

power-feeder harnesses caused by 

unsupported VFG power-feeder harness 

length. The unsafe condition, if not 

addressed, could lead to a loss of generated 

power from both VFGs and loss of critical 

aircraft systems if alternate generators are 

also lost. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 97 

[Docket No. 31572; Amdt. No. 4136] 

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 October 30, 

2024. 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 October 30, 

2024. 

ADDRESSES: Availability of matter 

incorporated by reference in the 

amendment is as follows:

Room 217, Oklahoma City, OK 73099. 

Telephone: (405) 954–1139. 

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 Air Missions (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, 

pilots 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. 

The circumstances that created the 

need for these SIAP and Takeoff 

Minimums and ODP amendments 

require making them effective in less 

than 30 days. 

Because of the close and immediate 

relationship between these SIAPs, 

Takeoff Minimums and ODPs, and 

safety in air commerce, I find that notice 

and public procedure under 5 U.S.C. 

553(b) are impracticable and contrary to
