Airworthiness Directives; Bombardier, 

Inc., Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Bombardier, Inc., Model CL– 

600–1A11 (600), CL–600–2A12 (601), 

and CL–600–2B16 (601–3A, 601–3R, 

and 604 Variants) airplanes. This 

proposed AD was prompted by a report 

that some rudder power control unit 

(PCU) load limiters were found in 

service with the crimping missing from 

the end cap; therefore, the pilot 

command from the load limiter might 

not transmit correctly. This proposed 

AD would require a one-time inspection 

of the rudder PCU load limiters for 

correct crimping of the end cap, and 

replacing any defective rudder PCU load 

limiter. For certain airplanes, this 

proposed AD would also require 

repetitive testing of the rudder PCU load 

limiter for correct functioning, and 

applicable corrective actions. The FAA 

is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by July 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–33, dated October 6, 2021 (also 

referred to after this as the MCAI), to 

correct an unsafe condition for certain 


lotter on DSK11XQN23PROD with PROPOSALS1
35126 Federal Register / Vol. 87, No. 111 / Thursday, June 9, 2022 / Proposed Rules 

Bombardier, Inc., Model CL–600–1A11 

(600), CL–600–2A12 (601), and CL–600– 

2B16 (601–3A, 601–3R, and 604 

Variants) airplanes. You may examine 

the MCAI in the AD docket at https:// 

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0603. 

This proposed AD was prompted by 

a report that some rudder PCU load 

limiters were found in service with the 

crimping missing from the end cap; 

therefore, the pilot command from the 

load limiter might not transmit 

correctly. The FAA is proposing this AD 

to address defective rudder PCU load 

limiters, which could result in incorrect 

transmission of the pilot command, and 

loss of control of the rudder. See the 

MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued the following 

service information. 

• Bombardier Service Bulletin 604– 

27–039, Revision 01, dated April 6, 

2021. 

• Bombardier Service Bulletin 600– 

0776, dated December 7, 2020. 

• Bombardier Service Bulletin 601– 

0648, dated December 7, 2020. 

This service information describes 

procedures for a one-time inspection of 

the rudder PCU load limiters for correct 

crimping of the end cap, and replacing 

any defective PCU load limiter. These 

documents are distinct because they 

apply to different airplane 

configurations. 

Bombardier has also released the 

following service information. 

• Bombardier Service Bulletin 605– 

27–003, dated December 7, 2020. 

• Bombardier Service Bulletin 650– 

27–010, dated December 7, 2020. 

This service information describes 

procedures for repetitive testing of 

certain PCU load limiters for proper 

functioning and applicable corrective 

actions (performing the one-time 

inspection of the rudder PCU load 

limiters for correct crimping of the end 

cap, and replacing any defective PCU 

load limiter). This service information 

also describes procedures for a one-time 

inspection of the rudder PCU load 

limiters for correct crimping of the end 

cap, and replacing any defective PCU 

load limiter, which terminates the 

repetitive tests. These documents are 

distinct because they apply to different 

airplane configurations. 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 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 the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI and service 

information referenced above. The FAA 

is proposing this AD because the FAA 

evaluated all the relevant information 

and determined 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 service information already 

described. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 379 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Up to 2 work-hours × $85 per hour = Up to $170 ........................................................... $0 Up to $170 .......... Up to $64,430. 

The FAA estimates the following 

costs to do any necessary on-condition 

replacement that would be required 

based on the results of any required 

inspection. The FAA has no way of 

determining the number of aircraft that 

might need this on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

10 work-hours × $85 per hour = $850 (per rudder PCU load limiter) .................................................................... $50 $900 

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,

Airworthiness Directives; De Havilland 

Aircraft of Canada Limited (Type 

Certificate Previously Held by 

Bombardier, Inc.) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2020–04–20, which applies to certain 

De Havilland Aircraft of Canada Limited 

Model DHC–8–400 series airplanes. AD 

2020–04–20 requires repetitive 

inspections of certain parts for 

discrepancies that meet specified 

criteria, and replacement as necessary; 

repetitive inspections of certain parts for 

damage and wear, and rework of parts; 

and electrical bonding checks of certain 

couplings. AD 2020–04–20 also requires 

revising the existing maintenance or 

inspection program, as applicable, to 

incorporate new or more restrictive 

airworthiness limitations. For certain 

airplanes, AD 2020–04–20 allows a 

modification that would terminate the 

repetitive inspections. Since the FAA 

issued AD 2020–04–20, the FAA has 

determined that a more robust lightning 

ignition protection design is necessary 

and that additional airplanes are 

affected by the unsafe condition. This 

proposed AD would continue to require 

the actions in AD 2020–04–20, revise 

the applicability by adding airplanes, 

and require, for certain airplanes, the 

previously optional rework and retrofit 

of certain parts of the fuel system. Doing 

the rework and retrofit would terminate 

the retained initial and repetitive 

inspections in this AD. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by July 25, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
