ACTION: Final rule. 

SUMMARY: The FAA is adopting 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

SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–13, dated April 1, 2021 (TCCA AD 

CF–2021–13) (also referred to as the 

MCAI), to correct an unsafe condition 

for Bombardier, Inc., Model CL–600– 

1A11 (600), CL–600–2A12 (601), and 

CL–600–2B16 (601–3A, 601–3R, and 

604 Variants) airplanes, equipped with 

any Cox & Co. 3043 or 3044 series 

(potable water-line) ribbon heater. You 

may examine the MCAI in the AD 

docket on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0090. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Bombardier, Inc., Model 

CL–600–1A11 (600), CL–600–2A12 

(601), and CL–600–2B16 (601–3A, 601– 

3R, and 604 Variants) airplanes. The 

NPRM published in the Federal 

Register on February 8, 2022 (87 FR 

7056). The NPRM was prompted by a 

report of smoke in the aft cabin during 

a maintenance activity, which an 

investigation determined was caused by 

a faulty drain line ribbon heater. The 

NPRM proposed to require a general 

visual inspection of all affected potable 

water-line ribbon heater installations 

and corrective actions and other 

specified actions. The FAA is issuing 

this AD to address faulty potable waterline ribbon heaters, which, if not 

corrected, could lead to an onboard fire. 

See the MCAI for additional background 

information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. The FAA has 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued Service 

Bulletin 601–0644, Revision 1, dated 

January 29, 2019; and Service Bulletin 

604–30–007, Revision 1, dated January 

29, 2019. This service information 

describes procedures for a general visual 

inspection of all affected potable waterline ribbon heater installations for any 

discrepancy and applicable corrective 

actions and other specified actions. 

Discrepancies include discoloration, 

blistering or cracking of insulation, 

signs of wear, or heat damage. 

Corrective actions include replacement 

of discrepant insulation and ribbon 

heaters. Other specified actions include 

identifying the potable water-line ribbon 

heater pigtail wire configuration, 

installing a fuse to the ribbon heater 

power lead, and testing the potable 

water-line heater system of each ribbon 

heater. These documents are distinct 

since they apply to different airplane 

models. 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 585 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 80 / Tuesday, April 26, 2022 / Rules and Regulations 24411 

ESTIMATED COSTS FOR REQUIRED ACTIONS

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

Up to 30 work-hours × $85 per hour = Up to $2,550 $268 Up to $2,818 .................................. Up to $1,648,530. 

The FAA estimates the following 

costs to do any necessary on-condition 

action 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 this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

Up to 30 work-hours × $85 per hour = $2,550 ............................................................ Up to $39,552 * ......................................... $42,102 

* The parts cost for a single potable water-line ribbon heater and associated material is $4,944. The estimated cost above assumes the worst 

case scenario of replacing all eight ribbon heaters on an airplane configured with eight ribbon heaters. 

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.
