Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 

CF–2020–23, dated June 24, 2020 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain MHI RJ Aviation 

ULC Model CL–600–2C10 (Regional Jet 

Series 700, 701 & 702), CL–600–2C11 

(Regional Jet Series 550), and CL–600– 

2D24 (Regional Jet Series 900) airplanes. 

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–2020– 

1137. 

This proposed AD was prompted by 

a report that some piccolo ducts for the 

wing anti-ice system have bleed holes 

that do not conform to requirements 

(such as being undersized, un-burred, or 

in the wrong location). The FAA is 

proposing this AD to address nonconforming piccolo duct bleed holes, 

which could lead to degradation of the 

wing anti-ice protection of the leading 

edge of certain slats, and possibly result 

in airplane handling issues during 

critical phases of flight. See the MCAI 

for additional background information. 

Related Service Information Under 1 

CFR Part 51 

Bombardier has issued Service 

Bulletin 670BA–30–025, dated 

December 17, 2019. This service 

information describes, for certain 

airplanes, procedures for replacement of 

affected piccolo ducts with new piccolo 

ducts. This service information also 

describes, for certain other airplanes, 

procedures for inspection for the 

presence of affected wing anti-icing 

system piccolo ducts, and depending on 

inspection results, replacement of 

affected piccolo ducts with new piccolo 

ducts or contacting the manufacturer for 

further instruction. 

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 Requirements of This NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 21 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 16 work-hours × $85 per hour = Up to $1,360 .......................................... Up to $7,534 ......... Up to $8,894 ......... Up to $186,774. 

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) 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.

Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Airbus Helicopters Model AS332L, 

AS332L1, AS332C, and AS332C1 

helicopters. This proposed AD was 

prompted by the failure of a second 

stage planet gear installed in the main 

gearbox (MGB). This proposed AD 

would require identifying the part 

number of each second stage planet gear 

assembly installed in the MGB, 

replacing an MGB having certain second 

stage planet gear assembly part numbers 

with a serviceable MGB, modifying the 

helicopter by installing a full flow 

magnetic plug (FFMP), repetitively 

inspecting the FFMP and the MGB 

bottom housing and conical housing for 

metal particles, analyzing any metal 

particles that are found, and applying 

corrective actions if necessary, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference. 

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 February 4, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
