SUPPLEMENTARY INFORMATION: 

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2020–52, dated November 30, 2020 (also 

referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain Bombardier, Inc., 

Model BD–100–1A10 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–2021– 

0658. 

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 

BD–100–1A10 airplanes. The NPRM 

published in the Federal Register on 

August 12, 2021 (86 FR 44314). The 

NPRM was prompted by a discovery 

that a lockwire may not have been 

installed on the side stay actuator pin 

nut of the MLG. The NPRM proposed to 

require inspecting the left-hand and 

right-hand MLG side stay actuator 

assembly pin nut for the presence of a 

lockwire, and installing a lockwire if 

necessary. The FAA is issuing this AD 

to address a possible missing lockwire, 

which could result in loss of the nut, 

and if undetected, lead to the collapse 

of the affected MLG. 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.

Costs of Compliance 

The FAA estimates that this AD 

affects 623 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $52,955 

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 

1 work-hour × $85 per 

hour = $85 .................. $1 $86 

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.

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.

§ Section 

U.S.C. United States Code 

II. Background Information and 

Regulatory History 

On October 19, 2020, the Coast Guard 

published a notice of proposed 

rulemaking (NPRM) titled ‘‘Regulated 

Navigation Area; NW Natural PGM Site, 

Willamette River, Portland, OR’’ (85 FR 

66292). There we stated why we issued 

the NPRM, and invited comments on 

our proposed regulatory action related 

to this regulated navigation area (RNA). 

During the comment period that ended 

November 18, 2020, we received 1 

comment. 

III. Legal Authority and Need for Rule 

The Coast Guard is issuing this rule 

under authority in 46 U.S.C. 70034 

(previously 33 U.S.C. 1231). The Coast 

Guard is establishing a RNA to protect 

the engineered sediment cap located at 

the NW Natural PGM Site on the 

Willamette River in Portland, OR. This 

sediment cap is part of an Oregon 

Department of Environmental Quality 

(DEQ) required remedial action. The 

engineered sediment cap is designed to 

be compatible with normal vessel 

operations, but could be damaged by 

other maritime activities including 

anchoring, dragging, dredging, 

grounding of vessels, deployment of 

barge spuds, etc. Such damage could 

disrupt the function or impact the 

effectiveness of the cap to contain the 

underlying contaminated sediment and 

soil in these areas. 

The purpose of this rulemaking is to 

prevent disruption of the sediment cap 

which may result in hazardous 

conditions and harm to the marine 

environment. As such, this RNA is 

necessary to help ensure the sediment 

cap is protected and will do so by 

prohibiting maritime activities that 

could disturb or damage it. 

IV. Discussion of Comments, Changes, 

and the Rule 

As noted above, we received 1 

comment on our NPRM published 

October 19, 2020. The commenter 

expressed support in establishing this 

RNA to protect the cap on sediment in 

the Willamette River, noting that if the 

sediment were to increase in the 

Willimette River there is potential for 

flooding and other negative effects on 

users of the waterway. Accordingly, 

there are no changes in the regulatory 

text of this rule from the proposed rule 

in the NPRM. 

This rule establishes a RNA adjacent 

to the NW Natural PGM Site on the 

Willamette River in Portland, OR 

encompassing all waters above the 

sediment cap. The RNA prohibits 

activities which could disrupt or 

damage the sendiment cap on the river 

bed such as anchoring, dragging, 

dredging, trawling, or other related 

activities. The rule also specifies that 

operators who wish to engage in 

dredging, spudding, and vessel 

anchoring within the RNA must consult 

with Oregon DEQ and obtain prior
