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 BD– 

700–1A10 and BD–700–1A11 airplanes. 

This proposed AD was prompted by 

reports of the loss of all air data system 

information provided to the flightcrew 

during flight; the air data system 

information was recovered as the 

airplane descended to lower altitudes. 

This proposed AD would require 

revising the existing airplane flight 

manual (AFM) to update the Unreliable 

Airspeed and Landing Distance Factor 

emergency procedures, which provide 

instructions for the flightcrew to 

stabilize the airspeed and altitude. 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 May 26, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

https://www.regulations.gov. Follow the 

instructions for submitting comments.

Background 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2020–50, dated November 20, 2020 

(TCCA AD CF–2020–50) (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–700–1A10 and BD–700– 

1A11 airplanes. You may examine the 

MCAI in the AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0453. 

This proposed AD was prompted by 

reports of the loss of all air data system 

information provided to the flightcrew 

during flight; the air data system 

information was recovered as the 

airplane descended to lower altitude. 

An investigation determined that the 

root cause was usually high altitude 

icing (ice crystal contamination). The 

FAA is proposing this AD to address 

loss of all air data system information, 

which could lead to loss of continued 

safe flight and landing of the airplane. 

See the MCAI for additional background 

information.

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 

revising the existing AFM to update the 

Unreliable Airspeed and Landing 

Distance Factor emergency procedures, 

which provide instructions for the 

flightcrew to stabilize the airspeed and 

altitude. 

TCCA AD CF–2020–50 requires 

operators to ‘‘inform all flight crews’’ of 

revisions to the AFM, and thereafter to 

‘‘operate the aeroplane accordingly.’’ 

However, this proposed AD would not 

specifically require those actions as 

those actions are already required by 

FAA regulations. FAA regulations 

require operators furnish to pilots any 

changes to the AFM (for example, 14 

CFR 121.137), and to ensure the pilots 

are familiar with the AFM (for example, 

14 CFR 91.505). As with any other 

flightcrew training requirement, training 

on the updated AFM content is tracked 

by the operators and recorded in each 


lotter on DSK11XQN23PROD with PROPOSALS1
Federal Register / Vol. 87, No. 69 / Monday, April 11, 2022 / Proposed Rules 21049 

pilot’s training record, which is 

available for the FAA to review. FAA 

regulations also require pilots to follow 

the procedures in the existing AFM 

including all updates. 14 CFR 91.9 

requires that any person operating a 

civil aircraft must comply with the 

operating limitations specified in the 

AFM. Therefore, including a 

requirement in this proposed AD to 

operate the airplane according to the 

revised AFM would be redundant and 

unnecessary. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 395 

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 

1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $33,575 

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, 

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 AS–365N2, 

AS 365 N3, EC 155B, EC155B1, and SA– 

365N1 helicopters. This proposed AD 

was prompted by a large amount of 

critical scale particles found on the tail 

rotor gearbox (TGB) chip detector 

magnetic plug during an unscheduled 

check of the TGB. The particles 

belonged to the double bearing (pitch 

control rod bearing) installed inside the 

TGB. This proposed AD would require 

repetitive inspections of the TGB chip 

detector for particles, analyzing any 

particles collected, performing a double 

bearing washing, repetitive 

replacements of certain part-numbered 


lotter on DSK11XQN23PROD with PROPOSALS1EP11AP22.021</GPH>
