SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2021–17, dated April 28, 2021 (also 

referred to 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 on the internet at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0085. 

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–700–1A10 and BD–700–1A11 

airplanes. The NPRM published in the 

Federal Register on February 3, 2022 

(87 FR 6082). The NPRM was prompted 

by reports of oxygen leaks caused by 

cracked, brittle, or broken oxygen hoses 

that were found during scheduled 

maintenance tests of the airplane 

oxygen system. The NPRM proposed to 

require an inspection of the oxygen hose 

assembly to determine if an affected part 

number is installed, and replacement of 

affected oxygen hoses. For certain 

airplanes, the NPRM proposed to allow 

repetitive testing of the oxygen system 

until affected hoses are replaced. The 

NPRM also proposed to prohibit 

installation of an affected oxygen hose. 

The FAA is issuing this AD to address 

a leak in the oxygen line, which may 

result in failure to provide oxygen to 

passengers and crew and result in an 

oxygen enriched atmosphere creating a 

fire risk on the airplane. See the MCAI 

for additional background information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The following presents 

the comments received on the NPRM 

and the FAA’s response to each 

comment. Air Line Pilots Association, 

International (ALPA), an individual 

commenter, and Bombardier indicated 

their support for the NPRM. 

Request To Revise the Conditions for 

the Aircraft Completion Center 

Supplemental Type Certificate (STC) 

Date 

Bombardier requested that the FAA 

revise the conditions for the Aircraft 

Completion Center STC date. 

Bombardier stated that the use of the 

date when the Aircraft Completion 

Center STC was issued as specified in 

paragraphs (h)(1)(i), (h)(1)(ii) and (h)(3) 

of the proposed AD, will, in some cases, 

be inconsistent with the instructions 

given in the service bulletin. 

Bombardier commented that in cases 

where multiple configurations are 

approved by the Aircraft Completion 

Center STC, the date that the STC was 

issued is not necessarily indicative of 

the age of the hoses and should not be 

used. Bombardier stated that, for 

example, STC ST03088NY, was issued 

April 20, 2012, but has been used since 

then to approve many serial-numberspecific configurations. 

Bombardier suggested that the date 

used to determine whether operators 

may perform interim inspections and 

delay hose replacement be based on one 

of the following conditions: 

• Initial approval of the aircraft 

completion modification was 

demonstrated by a serial number 

specific to the STC and the date the STC 

was issued; or 

• Initial approval of the aircraft 

completion modification was 

demonstrated on an STC that approves 

multiple configurations by the initial 

approval date of the serial number 

specific configuration that correlates to 

the date STC was added to the approved 

configuration list. 

Bombardier commented that the 

suggestion is consistent with the service 

information provided in Bombardier 

Advisory Wire AW700–35–0794, which 

includes an explanation of how to find 

the ‘‘Aircraft Completion STC date’’ 

(expression used in the associated 

service information), for cases where 

Bombardier is the STC holder. 

The FAA disagrees with the 

commenter’s implication that the ability 

to delay hose replacement is determined 

by the date of the STC. The date as 

given relative to an STC is only for the 

optional interim testing and if all 

conditions are met; whether an operator 

may delay replacement is determined 

solely based on serial numbers. If an 

STC is installed with the referenced 

hoses, the serial numbers can be 

checked on the hoses. The FAA has not 

changed this AD in this regard. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, 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.

This service information describes 

procedures for doing an inspection of 

the oxygen hose assembly installations 

to determine if a part number within the 

series O2C20T1 is installed, and 

replacing the oxygen hose if necessary. 

For certain airplanes, the service 

information specifies optional repetitive 

testing of the oxygen system that would 

allow for delay of the replacement. 

These documents are distinct since they 

apply to different airplane serial 

numbers. 

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 will 

affect 409 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 

Up to 36 work-hours × $85 per hour = Up to $3,060 $0 Up to $3,060 .................................. Up to $1,251,540. 

ESTIMATED COSTS FOR OPTIONAL ACTIONS

Labor cost Parts cost Cost per product 

Up to 25 work-hours × $85 per hour = Up to $2,125 ............. Up to $125 ............................................. Up to $2,250. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected operators. 

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.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA is adopting a new AD for 

certain serial-numbered Robinson 

Helicopter Company Model R22 BETA, 

R44, and R44 II helicopters. This AD 

was prompted by reports of intermittent 

or abnormal operation of the governor. 

In normal conditions, a properly 

functioning governor maintains engine 

speed within acceptable limits. 

Intermittent or abnormal operation of 

the governor may result in engine 

overspeed or underspeed conditions 

during flight. If the engine governor 

malfunctions, the pilot may assume 

manual throttle control by firmly 

gripping the throttle and overriding the 

governor’s friction clutch, or by 

switching the governor off. In the event 

of low rotor RPM, an alarm sounds. This 

condition, if not addressed, could result 

in reduced control of the helicopter and 

subsequent emergency landing or loss of 

control of the helicopter. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

FAA’s Determination 

The FAA is issuing this AD because 

the agency has determined the unsafe 

condition described previously is likely 

to exist or develop in other products of 

the same type designs. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Robinson R22- 

series Governor & Engine RPM Sensor 

Connector Upgrade Kit Instructions, KI– 

288 Revision A, and Robinson R44- 

series Governor & Engine RPM Sensor 

Connector Upgrade Kit Instructions, KI– 

287 Revision A, each dated February 23, 

2022. This service information specifies 

procedures to inspect the engine RPM 

sensor wiring for damage, repair that 

wiring, and modify the governor wiring 

connection to the airframe harness with 

different connectors for improved 

clearance and strain relief. 

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 ADDRESSES. 

Other Related Service Information 

The FAA reviewed Robinson 

Helicopter Company R22 Service 

Bulletin SB–119, and Robinson 

Helicopter Company R44 Service 

Bulletin SB–111, each dated February 

23, 2022. This service information 

specifies inspecting the sensor wiring, 

installing a governor wiring kit, and 

accomplishing the starting engine and 

run-up checklist to verify proper 

governor operation. 

AD Requirements 

This AD requires inspecting the 

engine RPM sensor wiring for damage, 

and depending on the outcome, 

accomplishing repairs. This AD also 

requires modifying the governor wiring 

connection to the airframe harness by 

installing wiring kit KI–288 for Model 

R22 BETA helicopters and wiring kit 

KI–287 for Model R44 and R44 II 

helicopters.
