SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 86, No. 110 / Thursday, June 10, 2021 / Rules and Regulations 30769 

part 39 by adding an AD that would 

apply to Bell Model 429 helicopters 

with a Bell EFS kit part number (P/N) 

429–706–069–101/–103/–105/–121/– 

123/–125/–139/–141/–143/or –157 

manufactured before July 2019, with a 

float supply hose manufactured before 

January 2014, installed, except for float 

supply hoses marked with ‘‘SB 025–69– 

21’’ above the external identification 

marking. The NPRM published in the 

Federal Register on March 23, 2021 (86 

FR 15434). In the NPRM, the FAA 

proposed to require within 100 hours 

time-in-service (TIS), removing each 

EFS supply hose and inspecting each 

end (also referred to as fitting or banjo) 

of the EFS supply hose using a certain 

plastic cable tie, and depending on the 

results of those inspections, removing 

from service certain parts and replacing 

those parts with airworthy parts. The 

NPRM also proposed to require marking 

a green dot on the base of certain supply 

hoses and writing ‘‘SB 025–69–21’’ 

above the external identification 

marking of the EFS with indelible ink. 

Finally, the NPRM proposed to prohibit 

installing any EFS supply hose 

manufactured before January 2014 

unless it has been inspected in 

accordance with the NPRM. The NPRM 

was prompted by Canadian AD CF– 

2020–21R1, issued August 19, 2020 

(Transport Canada AD CF–2020–21R1), 

by Transport Canada, which is the 

aviation authority for Canada, to correct 

an unsafe condition for all serialnumbered Bell Model 429 helicopters. 

Transport Canada advises that during 

maintenance on an EFS, the third 

compartment of the left forward float 

did not inflate. Transport Canada also 

advises that an investigation determined 

the supply hose for the gas flow from 

the pressurized cylinder to the float 

compartment was blocked due to a 

manufacturing defect. Bell advised that 

similar supply hoses are installed on 

various EFS part numbers, which could 

be installed on different helicopter type 

designs. Transport Canada further 

advises that this condition, if not 

detected and corrected, could result in 

partial inflation of the EFS during an 

emergency landing on water, preventing 

a timely egress from the helicopter, and 

injury to helicopter occupants. 

Accordingly, Transport Canada AD 

CF–2020–21R1 requires a one-time 

special detailed inspection of the 

affected system to verify that there is no 

blockage through the EFS supply hoses 

and replacement, as required, of the 

affected supply hoses. Transport Canada 

AD CF–2020–21R1 also renders any 

affected EFS supply hoses not eligible as 

a replacement part on Bell Model 429 

helicopters. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These helicopters have been approved 

by the aviation authority of Canada and 

are approved for operation in the United 

States. Pursuant to the FAA’s bilateral 

agreement with Canada, Transport 

Canada, its technical representative, has 

notified the FAA of the unsafe condition 

described in its AD. The FAA reviewed 

the relevant data and determined that 

air safety requires adopting this AD as 

proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on these helicopters. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Safran 

Aerosystems Services Service Bulletin 

No. 025–69–21, Revision 00, dated 

March 23, 2020 (SB 025–69–21). SB 

025–69–21 is attached to Bell Alert 

Service Bulletin No. 429–20–52, dated 

March 30, 2020 (ASB 429–20–52). SB 

025–69–21 is incorporated by reference 

in this AD. ASB 429–20–52 is not 

incorporated by reference in this AD. SB 

025–69–21 specifies, for certain EFSs 

manufactured before July 2019, and any 

float supply hose manufactured before 

January 2014, performing a special 

inspection to verify that there is no 

blockage through the float supply hoses 

of the EFS inflation system. 

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. 

Differences Between This AD and the 

Transport Canada AD 

The Transport Canada AD requires 

compliance within 600 hours air time or 

within the next 24-month inspection of 

the EFS, whichever occurs first, whereas 

this AD requires compliance within 100 

hours TIS. The Transport Canada AD 

limits the applicability to certain EFS 

supply hoses listed in SB 025–69–21, 

whereas this AD applies to certain EFS 

supply hoses manufactured before 

January 2014 but excludes EFS supply 

hoses marked with ‘‘SB 025–69–21.’’ 

Costs of Compliance 

The FAA estimates that this AD 

affects 110 helicopters of U.S. Registry 

and that operators may incur the 

following costs in order to comply with 

this AD. Labor costs are estimated at $85 

per work-hour. 

Removing and inspecting each EFS 

supply hose will take about 0.75 workhour, for an estimated cost of $64 per 

hose. 

Installing or replacing each EFS 

supply hose will take about 0.10 workhour with a minimal parts cost, for an 

estimated cost of $9 per hose. 

Marking each EFS supply hose with a 

green dot and the applicable service 

bulletin number will take a minimal 

amount of time at a nominal cost. 

According to Safran’s service 

information, some of the costs of this 

AD may be covered under warranty, 

thereby reducing the cost impact on 

affected individuals. The FAA does not 

control warranty coverage by Safran; 

accordingly, all costs are included in 

this cost estimate. 

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 helicopters 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
