SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to Bell Model 429 helicopters, 

serial numbers 57001 and subsequent. 

The NPRM published in the Federal 

Register on April 8, 2021 (86 FR 18218). 

In the NPRM, the FAA proposed to 

require establishing a life limit for 

certain part-numbered tail rotor 

outboard flapping bearings and a certain 

part-numbered hoist kit cable cutter 

cartridge. The NPRM also proposed to 

require establishing recurring CMR tasks 

for a certain part-numbered wheeled 

landing gear system, float/life raft kit, 

and hoist kit, and depending on the 

results of the CMR tasks, corrective 

action. The NPRM was prompted by 

Canadian AD CF–2017–16, dated May 

17, 2017, issued by Transport Canada, 

which is the aviation authority of 

Canada, to correct an unsafe condition 

for Bell Model 429 helicopters, serial 

numbers 57001 and subsequent. 

Transport Canada advises that Bell has 

established life limits and CMR tasks for 

various parts and accordingly revised 

Chapter 4—Airworthiness Limitations 

Schedule of Bell Helicopter 429 

Maintenance Manual BHT–429–MM–1 

to Revision 26, dated September 9, 2016 

(BHT–429–MM–1). Transport Canada 

states that failure to replace life-limited 

parts or perform CMR tasks as specified 

could result in an unsafe condition. 

Accordingly, the Transport Canada 

AD requires updating the maintenance 

schedule for the parts affected with the 

airworthiness life limits and CMR tasks 

in Revision 26 of BHT–429–MM–1. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

one commenter. The commenter was 

Bell. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Request To Change the Compliance 

Time of the Hoist Cable Anti-Foul 

Assembly Operational Check 

Bell requested changing the 

compliance time of the hoist cable antifoul assembly operational check from 

before the first flight of the day 

involving a hoist operation to after the 

last flight of the day. Bell requested this 

change to avoid the potential to suspend 

critical operations in order to 

accomplish the check and any required 

corrective maintenance because 

according to Bell, hoist equipment 

serves an essential service and may be 

required for critical missions with 

minimal notice. Bell further stated that 

this task was established based on the 

system safety assessment for the Bell 

Model 429 helicopter hoist installation 

and exposure based on a daily check 

after the last flight was considered in 

that assessment to conservatively meet 

acceptable reliability targets for its 

Major hazard classification. 

The FAA disagrees with the request to 

change the compliance time to after the 

last flight of the day. The compliance 

time of before the first flight of the day 

is standard practice in rotorcraft AD 

actions for enforceability purposes. 

However, this wording does not imply 

that the operational check and 

corrective action must be done on the 

same calendar day as the first flight of 

the day involving a hoist operation. In 

light of this, the FAA has made no 

changes based on this request. 

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 has notified the FAA about the 

unsafe condition described in its AD. 

The FAA reviewed the relevant data, 

considered the comments received, 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. Except, since issuance of 

the NPRM, Bell has updated its contact 

information to obtain service 

documentation by changing its website 

address and adding an email address. 

This final rule reflects those changes 

and this AD is otherwise adopted as 

proposed in the NPRM. None of the 

changes increase the economic burden 

on any operator. 

Related Service Information 

The FAA reviewed Chapter 4— 

Airworthiness Limitations Schedule of 

BHT–429–MM–1. This service 

information specifies airworthiness life 

limits, inspection intervals, and CMR 

requirements for parts installed on 

Model 429 helicopters. Revision 26 of 

this service information establishes life 

limits for a certain part-numbered tail 

rotor flapping outboard bearing and 

hoist kit cartridge cable cutter and CMR 

requirements for a certain partnumbered wheeled landing gear system, 

float/life raft kit, and hoist kit. 

Additionally, the FAA reviewed 

Chapter 96–47—600-Pound External 

Hoist Electrical System—Operational 

Check, of Bell 429 Maintenance Manual 

Supplement For 600-Pound External 

Hoist Kit, BHT–429–MMS–4, Revision 

1, dated March 14, 2014. This service 

information specifies inspection 

procedures and corrective action for 

various components of the hoist system. 

Lastly, the FAA reviewed Testing and 

Fault Isolation, pages 101–117/118, 

Cleaning, pages 401–405/406, and 

Scheduled Maintenance, pages 609– 

611/612, of Goodrich Rescue Hoist 

System Component Maintenance 

Manual 25–00–38–1, dated July 15, 

2009, for rescue hoist assembly part 

number 44316–12–102. This service 

information specifies maintenance 

procedures and lists replacement parts 

for this part-numbered Goodrich rescue 

hoist assembly. 

Differences Between This AD and the 

Transport Canada AD 

This AD requires corrective action for 

failed CMR tasks, whereas the Transport 

Canada AD does not. The Transport 

Canada AD requires accomplishing an 

operational check of the hoist cable antifoul assembly daily after the last flight, 

whereas this AD requires this action 

before the first flight of the day 

involving a hoist operation instead. 

Costs of Compliance 

The FAA estimates that this AD 

affects 110 helicopters of U.S. Registry. 

Labor rates are estimated at $85 per 

work-hour. Based on these numbers, the 

FAA estimates the following costs to 

comply with this AD. 

Replacing a tail rotor outboard 

flapping bearing takes about 4 workhours and parts cost about $7,500 for an 

estimated cost of $7,840 per helicopter 

and $862,400 for the U.S. fleet, per 

replacement cycle. Replacing a hoist kit 

cable cutter cartridge takes about 3 

work-hours and parts cost about $5,200 

for an estimated cost of $5,455 per 

helicopter and $600,050 for the U.S. 

fleet, per replacement cycle. 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Rules and Regulations 33093 

Performing a functional check of the 

wheeled landing gear system takes 

about 4 work-hours for an estimated 

cost of $340 per helicopter and $37,400 

for the U.S. fleet, per cycle. Performing 

a functional check of the float/life raft 

kit takes about 2 work-hours for an 

estimated cost of $170 per helicopter 

and $18,700 for the U.S. fleet, per cycle. 

Performing an operational check of 

the hoist kit cable anti-foul assembly 

takes about 2 work-hours for an 

estimated cost of $170 per helicopter 

and $18,700 for the U.S. fleet, per cycle. 

Cleaning, visually inspecting, and 

lubricating the rescue hoist cable takes 

about 2 work-hours for an estimated 

cost of $170 per helicopter and $18,700 

for the U.S. fleet, per cycle. Performing 

an operational check of the hoist kit 

speed limit switches and the electrical 

system takes about 0.5 work-hour for an 

estimated cost of $43 per helicopter and 

$4,730 for the U.S. fleet, per cycle. 

Performing a functional check of the 

cable cutter cartridge electrical system 

takes about 3 work-hours for an 

estimated cost of $255 per helicopter 

and $28,050 for the U.S. fleet, per cycle. 

The FAA has no way of determining 

the estimated costs to do allowable 

repairs based on the results of the CMR 

tasks. If required, replacing the float/life 

raft takes about 2 work-hours and parts 

cost about $5,000 for an estimated cost 

of $5,170 per float/life raft. Replacing 

the anti-foul assembly takes about 3 

work-hours and parts cost about $1,500 

for an estimated cost of $1,755 per antifoul assembly. Replacing a rescue hoist 

cable takes about 3 work-hours and 

parts cost about $3,150 for an estimated 

cost of $3,405 per rescue hoist cable. 

Overhauling a rescue hoist assembly 

costs about $83,000 and it takes about 

8 work-hours to remove and reinstall 

the hoist for a labor cost of $680, for a 

total estimated cost of $83,680 per 

helicopter, per overhaul cycle. 

Alternatively, replacing a hoist takes 

about 8 work-hours and parts cost about 

$200,000 for an estimated cost of 

$200,680 per helicopter, per 

replacement cycle. 

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.

Airworthiness Directives; Airbus SAS 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–09– 

14, which applied to certain Airbus SAS 

Model A350–941 and –1041 airplanes. 

AD 2020–09–14 required revising the 

existing airplane flight manual (AFM) to 

define a liquid-prohibited zone on the 

flight deck and provide procedures 

following liquid spillage on the center 

pedestal. AD 2020–09–14 also required 

installing a removable integrated control 

panel (ICP) cover on the flight deck and 

further revising the AFM to include 

instructions for ICP cover use. This AD 

requires installing a new, water-resistant 

ICP, which allows removing the ICP 

protective cover and the AFM revisions, 

as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference. This 

AD was prompted by development of a 

new, water-resistant ICP. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective July 29, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 29, 2021.
