(d) Subject 

Joint Aircraft System Component (JASC) 

Code 2800, Aircraft Fuel System. 

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as corrosion of 

fuel system components located in the fuel 

gallery due to inadequate corrosion 

protection. The FAA is issuing this AD to 

prevent corrosion-related damage to fuel 

system components, which could lead to fuel 

leaks, electrical arcing, loss of fuel boost 

pump function, and erroneous fuel quantity 

readings. This unsafe condition, if not 

corrected, could result in fuel starvation with 

loss of engine power and increased risk of an 

in-flight fire with consequent loss of airplane 

control. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions for Airplanes Operating 

on Floats on the Effective Date of This AD 

(1) Within 50 hours time-in-service (TIS) 

after the effective date of this AD or within 

3 months after the effective date of this AD, 

whichever occurs first, and thereafter at 

intervals not to exceed 125 hours TIS, do the 

following actions: 

(i) Remove all fuel gallery covers and rinse 

the fuel gallery with water. 

(ii) Inspect the fuel gallery for corrosion 

and, if there is any corrosion, take all 

necessary corrective actions before further 

flight by following Item D.15(2) of Special 

Inspection 3 in Temporary Revision No. 241, 

dated July 27, 2021, to the Viking DHC–6 

Inspection Requirements Manual, PSM 1–6–

(Viking SB V6/0044, Revision ‘B’). 

(h) Required Actions for Airplanes Modified 

To Operate on Floats After the Effective Date 

of This AD 

Within 12 months after the airplane is 

modified to operate on floats, regardless of 

whether the landing gear is later modified 

back to non-float landing gear, install the 

modifications applicable to your airplane 

serial number by following the 

Accomplishment Instructions, sections A. 

through E. in Viking SB V6/0044, Revision

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Leonardo S.p.a. Model AW109SP 

helicopters. This proposed AD was 

prompted by reports of corrosion inside 

the hoist support assembly (boom 

assembly) (affected part) that affects 

both the huck bolt heads (blind bolt 

fasteners) and the support surface. This 

proposed AD would require repetitive 

inspections of the external and internal 

surfaces of each affected part for 

cracking and corrosion and, depending 

on the findings, accomplishment of 

corrective actions, as specified in a 

European Union Aviation Safety Agency 

(EASA) AD, which is proposed for 

incorporation by reference (IBR). This 

proposed AD would also allow the 

installation of an affected part, provided 

certain instructions are followed. 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 March 7, 2022.

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0179, 

dated July 27, 2021 (EASA AD 2021– 

0179) to correct an unsafe condition for 

Leonardo S.p.A. Helicopters, formerly 

Finmeccanica S.p.A., AgustaWestland 

S.p.A., and Agusta S.p.A., Model 

AW109SP helicopters, all serial 

numbers. 

This proposed AD was prompted by 

reports of corrosion inside the hoist 

support assembly affecting both the 

huck bolt heads and the support surface. 

Investigation of the root cause for the 

corrosion is ongoing. The FAA is 

proposing this AD to address corrosion 

on the hoist support assembly. This 

condition, if not addressed, could affect 

the structural integrity of the hoist 

support assembly, leading to in-flight 

detachment of the hoist support and 

consequent damage to the helicopter, 

and injury to hoisted persons. See EASA 

AD 2021–0179 for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0179 requires 

repetitive inspections of the external 

and internal surfaces of each affected 

part for cracking and corrosion and, 

depending on the findings, 

accomplishment of corrective actions. If 

there is no evidence of corrosion on the 

interior surface of the boom torque tube 

or on the huck bolt heads, the corrective 

actions include spraying the interior 

surface with corrosion preventative 

compound around the hulk bolt heads 

from the forward and aft ends of the 

boom torque tube, and installing new 

tube plugs on both ends of the boom 

torque tube. If there is superficial 

corrosion on the interior surface of the 

boom torque tube or on the hulk bolt 

heads, the corrective actions include 

cleaning the corrosion, spraying the 

interior surface with corrosion 

preventative compound, and installing 

new tube plugs on both ends of the 

boom torque tube. If corrosion is found 

that is not superficial corrosion, the 

corrective action is repair or 

replacement of the boom torque tube. 

If cracking is observed on the external 

surface of the hoist support assembly 

the corrective action is replacement of 

the hoist support assembly. If only 

corrosion is found on the external 

surface of the hoist support assembly 

the corrective actions include cleaning 

the hoist support assembly. 

EASA AD 2021–0179 also allows 

installing an affected part, provided 

certain instructions are followed. 

This material 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 

These helicopters have been approved 

by EASA and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the 

European Union, EASA has notified the 

FAA about the unsafe condition 

described in its AD. The FAA is 

proposing this AD after evaluating all 

known relevant information and 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other helicopters of the same 

type design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2021–0179, described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate EASA AD 2021–0179 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2021–0179 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2021–0179 does not mean 

that operators need comply only with 

that section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2021–0179. 

Service information referenced in EASA 

AD 2021–0179 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0008 after the FAA final 

rule is published. 

Interim Action 

The FAA considers this proposed AD 

would be an interim action. If final 

action is later identified, the FAA might 

consider further rulemaking.

Federal Register / Vol. 87, No. 14 / Friday, January 21, 2022 / Proposed Rules 3243 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 40 

helicopters of U.S. Registry. The FAA 

estimates the following costs to comply 

with this proposed AD. 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Inspecting ........................................ 0.50 work-hour × $85 per hour = 

$42.50 per inspection cycle.

$0 $42.50 per inspection 

cycle.

$1,700 per inspection 

cycle. 

Installing new boom torque tube 

plugs.

0.25 work-hour × $85 per hour = 

$21.25.

5,044 $5,065.25 ...................... $202,610. 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the proposed inspection. The 

agency has no way of determining the 

number of aircraft that might need these 

replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Cleaning boom torque tube interior or exterior ............ 0.25 work-hour × $85 per hour = $21.25 ..................... $0 $21.25 

Replacing boom torque tube ........................................ 6 work-hours × $85 per hour = $510 ........................... 39,500 40,010 

Replacing hoist support assembly ............................... 6.50 work-hours × $85 per hour = $552.50 ................. 44,864 45,416.50 

The FAA has received no definitive 

data on which to base the cost estimates 

for the repairs specified in this proposed 

AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this proposed 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 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.
