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 certain The Boeing Company 

Model 747–8F and 747–8 series 

airplanes. The NPRM published in the 

Federal Register on November 15, 2021 

(86 FR 62960). The NPRM was 

prompted by a report of unusual flight 

instrument and EICAS behavior. In the 

NPRM, the FAA proposed to require 

inspecting the left, center, and right 

EFIS/EIU for certain serial numbers and 

replacement if necessary. The FAA is 

issuing this AD to address the possible 

display of incorrect information in the 

integrated display system (IDS). This 

condition, if not addressed, could result 

in reduced ability of the flightcrew to 

maintain continued safe flight and 

landing of the aircraft. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

three commenters, including Boeing, an 

individual, and Qatar Airways. The 

following presents the comments 

received on the NPRM and the FAA’s 

response. 

Request To Add Missing Serial Number 

to List of Affected EIUs 

Boeing and Qatar Airways requested a 

change to the proposed AD to add serial 

number 181MR2 to the list of affected 

EIUs. The commenters noted that the 

unit was inadvertently excluded from 

the affected serial number list in Figure 

1 of Boeing Alert Requirements Bulletin 

747–31A2565 RB, Revision 1, dated 

September 14, 2021. Qatar Airways 

noted that Boeing stated that the service 

information will be revised to include 

this EIU serial number. Qatar Airways 

added that including the affected EIU 

will ensure that affected part does not 

remain in service while eliminating the 

need to obtain an alternative method of 

compliance (AMOC) for accomplishing 

the actions required by this AD on that 

EIU. 

The FAA agrees with the request. The 

FAA has confirmed that this is an 

affected EIU and that the operator with 

the EIU having serial number 181MR2 is 

aware that it is affected and plans to 

replace the unit as required by this AD. 

The FAA has added paragraph (h)(2) of 

this AD to clarify that serial number 

181MR2 is also an affected EIU. The 

FAA has also redesignated paragraph (h) 

of the proposed AD as paragraph (h)(1) 

of this AD. 

Request for Information About 

Registered Airplanes 

An individual commenter asked how 

the information about the number of 

affected airplanes was gathered and how 

many non-U.S. registered planes are 

affected by the proposed AD. 

The FAA gathers this information 

from public records and from the 

airplane manufacturer. According to 

those sources, 68 of the airplanes 

affected by this AD are registered 

outside of the United States. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, and any 

other changes described previously, this 

AD is adopted as proposed in the 

NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 747–31A2565 

RB, Revision 1, dated September 14, 

2021. This service information specifies 

procedures for doing an inspection or a 

review of the maintenance and delivery 

records of the left, center, and right EIUs 

for any affected serial number, and 

replacing each affected EIU. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 8 airplanes of U.S. registry. The 


jspears on DSK121TN23PROD with RULES1
20700 Federal Register / Vol. 87, No. 68 / Friday, April 8, 2022 / Rules and Regulations 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection ............ 1 work-hour × $85 per hour = $85 ............................................................. $0 $85 $680 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the 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 

Replacement .......... Up to 3 work-hours × $85 per hour = Up to $255 ............................................... Up to $9,600 ......... Up to $9,855. 

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.

identify and correct an unsafe condition 

on an aviation product. The MCAI 

describes the unsafe condition as 

corrosion of the fuel system components 

located in the fuel gallery due to 

inadequate corrosion protection. This 

AD requires repetitively inspecting the 

fuel gallery for corrosion, rectifying any 

deficiencies, and accomplishing 

modifications to the fuel gallery system. 

The FAA is issuing this AD to address 

the unsafe condition on these products.

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 certain serial-numbered Viking 

Air Limited (type certificate previously 

held by Bombardier Inc. and de 

Havilland, Inc.) Model DHC–6–400 

airplanes. The NPRM published in the 

Federal Register on January 21, 2022 

(87 FR 3238). The NPRM was prompted 

by MCAI originated by Transport 

Canada, which is the aviation authority 

for Canada. Transport Canada issued AD 

CF–2018–07, dated February 23, 2018 

(referred to after this as ‘‘the MCAI’’), to 

address an unsafe condition on certain 

serial-numbered Viking Air Limited 

Model DHC–6–400 airplanes. The MCAI 

states: 

There have been reports of corrosion 

affecting components of the fuel system that 

are located in the fuel gallery because of 

inadequate corrosion protection. This 

condition affects only aeroplanes operating 

on floats. 

The effects of corrosion-related damage to 

fuel system components have included fuel
