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 747–8 and 747–8F series 

airplanes. The NPRM published in the 

Federal Register on August 25, 2023 (88 

FR 58120). The NPRM was prompted by 

a report indicating all six IDUs became 

blank when new flight plan data was 

entered in the FMS. It was determined 

that the Jeppesen airport map database 

(AMDB) had an error in the data 

structure tied to the Sydney airport 

(YSSY). The Electronic Flight 

Instrumentation System/Engine 

Indicating and Crew Alerting System 

(EICAS) Interface Units (EIUs) were 

unable to process the data structure, 

resulting in the displays blanking. 

Jeppesen subsequently fixed the AMDB 

to address the issue with YSSY and 

additional airport codes with an 

incorrect data structure. The current EIU 

software is unable to process incorrect 

data structures, which results in an EIU 

fault that cannot be cleared by the 

automated reset function of an EIU. 

After five resets the EIU defaults to shut 

down, resulting in all six IDUs, which 

are controlled by the EIUs, becoming 

blank. The EIU shut down can also 

result in an autothrottle disconnect and 

a degraded autopilot mode. The 

problem can occur on the ground when 

an airport code with an incorrect data 

structure in the AMDB is entered as an 

origin or destination and the flight plan 

is then put into operation by the FMS. 

In flight, the problem can occur when 

an airport code with an incorrect data 

structure in the AMDB is entered as the 

selected diversion airport. 

Additionally, the existing software 

does not provide an earlier indication of 

decaying airspeed during the landing 

phase for flap settings 25 and 30. The 

revised software provides an earlier 

threshold for triggering the low airspeed 

alerting EICAS Caution message. 

In the NPRM, the FAA proposed to 

require installing updated software. The 

unsafe condition, if not addressed, 

could result in loss of all flight deck 

displays (Primary Flight Display/EICAS/ 

Navigation Display, not including 

standby displays) combined with 

potential impact to the autopilot and 

auto-throttle functionality and lack of 

crew visibility of any subsequent system 

failures, which can prevent continued 

safe flight and landing; it could also 

result in inadequate alerting of decaying 

airspeed, unacceptably low airspeed, 

and loss of control of the airplane. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two commenters. Boeing stated it had 

no technical objection to the proposed 

AD. An anonymous individual 

commented generally on the 

manufacturer but provided no 

comments on the proposed actions or on 

the determination of the costs. 

Conclusion 

The FAA reviewed the relevant data, 

considered any 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 

products. Except for minor editorial 

changes, 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 747–31A2544 

RB, dated March 31, 2020. This service 

information specifies procedures for 

installing Integrated Display System 

(IDS) 804 software in each of the six 

Liquid Crystal Display (LCD) IDUs and 

in each of the three EIUs, if not already 

installed; followed by installing IDS 805 

software, which includes EIU software 

part number COL3F–0034–E805 and 

LCD software part number 3177–COL– 

DL8–05. 

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 section. 

Costs of Compliance 

The FAA estimates that this AD 

affects 19 airplanes of U.S. registry. The 

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 

Software Installation .......... Up to 6 work-hours × $85 

per hour = $510.

Up to $650 ........................ Up to $1,160 ..................... Up to $22,040. 

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 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 89, No. 32 / Thursday, February 15, 2024 / Rules and Regulations 11717 

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.

The FAA will consider all comments

Except for Confidential Business

following paragraph, and other

received, without change, to 

regulations.gov, including any personal

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to William McCully, 

Aviation Safety Engineer, FAA, 

International Validation Branch, FAA, 

1600 Stewart Ave., Suite 410, Westbury, 

NY 11590; phone (404) 474–5548; email 

william.mccully@faa.gov. Any 

commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2022–0072, 

dated April 26, 2022 (EASA AD 2022– 

0072), to correct an unsafe condition on 

Airbus Helicopters Model EC 225 LP 

helicopters, serial numbers 2650, 2651, 

2653, 2684, 2712, and 2796. 

This AD was prompted by a report 

that placards located on the RH side of 

the VIP flap door of the passenger cabin 

do not provide adequate door opening 

instructions necessary to operate the RH 

side VIP flap door in case of the 

helicopter ditching. The unsafe 

condition, if not addressed, could 

prevent jettisoning of the RH side VIP 

flap door during an emergency 

situation, possibly obstructing 

evacuation and resulting in injury to 

occupants. 

You may examine the EASA AD in 

the AD docket at regulations.gov under 

Docket No. FAA–2024–0039. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2022–0072 requires

placard, which correctly specifies
