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 787–8, 787–9, and 787–10 

airplanes. The NPRM published in the 

Federal Register on November 24, 2023 

(88 FR 82279). 


khammond on DSKJM1Z7X2PROD with RULES
76414 Federal Register / Vol. 89, No. 181 / Wednesday, September 18, 2024 / Rules and Regulations 

The NPRM was prompted by 

incidents related to erroneous A/T 

behavior during a balked landing with 

the A/T engaged, potential erroneous 

readings from the LRRA, and possible 

deficiencies in low airspeed protections 

and crew alerting systems. 

In the NPRM, the FAA proposed to 

require updating the TM and DCA OPS. 

The FAA is issuing this AD to address 

problems with the TM and DCA OPS, 

which could result in possible runway 

overrun or controlled flight into terrain. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from an 

individual who supported the NPRM 

without change. 

The FAA also received comments 

from four commenters, including Air 

Canada, American Airlines, Boeing, and 

Qatar Airways. The following presents 

the comments received on the NPRM 

and the FAA’s response to each 

comment. 

Request To Allow Use of Additional 

Service Information 

Air Canada and Qatar Airways 

requested that paragraph (g)(1) of the 

proposed AD be revised to also allow 

compliance using Boeing Alert 

Requirements Bulletin B787–81205– 

SB310018–00 RB, Issue 001, dated 

August 3, 2020, for aircraft on which 

installation of the DCA software update 

has already been done using Boeing 

Alert RB B787–81205–SB310018–00 RB, 

Issue 001, dated August 3, 2020. 

The FAA agrees with the commenters. 

There are no technical differences 

between Boeing Alert Requirements 

Bulletin B787–81205–SB310018–00 RB, 

Issue 002, dated July 15, 2021, and 

Boeing Alert Requirements Bulletin 

B787–81205–SB310018–00 RB, Issue 

001, dated August 3, 2020. The FAA has 

changed paragraph (g)(1) to include 

Boeing Alert RB B787–81205– 

SB310018–00 RB, Issue 001, dated 

August 3, 2020, as acceptable for use 

before the effective date of this AD. 

American Airlines and Qatar Airways 

requested that the proposed AD be 

revised to ensure that subsequent 

approved versions of DCA OPS and TM 

OPS software will still be compliant 

with the proposed AD. American 

Airlines requested that paragraph (g) of 

the proposed AD be revised to read as 

follows: 

For airplanes identified in paragraph (g) of 

this AD: Within 6 months after the effective 

date of this AD, install DCA OPS P/N 

COL47–0014–0031 or later-approved 

software version and TM OPS P/N HNP55– 

AL12–5008 or later-approved software 

version at the locations specified in the 

Service Bulletins. Both the installation and 

the check must be done in accordance with 

a method approved by the Manager, AIR– 

520, Continues Operation Safety Branch, 

FAA. Later approved software versions are 

those Boeing software versions that are 

approved as a replacement for the DCA OPS 

P/N COL47–0014–0031 and TM OPS P/N 

HNP55–AL12–5008 and are approved as part 

of the type design by the FAA or by The 

Boeing Company Organization Designation 

Authorization (ODA). 

The FAA infers this request is to 

reduce the need for alternative methods 

of compliance (AMOCs) for subsequent 

(newer) approved versions of DCA OPS 

and TM OPS software. 

The FAA partially agrees with the 

commenters. The FAA agrees that 

without the usage of the terminology ‘‘or 

later approved software’’ or some 

variation of the wording that allows the 

use of later-approved software, 

historically ADs related to software 

changes that did not have this wording 

have resulted in multiple AMOCs for 

software updates. The FAA disagrees 

with the need to add ‘‘or later approved 

software’’ language to paragraph (g) of 

this AD because this provision is found 

in Boeing Requirements Bulletins B787– 

81205–SB310018–00 RB, Issue 002, 

dated July 15, 2021, and Boeing Alert 

Requirements Bulletin B787–81205– 

SB340053–00 RB, Issue 001, dated 

November 16, 2022, which are required 

by paragraphs (g)(1) and (2) of this AD, 

respectively. The FAA has not changed 

this AD in regard to this comment. 

Requests To Clarify Terms in the NPRM 

Boeing requested that ‘‘throttle 

malfunction’’ be replaced with 

‘‘erroneous autothrottle (A/T) behavior’’ 

in the Summary and Background of the 

NPRM, and paragraph (e) in the 

proposed AD, because the description 

incorrectly describes what occurred. 

The FAA agrees that erroneous A/T 

behavior is a more accurate description 

of the occurrence. The full Background 

section is not restated in this final rule. 

The FAA has changed the Summary of 

the NPRM and paragraph (e) of this AD 

accordingly. 

Boeing also requested that in the 

Background section, third paragraph, 

‘‘flight management function (FMF)’’ be 

replaced with ‘‘Flight Management 

Function (FMF)/Thrust Management 

Function (TMF) Block Point (BP) 4.0’’ 

because the behavior was due to the 

design changes included in the thrust 

management operation software and 

flight management BP 4.0. 

The FAA agrees that FMF/TMF BP 4.0 

more accurately describes the associated 

change; however, the full text of the 

NPRM Background section is not 

repeated in the final rule, so no further 

change is necessary to this final rule. 

Boeing further requested that the 

Background section, sixth paragraph, be 

revised to read ‘‘Airplanes with version 

TMF software BP 4 installed, the A/T 

system is engaged during a manual goaround or missed approach . . .’’ 

because the behavior seen during a 

balked landing was introduced with 

TMF BP 4.0. 

The FAA agrees that the issue of 

erroneous A/T behavior was introduced 

by FMF/TMF BP 4; however, the full 

text of the NPRM Background section is 

not repeated in the final rule, so no 

further change is necessary to this final 

rule. 

Request To Delete Terms 

Boeing requested that the FAA revise 

the NPRM to delete any reference 

related to ‘‘possible deficiencies in low 

airspeed protections and crew alerting 

systems,’’ ‘‘crew alerting systems,’’ 

‘‘displays and crew alerting (DCA),’’ 

‘‘crew alerting (DCA) operational 

software (OPS),’’ ‘‘install and check 

DCA software,’’ and ‘‘The FAA 

reviewed Boeing Alert Requirements 

Bulletin B787–81205–SB310018–00 RB, 

Issue 002, dated July 15, 2021. This 

service information specifies procedures 

for installing updated DCA OPS 

software and doing a software 

configuration check’’ because the design 

change included in TMF 4.1 (TMF BP 

4.1) to address 20–PAD–0048 

(Erroneous A/T Behavior During Balked 

Landing) and 20–AD–0054 (Erroneous 

Low Range Radio Altimeter Readings) is 

not dependent on a DCA OPS update. 

Boeing also requested that the FAA 

revise the NPRM to delete the following 

statements: 

The FAA has reviewed a report of the 

investigation of an accident that revealed 

deficiencies in low airspeed protections and 

crew alerting systems on Model 777 and 787. 

Further, airplanes with versions of FMF 

software prior to BP 4 are susceptible to 

situations where the flightcrew may believe 

the airplane systems will prevent the 

airplane from having too low an airspeed for 

its flight condition, when in fact the systems 

do not offer that protection. This can also 

result in a CFIT event. 

Boeing requested these deletions 

because the autothrottle low airspeed 

enhancements were implemented in 

FMF/TMF BP 4.0. 

The FAA acknowledges that the 

changes associated with TMF BP 4.1 

needed to address the issue of erroneous 

A/T behavior and erroneous LRRA 

readings are not dependent upon a DCA 

OPS update, but the FAA disagrees with 

removing any reference to the 

‘‘deficiencies in low airspeed 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 89, No. 181 / Wednesday, September 18, 2024 / Rules and Regulations 76415 

protections and crew alerting systems’’ 

or ‘‘crew alerting (DCA) OPS.’’ Some 

changes associated with TMF BP 4.1 are 

to fix an unsafe condition (A/T issue) 

introduced by the previous TMF update 

BP 4. The FAA had intended to mandate 

TMF BP 4 (in combination with a DCA 

OPS update) to address the unsafe 

condition of insufficient low airspeed 

protections and crew alerting systems 

but had to postpone AD action until 

TMF BP 4.1 was available over three 

years later. While TMF BP 4.1 includes 

the TMF BP 4 updates addressing low 

airspeed protections, this is the first 

time the FAA has mandated 

requirements to address this unsafe 

condition. The FAA has not changed 

this AD in regard to this comment. 

The ‘‘Related Service Information 

Under 1 CFR part 51’’ section of the 

NPRM described the procedures 

specified in Boeing Alert Requirements 

Bulletin B787–81205–SB310018–00 RB, 

and then added that the FAA ‘‘also’’ 

reviewed Boeing Alert Requirements 

Bulletin B787–81205–SB340053–00 RB, 

Issue 001, dated November 16, 2022, 

which specifies procedures for 

installing updated TM OPS software. 

Boeing requested that the word ‘‘also’’ 

be deleted because there is only one 

Boeing Alert Requirement Bulletin 

associated with Thrust Management BP 

4.1. 

The FAA disagrees with the request. 

The documents cited in this section of 

the NPRM (and this final rule) are 

required sources of service information 

for the requirements of this AD. The two 

documents include different actions 

(one for installing updated DCA OPS 

software and the other for installing 

updated TM OPS software), but both are 

necessary to address the unsafe 

conditions identified in this final rule. 

The FAA has not changed this final rule 

as a result of this comment. 

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, 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 Material Under 1 CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin B787–81205– 

SB310018–00 RB, Issue 002, dated July 

15, 2021. This material specifies 

procedures for installing updated DCA 

OPS software and doing a software 

configuration check. 

The FAA also reviewed Boeing Alert 

Requirements Bulletin B787–81205– 

SB340053–00 RB, Issue 001, dated 

November 16, 2022. This material 

specifies procedures for installing 

updated TM OPS software and doing a 

software configuration check. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 125 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 

Install and check DCA software ..................... 3 work-hours × $85 per hour = $255 ............. * $0 $255 $31,875 

Install and check TM software ........................ 4 work-hours × $85 per hour = $340 ............. * 0 340 42,500 

* Boeing has confirmed that there is no charge for the software. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this 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 

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.
