Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2019–02– 

03, which applied to all The Boeing 

Company Model 787–8, 787–9, and 

787–10 airplanes. AD 2019–02–03 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

This AD retains the requirements of AD 

2019–02–03 and requires incorporation 

of an airworthiness limitation that 

applies only to certain airplanes. This 

AD also requires replacing or modifying 

certain engine fire control panels, which 

terminates the revised airworthiness 

limitation added in this final rule when 

a certain condition is met. Since the 

FAA issued AD 2019–02–03, the 

manufacturer has developed a new fire 

handle design that will eliminate the 

need for the airworthiness limitations 

required by AD 2019–02–03. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 30, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 30, 2021.

SUPPLEMENTARY INFORMATION: 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2019–02–03, 

Amendment 39–19550 (84 FR 2437, 

February 7, 2019) (AD 2019–02–03). AD 

2019–02–03 applied to all The Boeing 

Company Model 787–8, 787–9, and 

787–10 airplanes. The NPRM published 

in the Federal Register on July 15, 2020 

(85 FR 42749). The NPRM was 

prompted by reports of warpage of 

internal engine fire handle components 

that can cause binding and prevent 

proper operation, and by the 

development of a new fire handle 

design that will eliminate the need for 

the airworthiness limitations required 

by AD 2019–02–03. The NPRM 

proposed to retain the requirements of 

AD 2019–02–03 and to require 

incorporation of an airworthiness 

limitation that applies only to certain 

airplanes. The NPRM also proposed to 

require replacing or modifying certain 

engine fire control panels, which would 

terminate the revised airworthiness 

limitation added in this final rule when 

a certain condition is met. The FAA is 

issuing this AD to address a latent 

failure of the engine fire handle, which 

could result in the inability to 

extinguish an engine fire that, if 

uncontrollable, could lead to wing 

failure. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this AD. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Request To Expand Approved 

Alternative Methods of Compliance 

(AMOCs) 

Boeing asked that paragraph (o)(4) of 

the proposed AD (paragraph (p)(4) of 

this AD), which specifies ‘‘AMOCs 

approved previously for AD 2019–02–03 

are approved as AMOCs for the 

corresponding provisions of paragraph 

(g) of this AD,’’ also include approval of 

AMOCs for the corresponding 

provisions of paragraph (k) of the 

proposed AD. Boeing stated that 

approved AMOC RA–19–00263 (Boeing 

letter requesting an AMOC for AD 2019– 

02–03) provides inspection instructions 

equivalent to Airworthiness Limitation 

28–AWL–FIRE in figure 1 to paragraph 

(g) of the proposed AD. Boeing added 

that the inspection instructions of 28– 

AWL–FIRE in figure 1 to paragraph (g) 

of the proposed AD and in figure 2 to 

paragraph (k) of the proposed AD are 

identical. 

The FAA partially agrees with the 

commenter’s request. The FAA 

previously approved Boeing Alert 

Requirements Bulletin B787–81205– 

SB260007–00 RB, Issue 001, dated 

February 22, 2019, as an AMOC to the 

requirements of paragraph (g) of AD 

2019–02–03. The inspection 

instructions provided in Boeing Alert 

Requirements Bulletin B787–81205– 

SB260007–00 RB, Issue 001, dated 

February 22, 2019, are equivalent to 28– 

AWL–FIRE in figure 1 to paragraph (g) 

of this AD and in figure 2 to paragraph 

(k) of this AD. Because paragraph (k) is 

a new requirement of this AD, the FAA 

has instead added the action as an 

alternative terminating action, 

paragraph (l) of this AD, for the 

repetitive inspections for airplanes 

equipped with an engine fire control 

panel having part number (P/N) 

Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 10791 

412600–001 or an engine fire shutoff 

switch having P/N 417000–101 or P/N 

417000–102. 

Request To Revise Parts Installation 

Prohibition Paragraph or Extend 

Compliance Time 

American Airlines, All Nippon 

Airways (ANA), and United Airlines 

asked that the FAA revise paragraph (n) 

of the proposed AD to continue to 

allow, for a limited time, the installation 

of the engine fire handle with the part 

numbers on which an unsafe condition 

has been identified after the effective 

date of the AD. American Airlines and 

United Airlines asked that installing the 

parts be allowed for 15 months after the 

effective date of the AD, which is 

consistent with the referenced service 

information. ANA asked that it be 

allowed to install the parts until the 

engine fire handle with new part 

numbers is installed in accordance with 

paragraph (i) of the proposed AD. ANA 

also asked that the compliance time 

specified in paragraph (i) of the 

proposed AD be extended to 24 months 

after the effective date of the AD. 

American Airlines stated that this 

change is necessary because the 

repetitive inspections of the engine fire 

handle with the part numbers on which 

an unsafe condition has been identified 

remain in place until those part 

numbers are replaced by the new part 

numbers. American Airlines added that 

they would need a full panel or two new 

switches if there were findings of failed 

fire handles because they can’t mix old 

and new parts. American Airlines, 

ANA, and United Airlines expressed 

their concern regarding parts 

availability due to limited supply. ANA 

stated that the supply of the engine fire 

handles with new part numbers is 

insufficient worldwide due to the 

Coronavirus Disease 2019 (COVID–19). 

The FAA partially agrees with the 

commenters’ requests, based on the 

limited supply of new part numbers 

available due to extenuating 

circumstances. The FAA has received a 

number of reports of failed engine fire 

handles found during the repetitive 

inspections. The frequency of failures 

found in service, and the provisions of 

the ‘‘Parts Installation Prohibition’’ of 

paragraph (n) of the proposed AD, could 

have forced operators to install the new 

part numbers from a limited supply 

before reaching the compliance time in 

paragraph (i) of this AD. Furthermore, as 

American Airlines stated, the repetitive 

inspections required by 28–AWL–FIRE 

remain in place until a fire handle with 

new part numbers is installed. The 

repetitive inspections do not eliminate 

the latent failure of the engine fire 

handle, but they will limit the number 

of flights the airplanes can operate with 

a failed engine fire handle. Since 

paragraph (n) of the proposed AD would 

have applied to all airplanes including 

those airplanes delivered with the 

engine fire control panel having the new 

part number required by paragraph (i) of 

this AD, and since it is necessary to 

prohibit the replacement of the new part 

number with the old part number for 

those airplanes that are not covered by 

paragraph (i) of this AD, the FAA has 

revised paragraph (o) of this AD 

(paragraph (n) of the proposed AD) to 

include an exception for airplanes 

identified in Boeing Requirements 

Bulletin B787–81205–SB260008–00 RB, 

Issue 001, dated March 10, 2020. For 

airplanes affected by paragraph (i) of 

this AD, once operators comply with the 

actions required by paragraph (i) of this 

AD by installing parts with new part 

numbers, operators must continue to 

maintain the airplane configuration 

compliant with the AD requirements. 

For airplanes delivered with the fire 

control panel having the new part 

number, paragraph (o) of this AD 

prohibits the replacement of the new 

part numbers with the old part numbers 

on which the unsafe condition was 

identified. 

The FAA does not agree with ANA’s 

request to revise the compliance time in 

paragraph (i) of this AD to 24 months. 

Since the level of impact of parts supply 

may vary for each operator, we are 

unable to determine an appropriate 

change to the compliance time in 

paragraph (i) of this AD that will result 

in a minimal impact on safety and on 

operators’ ability to comply with the AD 

requirements. Therefore, operators that 

encounter limited parts supply that 

could hinder the ability to meet the 

requirements of paragraph (i) of this AD 

within the compliance time indicated 

should request an AMOC to extend this 

compliance time. If data are provided to 

show that the extended compliance time 

addresses the unsafe condition, 

operators may request approval of an 

AMOC under the provisions of 

paragraph (p) of this AD. The FAA has 

not changed this AD regarding this 

issue. 

Request To Revise Airworthiness 

Limitation 28–AWL–FIRE 

The Air Line Pilots Association, 

International (ALPA) asked that the 

FAA revise Airworthiness Limitation 

28–AWL–FIRE to remove the language 

that allows the flightcrew to perform an 

operational check of the engine fire 

handle. ALPA stated that because the 

proposed AD retains the actions 

required by AD 2019–02–03, the 

proposed AD also retains the allowance 

for the flightcrew to perform the engine 

fire handle operational check in a 

manner approved by the principal 

operations inspector in lieu of being 

performed by specifically trained 

maintenance personnel per the 

procedures in 28–AWL–FIRE. ALPA 

previously highlighted concern with the 

flightcrew conducting the check 

required by AD 2019–02–03, and 

reiterated that concern in comments on 

the NPRM. ALPA noted that without 

specific training to flightcrews, the 

opportunity exists for the operational 

check to be performed inaccurately. 

ALPA concluded that to ensure that the 

check is effective until the terminating 

action is accomplished, consistent 

procedures should be followed and 

documented by appropriately trained 

maintenance personnel, as specified in 

the proposed AD. 

The FAA does not agree with the 

commenter’s request. Airworthiness 

Limitation 28–AWL–FIRE includes an 

allowance for the flightcrew to perform 

an operational check of the engine fire 

handle since the inspection interval is 

relatively short and the inspection 

procedure is relatively straightforward. 

Based on this allowance, operators can 

develop the procedures for the 

flightcrew to perform an operational 

check in a timely manner. Operators 

must ensure that the operational check 

required by 28–AWL–FIRE is accurately 

performed by the flightcrew in order for 

the procedures to be approved by the 

principal operations inspector. The FAA 

has not changed this AD in this regard. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously, 

and minor editorial changes. The FAA 

has determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

The FAA also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing 

Requirements Bulletin B787–81205– 

SB260008–00 RB, Issue 001, dated 

March 10, 2020. The service information 

describes procedures for replacing the 

10792 Federal Register / Vol. 86, No. 34 / Tuesday, February 23, 2021 / Rules and Regulations 

engine fire control panel with a new or 

modified panel. 

The FAA also reviewed Boeing 

Requirements Bulletin B787–81205– 

SB260007–00 RB, Issue 001, dated 

February 22, 2019. The service 

information describes procedures for 

performing repetitive operational checks 

of the engine fire handle. 

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 the ADDRESSES section. 

Costs of Compliance 

The FAA estimates that this AD 

affects 122 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2019–02–03 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workhours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new maintenance or 

inspection program revision to be 

$7,650 (90 work-hours × $85 per workhour). 

ESTIMATED COSTS FOR REQUIRED REPLACEMENT OR MODIFICATION

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement or modification .......................... 2 work-hours × $85 per hour = $170 ............. $5,000 $5,170 $630,740 

According to the manufacturer, some 

or all of the costs of this AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. The FAA does not control 

warranty coverage for affected 

individuals. As a result, the FAA has 

included all known costs in our cost 

estimate. 

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 has determined that 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.

–1B74/75/P2, –1B76/P2, and –1B76A/ 

P2 model turbofan engines. This AD 

was prompted by a report of a crack in 

the outer fuel manifold causing fuel 

leakage. This AD requires initial and 

repetitive visual inspections of the 

cushioned loop clamp (p-clamp) and, 

depending on the results of the 

inspection, a spot fluorescent penetrant 

inspection (FPI) of the outer fuel 

manifold. Depending on the results of 

the FPI, this AD may require 

replacement of the outer fuel manifold. 

This AD also requires initial and 

repetitive replacements of the p-clamp. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

DATES: This AD is effective March 30, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD
