11186 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules 

(e) Reason 

This AD was prompted by a report 

indicating that the left-hand main landing 

gear (MLG) collapsed after touchdown, 

causing severe damage to the airplane. The 

FAA is issuing this AD to address abnormal 

behavior of the MLG hydraulic transfer valve 

due to a restriction in hydraulic flow, which 

could cause the MLG hydraulic transfer valve 

to not function properly and fail to retract, 

extend, or lock the MLG, and possibly result 

in MLG collapse following landing and 

consequent damage to the airplane and injury 

to occupants. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, European Union Aviation 

Safety Agency (EASA) AD 2020–0233, dated 

October 14, 2020 (EASA AD 2020–0233). 

(h) Exceptions to EASA AD 2020–0233 

(1) Where EASA AD 2020–0233 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(2) The ‘‘Remarks’’ section of EASA AD 

2020–0233 does not apply to this AD. 

(i) Other FAA AD Provisions 

The following provisions also apply to this 

AD:

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

The Boeing Company Model 737–100, 

–200, –200C, –300, –400, and –500 

series airplanes. This proposed AD was 

prompted by a report indicating that a 

crack was found on the splice angle 

flange that is attached to the station 

(STA) 540 bulkhead in the area between 

certain stringers. This proposed AD 

would require repetitive surface high 

frequency eddy current (HFEC) 

inspections at the radius of the left- and 

right side of the STA 540 bulkhead 

splice angle for any cracking and 

applicable on-condition actions. 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 April 12, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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 NPRM 

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 NPRM, 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

public docket for this rulemaking. 

Discussion 

The FAA has received a report from 

Boeing indicating that a crack was 

found on the splice angle flange that is 

attached to the STA 540 bulkhead in the 

area between stringer 21 to stringer 22. 

The crack was found during the 

accomplishment of Supplemental 

Structural Inspection Document (SSID) 

F–25A on a Model 737–300 airplane. 

The airplane had accumulated 80,634 

flight hours and 62,768 flight cycles at 

the time of the crack finding. This 

condition, if not addressed, could result 

in the inability of a principal structural 

element to sustain limit load and could 

adversely affect the structural integrity 

of the airplane; in addition, such 

cracking could lead to adjoining parts 

cracking and a potential fuel leak and 

consequent fire. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Boeing Alert 

Requirements Bulletin 737–57A1347 

RB, dated July 29, 2020. The service 

information describes procedures for 

repetitive surface HFEC inspections at 

the radius of the left- and right side of 

the STA 540 bulkhead splice angle for 

any cracking and applicable oncondition actions. On-condition actions 

include repair or replacement. 

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. 

Explanation of Applicability 

Model 737 airplanes having line 

numbers 1 through 291 have a limit of 

validity (LOV) of 34,000 total flight 

cycles, and the actions proposed in this 

NPRM, as specified in Boeing Alert 

Requirements Bulletin 737–57A1347 

RB, dated July 29, 2020, would be 

required at a compliance time occurring 

after that LOV. Although operation of an 

airplane beyond its LOV is prohibited 

by 14 CFR 121.1115 and 129.115, this 

NPRM would include those airplanes in 

the applicability so that these airplanes 

are tracked in the event the LOV is 

extended in the future. 

FAA’s Determination 

The FAA is proposing this AD 

because the agency evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishment of the actions 

identified in Boeing Alert Requirements 

Bulletin 737–57A1347 RB, dated July 

29, 2020, described previously, except 

for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. 

For information on the procedures 

and compliance times, see this service 

information at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2021– 

0026. 

Explanation of Requirements Bulletin 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee (AD ARC), to 

enhance the AD system. One 

enhancement is a process for annotating 

which steps in the service information 

are ‘‘required for compliance’’ (RC) with 

an AD. Boeing has implemented this RC 

concept into Boeing service bulletins. 

In an effort to further improve the 

quality of ADs and AD-related Boeing 

service information, a joint process 

improvement initiative was worked 

between the FAA and Boeing. The 

initiative resulted in the development of 

a new process in which the service 

information more clearly identifies the 

actions needed to address the unsafe 

condition in the ‘‘Accomplishment 

Instructions.’’ The new process results 

in a Boeing Requirements Bulletin, 

which contains only the actions needed 

to address the unsafe condition (i.e., 

only the RC actions). 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 117 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Repetitive surface HFEC 

inspections.

7 work-hour × $85 per hour = $595 per inspection cycle.$0 $595 per inspection 

cycle.

$69,615 per inspection 

cycle. 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required. The 

FAA has no way of determining the 

number of aircraft that might need these 

on-condition actions: 


khammond on DSKJM1Z7X2PROD with PROPOSALS
11188 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

Up to 53 work-hour × $85 per hour = Up to $4,505 (replacement) ....... Up to $1,000 .................................. Up to $5,505. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition repair specified in 

this proposed AD. 

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

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Dassault Aviation Model 

FALCON 7X airplanes and Model 

FALCON 2000EX airplanes. This 

proposed AD was prompted by a report 

that non-certified ANCRA seat tracks 

were installed on some airplanes and 

that those seat tracks might not sustain 

required loads during an emergency 

landing. This proposed AD would 

require replacement of certain ANCRA 

seat tracks with certified (Brownline) 

seat tracks, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference. 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 April 12, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

all comments received by the closing 

date and may amend the proposal 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this proposed 

AD. 

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 NPRM 

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 NPRM, 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 

NPRM. Submissions containing CBI 

should be sent to Tom Rodriguez, 

Aerospace Engineer, Large Aircraft 

Section, International Validation 

Branch, FAA, 2200 South 216th St., Des 

Moines, WA 98198; telephone and fax 

206–231–3226; email tom.rodriguez@

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 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0188, dated August 24, 2020 

(EASA AD 2020–0188) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for certain Dassault Aviation Model 

FALCON 7X airplanes and Model 

FALCON 2000EX airplanes. 

This proposed AD was prompted by 

a report that non-certified ANCRA seat 

tracks were installed on some airplanes 

and that those seat tracks might not 

sustain required loads during an 

emergency landing. The FAA is 

proposing this AD to address seat tracks 

that could fail and lead to seat 

detachment during an emergency 

landing, which could result in injury to 

airplane occupants and prevent 

evacuation of the airplane. See the
