Air Transport Association (ATA) of
America Code 57, Wings.
(e) Unsafe Condition
This AD was prompted by reports of bolt
rotation in the engine drag fitting joint and
fastener heads and cracks found in the skin
of the fastener holes, and the need to reduce
the compliance time for certain groups. The
FAA is issuing this AD to address cracking
in the wing upper skin and forward drag
fittings, which could lead to a compromised
upper link and reduced structural integrity of
the engine strut, and possible separation of
a strut and engine from the airplane during
flight.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

Background
The FAA issued AD 2020–12–08,
Amendment 39–21143 (85 FR 36312,
June 16, 2020) (AD 2020–12–08), for
Embraer S.A. (type certificate previously
held by Empresa Brasileira de
Aerona´utica S.A.) Model EMB–505
airplanes, all serial numbers. AD 2020–
12–08 was prompted by reports of
corrosion in the mass-balance weights of
the flight control surfaces and a
determination that new airworthiness
limitations are necessary. AD 2020–12–
08 was based on mandatory continuing
airworthiness information (MCAI)
issued by the Ageˆncia Nacional de
Aviac¸a˜o Civil (ANAC), which is the
aviation authority for Brazil. ANAC
issued Brazilian Emergency AD No.
2020–01–01, dated January 9, 2020, to
address the unsafe condition on all
Embraer S.A. Model EMB–505
airplanes.
AD 2020–12–08 requires, for certain
serial-numbered airplanes, inspecting
the mass-balance weights of the flight
control surfaces and their attachment
PO 00000
Frm 00005
Fmt 4702
Sfmt 4702
parts for corrosion and fragmentation,
and corrective actions if necessary,
including sending inspection results to
Embraer. For all airplanes, AD 2020–12–
08 requires revising the airworthiness
limitation section of the maintenance
manual or instructions for continued
airworthiness to incorporate new
airworthiness limitations.
The FAA issued AD 2020–12–08 to
address corrosion in the mass-balance
weights of the flight control surfaces.
The unsafe condition, if not addressed,
could result in loss of mass or the
detachment of the mass-balance
weights, resulting in an unbalanced
control surface, which could lead to
flutter and loss of airplane control.
Actions Since AD 2020–12–08 Was
Issued
Since the FAA issued AD 2020–12–
08, ANAC superseded Brazilian
Emergency AD No. 2020–01–01, dated
January 9, 2020, and issued Brazilian
AD No. 2020–09–01, dated September 8,
2020 (referred to after this as ‘‘the
MCAI’’). The MCAI states:
It has been found the occurrence of
corrosion in the mass-balance weights of the
control surfaces. The corrosion may lead to
loss of mass or detachment of the massbalance weights, resulting in an unbalance
control surface, which, in conjunction with
certain flight conditions, could lead to flutter
and possible loss of airplane control.
Since this condition may occur in other
airplanes of the same type and affects flight
safety, a corrective action is required. Thus,
sufficient reason exists to request compliance
with this [ANAC] AD in the indicated time
limit.
After [ANAC] EAD 2020–01–01 was
released, a reassessment of the unsafe
condition by Embraer and, subsequently, the
SB 505–55–0004, revisions 0 and 1, dated
March 25th, 2020 and June 24, 2020,
respectively, expanding the list of affected
aircraft serial numbers (S/Ns) as well as
inserting more restrictive criteria to
determine the replacement of affected P/Ns.
Therefore, this [ANAC] AD retains the
requirements of [ANAC] EAD 2020–01–01,
which is superseded, and incorporates new
applicable aircraft S/Ns and new criteria for
the replacement of affected P/Ns.
You may examine the MCAI at
https://www.regulations.gov by
searching for and locating Docket No.
FAA–2020–1073.
Comments on AD 2020–12–08
The FAA issued AD 2020–12–08 as a
final rule; request for comments. The
FAA received comments on AD 2020–
12–08 from Flexjet LLC (Flexjet), an
individual, and two anonymous
commenters.
Flexjet and an anonymous commenter
requested that AD 2020–12–08 allow
credit for previous actions using

Federal Register / Vol. 86, No. 172 / Thursday, September 9, 2021 / Proposed Rules
Embraer Alert Service Bulletin SB505–
55–A004, Revision 5, dated December
12, 2019 (SB505–550A004 R5), as that
service bulletin is not listed in
paragraph (l) of AD 2020–12–08 (‘‘Credit
for Previous Actions’’ paragraph).
The FAA notes that the actions of AD
2020–12–08 must be done in accordance
with SB505–55A004 R5. Paragraph (f) of
AD 2020–12–08 requires compliance
‘‘unless already done.’’ Thus, AD 2020–
12–08 already allows operators to take
credit for using SB505–55A004 R5 if
done before the effective date of the AD.
Flexjet and an anonymous commenter
requested AD 2020–12–08 include
Embraer Service Bulletin SB505–55–
0004, dated March 24, 2020 (SB505–55–
0004), as this service bulletin addresses
the worldwide fleet.
The FAA agrees. SB505–55–0004
includes additional actions, which are
required by ANAC AD No. 2020–09–01,
dated September 8, 2020. This proposed
AD would include those additional
requirements.
The individual commenter noted that
SB505–55–0004, SB505–55A004 R5,
and Embraer Alert Service Bulletin
SB505–55–A004, Revision 06, dated
March 25, 2020, apply to different
ranges of serial numbers and requested
the FAA clarify the correct serial
numbers for AD 2020–12–08.
AD 2020–12–08 applies to all Model
EMB–505 airplanes, regardless of serial
number. However, only those airplanes
with a serial number in SB505–55A004
R5 are required to do the actions in
paragraphs (h) and (k) of AD 2020–12–
08.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Embraer Alert
Service Bulletin SB505–55–A004,
Revision 06, dated March 25, 2020. This
service information specifies procedures
for inspecting the mass-balance weights
of the flight control surfaces and their
respective attachment parts for
corrosion and fragmentation, and
performing corrective actions on certain
serial-numbered Model EMB–505
airplanes. Corrective actions include
installation of a stainless steel massbalance, replacement of the massbalance, and replacement of attachment
parts.
The FAA also reviewed Embraer
Service Bulletin SB505–55–0004,
Revision 01, dated June 24, 2020. This
service information specifies
procedures, for certain airplanes, for
cleaning and weighing the elevator,
aileron, and rudder mass-balances, and
installing or replacing the mass-balances
(includes replacing attachment parts), as
applicable, and for certain elevator
mass-balances for certain airplanes,
replacing those elevator mass-balances
(includes replacing attachment parts).
Embraer has also issued Alert Service
Bulletin SB505–55–A004, Revision 5,
dated December 12, 2019, which the
Director of the Federal Register
approved for incorporation by reference
as of July 1, 2020 (85 FR 36312, June 16,
2020).
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.
Other Related Service Information
Embraer has issued Embraer Service
Bulletin SB505–55–0004, dated March
25, 2020. The actions specified in
Embraer Service Bulletin SB505–55–
0004, dated March 25, 2020, are the
same as those specified in Embraer Alert
Service Bulletin SB505–55–0004,
Revision 01, dated June 24, 2020;
however, Embraer Alert Service Bulletin
SB505 55–0004, Revision 01, dated June
24, 2020, was issued to add serialnumbered airplanes to the effectivity.
No additional work is required for
airplanes on which Embraer Service
Bulletin SB505–55–0004, dated March
25, 2020, has been accomplished.
FAA’s Determination
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with this
State of Design Authority, it has notified
the FAA of the unsafe condition
described in the MCAI and service
information described above. The FAA
is issuing this NPRM after determining
that the unsafe condition described
previously is likely to exist or develop
on other products of the same type
design.
Proposed AD Requirements in This
NPRM
This proposed AD would retain the
actions required by AD 2020–12–08 and
would require, for certain airplanes,
cleaning and weighing the elevator,
aileron, and rudder mass-balances, and
installation or replacement, as
applicable of the mass-balances. This
proposed AD would also remove the
reporting required by AD 2020–12–08.
For the retained requirement to revise
the airworthiness limitations section
(ALS) of the existing maintenance
manual or instructions for continued
airworthiness in paragraph (i) of this
proposed AD, the FAA notes the
inspection tasks are part of Chapter 5 of
the aircraft maintenance manual—Part
III—scheduled maintenance
requirements. This proposed AD would
require these tasks as new airworthiness
limitations.
Differences Between This Proposed AD
and the Service Information
Embraer Alert Service Bulletin
SB505–55–A004, Revision 5, dated
December 12, 2019; and Revision 06,
dated March 25, 2020, contain
procedures for inspecting for the
integrity of the mass-balance weights of
flight control surfaces and their
attachment parts. This proposed AD
would not include that requirement.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 392
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:

The FAA has included all known
costs in this cost estimate. According to
the manufacturer, however, some of the
costs of this proposed 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.
lotter on DSK11XQN23PROD with PROPOSALS1
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 that the 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.

Airworthiness Directives; Embraer S.A. (Type Certificate
Previously Held by Empresa Brasileira de Aeron[aacute]utica S.A.)

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2020-12-08, which applies to all Embraer S.A. Model EMB-505 airplanes.
AD 2020-12-08 requires inspections of the mass-balance weights of the
elevators, ailerons, and rudder (flight control surfaces) and their
attachment parts, and corrective actions if necessary, and revising the
airworthiness limitation section of the maintenance manual or
instructions for continued airworthiness to incorporate new
airworthiness limitations. Since AD 2020-12-08 was issued, the FAA has
determined that new applicable airplane serial numbers and new criteria
for the replacement of affected parts must be required in order to
address the unsafe condition. This proposed AD would retain the actions
required by AD 2020-12-08 and would require, for certain airplanes,
cleaning and weighing certain mass-balances and installation or
replacement, as applicable; and for certain other mass-balances for
certain airplanes, replacement of those mass-balances. 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 October 25,
2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Background
The FAA issued AD 2020-12-08, Amendment 39-21143 (85 FR 36312, June
16, 2020) (AD 2020-12-08), for Embraer S.A. (type certificate
previously held by Empresa Brasileira de Aeron[aacute]utica S.A.) Model
EMB-505 airplanes, all serial numbers. AD 2020-12-08 was prompted by
reports of corrosion in the mass-balance weights of the flight control
surfaces and a determination that new airworthiness limitations are
necessary. AD 2020-12-08 was based on mandatory continuing
airworthiness information (MCAI) issued by the Ag[ecirc]ncia Nacional
de Avia[ccedil][atilde]o Civil (ANAC), which is the aviation authority
for Brazil. ANAC issued Brazilian Emergency AD No. 2020-01-01, dated
January 9, 2020, to address the unsafe condition on all Embraer S.A.
Model EMB-505 airplanes.
AD 2020-12-08 requires, for certain serial-numbered airplanes,
inspecting the mass-balance weights of the flight control surfaces and
their attachment parts for corrosion and fragmentation, and corrective
actions if necessary, including sending inspection results to Embraer.
For all airplanes, AD 2020-12-08 requires revising the airworthiness
limitation section of the maintenance manual or instructions for
continued airworthiness to incorporate new airworthiness limitations.
The FAA issued AD 2020-12-08 to address corrosion in the mass-
balance weights of the flight control surfaces. The unsafe condition,
if not addressed, could result in loss of mass or the detachment of the
mass-balance weights, resulting in an unbalanced control surface, which
could lead to flutter and loss of airplane control.
Actions Since AD 2020-12-08 Was Issued
Since the FAA issued AD 2020-12-08, ANAC superseded Brazilian
Emergency AD No. 2020-01-01, dated January 9, 2020, and issued
Brazilian AD No. 2020-09-01, dated September 8, 2020 (referred to after
this as ``the MCAI''). The MCAI states:
It has been found the occurrence of corrosion in the mass-
balance weights of the control surfaces. The corrosion may lead to
loss of mass or detachment of the mass-balance weights, resulting in
an unbalance control surface, which, in conjunction with certain
flight conditions, could lead to flutter and possible loss of
airplane control.
Since this condition may occur in other airplanes of the same
type and affects flight safety, a corrective action is required.
Thus, sufficient reason exists to request compliance with this
[ANAC] AD in the indicated time limit.
After [ANAC] EAD 2020-01-01 was released, a reassessment of the
unsafe condition by Embraer and, subsequently, the SB 505-55-0004,
revisions 0 and 1, dated March 25th, 2020 and June 24, 2020,
respectively, expanding the list of affected aircraft serial numbers
(S/Ns) as well as inserting more restrictive criteria to determine
the replacement of affected P/Ns.
Therefore, this [ANAC] AD retains the requirements of [ANAC] EAD
2020-01-01, which is superseded, and incorporates new applicable
aircraft S/Ns and new criteria for the replacement of affected P/Ns.
You may examine the MCAI at https://www.regulations.gov by
searching for and locating Docket No. FAA-2020-1073.
Comments on AD 2020-12-08
The FAA issued AD 2020-12-08 as a final rule; request for comments.
The FAA received comments on AD 2020-12-08 from Flexjet LLC (Flexjet),
an individual, and two anonymous commenters.
Flexjet and an anonymous commenter requested that AD 2020-12-08
allow credit for previous actions using
[[Page 50489]]
Embraer Alert Service Bulletin SB505-55-A004, Revision 5, dated
December 12, 2019 (SB505-550A004 R5), as that service bulletin is not
listed in paragraph (l) of AD 2020-12-08 (``Credit for Previous
Actions'' paragraph).
The FAA notes that the actions of AD 2020-12-08 must be done in
accordance with SB505-55A004 R5. Paragraph (f) of AD 2020-12-08
requires compliance ``unless already done.'' Thus, AD 2020-12-08
already allows operators to take credit for using SB505-55A004 R5 if
done before the effective date of the AD.
Flexjet and an anonymous commenter requested AD 2020-12-08 include
Embraer Service Bulletin SB505-55-0004, dated March 24, 2020 (SB505-55-
0004), as this service bulletin addresses the worldwide fleet.
The FAA agrees. SB505-55-0004 includes additional actions, which
are required by ANAC AD No. 2020-09-01, dated September 8, 2020. This
proposed AD would include those additional requirements.
The individual commenter noted that SB505-55-0004, SB505-55A004 R5,
and Embraer Alert Service Bulletin SB505-55-A004, Revision 06, dated
March 25, 2020, apply to different ranges of serial numbers and
requested the FAA clarify the correct serial numbers for AD 2020-12-08.
AD 2020-12-08 applies to all Model EMB-505 airplanes, regardless of
serial number. However, only those airplanes with a serial number in
SB505-55A004 R5 are required to do the actions in paragraphs (h) and
(k) of AD 2020-12-08.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Embraer Alert Service Bulletin SB505-55-A004,
Revision 06, dated March 25, 2020. This service information specifies
procedures for inspecting the mass-balance weights of the flight
control surfaces and their respective attachment parts for corrosion
and fragmentation, and performing corrective actions on certain serial-
numbered Model EMB-505 airplanes. Corrective actions include
installation of a stainless steel mass-balance, replacement of the
mass-balance, and replacement of attachment parts.
The FAA also reviewed Embraer Service Bulletin SB505-55-0004,
Revision 01, dated June 24, 2020. This service information specifies
procedures, for certain airplanes, for cleaning and weighing the
elevator, aileron, and rudder mass-balances, and installing or
replacing the mass-balances (includes replacing attachment parts), as
applicable, and for certain elevator mass-balances for certain
airplanes, replacing those elevator mass-balances (includes replacing
attachment parts).
Embraer has also issued Alert Service Bulletin SB505-55-A004,
Revision 5, dated December 12, 2019, which the Director of the Federal
Register approved for incorporation by reference as of July 1, 2020 (85
FR 36312, June 16, 2020).
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.
Other Related Service Information
Embraer has issued Embraer Service Bulletin SB505-55-0004, dated
March 25, 2020. The actions specified in Embraer Service Bulletin
SB505-55-0004, dated March 25, 2020, are the same as those specified in
Embraer Alert Service Bulletin SB505-55-0004, Revision 01, dated June
24, 2020; however, Embraer Alert Service Bulletin SB505 55-0004,
Revision 01, dated June 24, 2020, was issued to add serial-numbered
airplanes to the effectivity. No additional work is required for
airplanes on which Embraer Service Bulletin SB505-55-0004, dated March
25, 2020, has been accomplished.
FAA's Determination
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information described above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would retain the actions required by AD 2020-12-08
and would require, for certain airplanes, cleaning and weighing the
elevator, aileron, and rudder mass-balances, and installation or
replacement, as applicable of the mass-balances. This proposed AD would
also remove the reporting required by AD 2020-12-08.
For the retained requirement to revise the airworthiness
limitations section (ALS) of the existing maintenance manual or
instructions for continued airworthiness in paragraph (i) of this
proposed AD, the FAA notes the inspection tasks are part of Chapter 5
of the aircraft maintenance manual--Part III--scheduled maintenance
requirements. This proposed AD would require these tasks as new
airworthiness limitations.
Differences Between This Proposed AD and the Service Information
Embraer Alert Service Bulletin SB505-55-A004, Revision 5, dated
December 12, 2019; and Revision 06, dated March 25, 2020, contain
procedures for inspecting for the integrity of the mass-balance weights
of flight control surfaces and their attachment parts. This proposed AD
would not include that requirement.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 392 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Retained inspections from AD 9 work-hours x $85 $100.............. $865.............. $339,080.
2020[dash]12[dash]08. per hour = $765.
Retained ALS revision from AD 1 work hour x 85 $0................ $85............... $33,320.
2020-12-08. per hour = $85.
New cleaning, weighing, and Up to 130 work- Up to $18,118..... Up to $29,168..... Up to $11,433,856.
replacement. hours x $85 per
hour = Up to
$11,050.
----------------------------------------------------------------------------------------------------------------
[[Page 50490]]
The FAA estimates the following costs to do any necessary
installations or replacements that would be required based on the
results of the inspections and weighing. The FAA has no way of
determining the number of aircraft that might need these actions:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Installation or replacement................... Up to 129 work-hours x $85 per Up to $18,118 Up to $29,083
hour = Up to $10,965.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in this cost estimate.
According to the manufacturer, however, some of the costs of this
proposed 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
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 that the 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
