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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-12-08 
for all Embraer S.A. Model EMB-505 airplanes. AD 2020-12-08 required 
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 (ALS) of the maintenance manual or instructions for 
continued airworthiness to incorporate new airworthiness limitations. 
This AD retains the actions required by AD 2020-12-08 and requires, 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. 
This AD was prompted by a determination that new applicable airplane 
serial numbers and new criteria for the replacement of affected parts 
are necessary. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective April 13, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 13, 
2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of July 
1, 2020 (85 FR 36312, June 16, 2020).

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-12-08, Amendment 39-21143 (85 FR 
36312, June 16, 2020), (AD 2020-12-08). AD 2020-12-08 applied to all 
Embraer S.A. (type certificate previously held by Empresa Brasileira de 
Aeron[aacute]utica S.A.) Model EMB-505 airplanes and required for 
certain serial-numbered airplanes, inspecting the mass-balance weights 
of the flight control surfaces and their attachment parts for corrosion 
and fragmentation, and taking corrective actions if necessary, 
including sending inspection results to Embraer. For all airplanes, AD 
2020-12-08 required revising the airworthiness limitation section of 
the maintenance manual or instructions for continued airworthiness to 
incorporate new airworthiness limitations.
    The NPRM published in the Federal Register on September 9, 2021 (86 
FR 50487). The NPRM was prompted by Brazilian AD 2020-09-01, dated 
September 8, 2020 (referred to after this as ``the MCAI''), issued by 
the Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which 
is the aviation authority for Brazil. The MCAI states:

[[Page 13130]]

    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 [Emergency AD] 2020-01-01 was released, a 
reassessment of the unsafe condition by Embraer and, subsequently, 
the SB [service bulletin] 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 
[part numbers].
    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 in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
1073.
    In the NPRM, the FAA proposed to retain the actions required by AD 
2020-12-08 and proposed to 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. In the NPRM, the FAA also proposed 
to remove the reporting required by AD 2020-12-08.

Ex Parte Contact

    After the comment period closed, the FAA requested clarification 
from Embraer about airplane delivery documentation based on a comment 
from NetJets. A summary of this discussion can be found in the 
rulemaking docket at https://www.regulations.gov in Docket No. FAA-
2020-1073.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from Embraer and NetJets. The following 
presents the comments received on the NPRM and the FAA's response to 
each comment.

Request To Add ``Required for Compliance'' Language

    Embraer requested that the FAA revise the proposed AD to add 
language concerning steps in the service information that are 
``Required for Compliance'' (RC). Specifically, the commenter requested 
the FAA add RC language that has been used in previous ADs for Embraer 
products, which states that steps labeled as RC must be done to comply 
with the AD, while steps not labeled as RC may be deviated from using 
accepted methods. The commenter noted that since the proposed AD 
specifies complying with several steps with an Embraer service 
bulletin, the RC method would be useful in avoiding the need for 
alternative methods of compliance (AMOCs).
    The FAA adds the RC language requested by Embraer to ADs when the 
service information that is incorporated by reference in an AD contains 
steps with the ``RC'' notation. Because none of the steps in the 
service information incorporated by reference in this AD contain the 
``RC'' notation, the language requested by the commenter is 
inapplicable. Additional information about the RC method can be found 
in FAA Advisory Circular (AC) No. 20-176A, Service Bulletins Related to 
Airworthiness Directives and Indicating FAA Approval on Service 
Documents, dated June 16, 2014.\1\
---------------------------------------------------------------------------

    \1\ You can obtain a copy of this AC from the FAA's website at 
https://www.faa.gov/regulations_policies/advisory_circulars/.
---------------------------------------------------------------------------

Request To Add Credit Service Information

    In the NPRM, the FAA proposed to retain the actions in paragraph 
(h) of the AD, which required compliance with Embraer Alert Service 
Bulletin SB505-55-A004, Revision 5, dated December 12, 2019 (SB505-55-
A004R5). The FAA further proposed to allow credit for the actions in 
paragraph (h) of the AD if done previously using Embraer Alert Service 
Bulletin SB505-55-A004, Revision 06, dated March 25, 2020 (SB505-55-
A004R06). For the new actions in paragraphs (l) through (n) of the 
proposed AD, the FAA proposed to require compliance with Embraer 
Service Bulletin SB505-55-0004, Revision 01, dated June 24, 2020 
(SB505-55-0004R01). The FAA further proposed to allow credit for those 
actions if previously done using Embraer Service Bulletin SB505-55-
0004, dated March 25, 2020.
    NetJets requested that the FAA revise the proposed credit 
paragraphs to allow credit for actions required by paragraph (h) of the 
proposed AD if previously done using Embraer SB505-55-A004R5 and credit 
for actions required by paragraphs (l) through (n) of the proposed AD 
if previously done Embraer SB505-55-0004R01.
    The FAA notes that paragraph (f) of this AD requires compliance 
unless already done. Thus, the AD already allows operators to take 
credit for the actions required by paragraphs (h), (l), (m), and (n) if 
done before the effective date of the AD. The commenter's requested 
changes are unnecessary.

Request To Revise Compliance Time

    In the NPRM, the FAA retained certain actions and proposed new 
actions, with compliance times based on the age of the airplane. For 
the retained actions, the FAA proposed that the compliance time remain 
based on ``the date of issuance of the original airworthiness 
certificate or the original export certificate of airworthiness.'' For 
the new actions, the FAA proposed compliance times since new, with a 
proposed definition of ``since new'' as ``since the date of issuance of 
the original airworthiness certificate or the original export 
certificate of airworthiness.''
    NetJets requested the FAA change the proposed compliance time from 
``within 60 months since new'' to ``within the next 60 months scheduled 
maintenance package.'' The commenter stated that, upon aircraft 
delivery, Embraer provides a recommended date to start counting 
calendar inspections and that this recommended start date does not 
always match the date of issuance of the original airworthiness 
certificate or the original export certificate of airworthiness. 
NetJets stated it operates a large fleet of affected aircraft, and if 
the compliance dates in the AD do not align with the scheduled 
maintenance package based on Embraer's recommended state date, it could 
create an undue hardship, potential downtime, and lost revenue. With 
its comment, NetJets provided an example of an Embraer Technical 
Disposition (ETD) letter with a recommended start date for counting 
calendar inspections.
    The FAA has determined that the compliance times, as proposed, 
correspond to the compliance times in the MCAI and will ensure an 
acceptable level of safety. The FAA notes that the change requested by 
the commenter would only affect some inspections required by the AD 
(those that require compliance within 60 months where the term ``since 
new'' is used). Accordingly, the change requested by the commenter 
would result in the compliance times for some of the new inspections 
not aligning with the compliance times for the other new inspections or 
with the retained actions. The FAA has not changed this AD in this 
regard. However, operators may propose a change in the compliance time 
in

[[Page 13131]]

accordance with the AMOC procedures specified in paragraph (p) of this 
AD.

Conclusion

    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 reviewed the relevant 
data and determined that air safety and the public interest require 
adopting this AD as proposed. Accordingly, the FAA is issuing this AD 
to address the unsafe condition on these products. This AD is adopted 
as proposed in the NPRM.

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 the ADDRESSES section.

Other Related Service Information

    Embraer has also 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 SB505-55-0004R01; however, Embraer SB505-55-0004R01 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.

Differences Between This AD and the Service Information

    Embraer SB505-55-A004R5 and Embraer SB505-55-A004R06 contain 
procedures for inspecting for the integrity of the mass-balance weights 
of flight control surfaces and their attachment parts. This AD does not 
include that requirement.

Costs of Compliance

    The FAA estimates that this AD affects 392 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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

    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:

[[Page 13132]]

    (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 Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by:
0
a. Removing Airworthiness Directive 2020-12-08, Amendment 39-21143 (85 
FR 36312, June 16, 2020); and
0
b. Adding the following new airworthiness directive:

2022-05-12 Embraer S.A. (Type Certificate previously held by Empresa 
Brasileira de Aeron[aacute]utica S.A.): Amendment 39-21964; Docket 
No. FAA-2020-1073; Project Identifier MCAI-2020-01303-A.

(a) Effective Date

    This airworthiness directive (AD) is effective April 13, 2022.

(b) Affected ADs

    This AD replaces AD 2020-12-08, Amendment 39-21143 (85 FR 36312, 
June 16, 2020) (AD 2020-12-08).

(c) Applicability

    This AD applies to Embraer S.A. (type certificate previously

airplanes, all serial numbers, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 5520, Elevator 
Structure; 5540, Rudder Structure; and 5751, Ailerons.

(e) Unsafe Condition

    This AD 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. The FAA is issuing this AD 
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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Compliance Times for the Actions Required by Paragraph (h) 
of This AD, With No Changes
