S.A.; Embraer S.A.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

[[Page 33624]]


ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Embraer S.A. (Type Certificate previously held by Yabor[atilde] 
Ind[uacute]stria Aeron[aacute]utica S.A.; Embraer S.A.) Model ERJ 170-
200 STD, ERJ 170-200 LR, ERJ 170-200 SU, and ERJ 170-200 LL airplanes. 
This AD was prompted by a report of an in-flight detachment of a right-
hand wing tip and the subsequent determination that cracks could 
develop on the wing tip connection area that can affect its structural 
integrity to the point of an in-flight detachment. This AD requires a 
detailed inspection for cracks of the affected wing tip connections, 
corrective action if necessary, and revision of the existing 
maintenance or inspection program, as specified in an Ag[ecirc]ncia 
Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is 
incorporated by reference. The FAA previously sent an emergency AD to 
all known U.S. owners and operators of these airplanes. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective on June 21, 2022. Emergency AD 2022-11-51, 
issued on May 13, 2022, which contained the requirements of this 
amendment, was effective with actual notice.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 21, 
2022.
    The FAA must receive comments on this AD by July 18, 2022.

Background

    The FAA issued Emergency AD 2022-11-51, dated May 13, 2022 (the 
emergency AD), to address an unsafe condition on Embraer S.A. Model ERJ 
170-200 STD, ERJ 170-200 LR, ERJ 170-200 SU, and ERJ 170-200 LL 
airplanes. The FAA sent the emergency AD to all known U.S. owners and 
operators of these airplanes. The emergency AD requires a detailed 
inspection for cracks of the affected wing tip connections, corrective 
action if cracks are found, and revision of the existing maintenance or 
inspection program to include a revised threshold and interval for a 
certain airworthiness limitations task.
    The emergency AD was prompted by Emergency AD 2022-05-02, effective 
May 13, 2022 (ANAC Emergency AD 2022-05-02) (also referred to after 
this as the Mandatory Continuing Airworthiness Information, or the 
MCAI), issued by ANAC, which is the aviation authority for Brazil, to 
correct the unsafe condition for certain Embraer S.A. Model ERJ 170-200 
STD, ERJ 170-200 LR, ERJ 170-200 SU, and ERJ 170-200 LL airplanes. ANAC 
Emergency AD 2022-05-02 was prompted by a report of an in-flight 
detachment of a right-hand wing tip. Subsequently it was determined 
that cracks could develop on the wing tip connection area that can 
affect its structural integrity to the point of an in-flight 
detachment. This condition, if not addressed, even if sufficient 
controllability of the airplane is maintained for the safe continuation 
of the flight, could result in the

[[Page 33625]]

detached part damaging other airplane parts and affecting 
controllability, as well as damaging property and injuring persons on 
the ground.
    See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    ANAC Emergency AD 2022-05-02 specifies procedures for a detailed 
inspection for cracks of the affected wing tip connections, corrective 
action including rework of the wing spar 1 or repair/modification of 
the wingtip spar 1, and revision of the existing maintenance or 
inspection program to include a revised threshold and interval for a 
certain airworthiness limitations task. 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.

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 
described above. The FAA is issuing this AD after determining that the 
unsafe condition described previously is likely to exist or develop on 
other products of the same type design.

AD Requirements

    This AD requires accomplishing the actions specified in ANAC 
Emergency AD 2022-05-02 described previously, except for any 
differences identified as exceptions in the regulatory text of this AD 
and except as discussed under ``Difference Between this AD and the 
MCAI.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
ANAC Emergency AD 2022-05-02 is incorporated by reference in this AD. 
This AD requires compliance with ANAC Emergency AD 2022-05-02 in its 
entirety through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Using 
common terms that are the same as the heading of a particular section 
in ANAC Emergency AD 2022-05-02 does not mean that operators need 
comply only with that section. For example, where the AD refers to 
required actions and compliance, compliance with these AD requirements 
is not limited to the section titled ``Required Action'' or 
``Compliance'' in ANAC Emergency AD 2022-05-02. Service information 
required by ANAC Emergency AD 2022-05-02 for compliance will be 
available at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2022-0597 after this AD is published.

Difference Between This AD and the MCAI

    This AD requires all operators to revise the existing maintenance 
or inspection program, as applicable, to include a reduced threshold 
and interval for a certain airworthiness limitations task. The MCAI 
does not require this action for airplanes with less than 7,500 flight 
hours after installation of an affected part number.

Interim Action

    The FAA considers this AD interim action. The inspection reports 
that are required by this AD will enable the manufacturer to obtain 
better insight into the nature, cause, and extent of the cracking, and 
eventually to develop final action to address the unsafe condition. 
Once final action has been identified, the FAA might consider further 
rulemaking.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that required the immediate adoption of 
Emergency AD 2022-11-51 issued on May 13, 2022, to all known U.S. 
owners and operators of these airplanes. The FAA found that the risk to 
the flying public justified waiving notice and comment prior to 
adoption of this rule because cracks on the wing tip connection area 
can affect its structural integrity to the point of an in-flight 
detachment. Even if sufficient controllability of the airplane is 
maintained for the safe continuation of the flight, this condition 
could result in the detached part damaging other airplane parts and 
affecting controllability, as well as damaging property and injuring 
persons on the ground. These conditions still exist, and the AD is 
hereby published in the Federal Register as an amendment to 14 CFR 
39.13 to make it effective to all persons. Given the significance of 
the risk presented by this unsafe condition, it must be immediately 
addressed. Accordingly, notice and opportunity for prior public comment 
are impracticable and contrary to the public interest pursuant to 5 
U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists 
pursuant to 5 U.S.C. 553(d) for making this amendment effective in less 
than 30 days, for the same reasons the FAA found good cause to forgo 
notice and comment.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 115 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
              Action                        Labor cost            Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Inspections.......................  6 work-hours x $85 per                 $0             $510          $58,650
                                     hour = $510.
----------------------------------------------------------------------------------------------------------------


[[Page 33626]]

    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
FAA 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. Therefore, the 
FAA estimates the total cost per operator to be $7,650 (90 work-hours x 
$85 per work-hour).
    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of the 
inspections. The FAA has no way of determining the number of aircraft 
that might need these actions:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to 
Information Collection Clearance Officer, Federal Aviation 
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

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, and
    (2) Will not affect intrastate aviation in Alaska.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2022-11-51 Embraer S.A. (Type Certificate Previously Held by 
Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A.; Embraer 
S.A.): Amendment 39-22074; Docket No. FAA-2022-0597; Project 
Identifier MCAI-2022-00638-T.

(a) Effective Date

    The FAA issued Emergency Airworthiness Directive (AD) 2022-11-51 
on May 13, 2022, directly to affected owners and operators. As a 
result of such actual notice, the emergency AD was effective for 
those owners and operators on the date it was provided. This AD 
contains the same requirements as that emergency AD and, for those 
who did not receive actual notice, is effective on June 21, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Embraer S.A. (Type Certificate previously 
held by Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A.; 
Embraer S.A.) Model ERJ 170-200 STD, ERJ 170-200 LR, ERJ 170-200 SU, 
and ERJ 170-200 LL airplanes, certificated in any category, as 
identified in Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil 
(ANAC) Emergency AD 2022-05-02, effective May 13, 2022 (ANAC 
Emergency AD 2022-05-02).

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wing 
structure.

(e) Unsafe Condition

    This AD was prompted by a report of an in-flight detachment of a 
right-hand wing tip. Subsequently it was determined that cracks 
could develop on the wing tip connection area that can affect its 
structural integrity to the point of an in-flight detachment. The 
FAA is issuing this AD to address this condition, which, even if 
sufficient controllability of the airplane is maintained for the 
safe continuation of the flight, could result in the detached part 
damaging other airplane parts and affecting controllability, as well 
as damaging property and injuring persons on the ground.

(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, ANAC Emergency AD 2022-05-02.

[[Page 33627]]

(h) Exceptions to ANAC Emergency AD 2022-05-02
