RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 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 Yaborã Indústria Aeronáutica 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 Agência Nacional de Aviação 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 
                    ( print 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

$510
$58,650
 
 
 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 × $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

 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.

 Adoption of 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
 1.The authority citation for part 39 continues to read as follows: Authority:
                        49 U.S.C. 106(g), 40113, 44701. § 39.13
 2.The FAA amends § 39.13 by adding the following new airworthiness directive: **2022-11-51 Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica 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 Yaborã Indústria Aeronáutica 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 Agência Nacional de Aviação 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.
