Airworthiness Directive · Amendment 39-22074 · Wing structure
Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
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).
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.
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.
(1) Where ANAC Emergency AD 2022-05-02 refers to its effective date, this AD requires using the effective date of this AD.
(2) For the first column heading of table 1—“Compliance Times” of ANAC Emergency AD 2022-05-02, replace “Flight Hours (FH) accumulated from installation of affected PN” with “Flight Hours (FH) accumulated from installation of affected PN as of the effective date of this (FAA) AD.”
(3) Where table 1—“Compliance Times” of ANAC Emergency AD 2022-05-02 specifies flight hours of “19.800 or greater,” for this AD use flight hours of “19.800 or greater.”
(4) Where paragraphs (a)(i) and (a)(ii) of ANAC Emergency AD 2022-05-02 specify correcting “discrepancies,” this AD defines a discrepancy as a crack.
(5) The inspections and corrective actions specified in paragraphs (a)(i) and (a)(ii) of ANAC Emergency AD 2022-05-02 must be done using the service information specified in paragraphs (a)(i) and (a)(ii) of ANAC Emergency AD 2022-05-02.
(6) Where paragraph (a)(iii) of ANAC Emergency AD 2022-05-02 specifies to “Modify task 57-30-002-0002 of the Airworthiness Limitations Section, on MRB 1621, APPENDIX A—PART 2—AIRWORTHINESS LIMITATION INSPECTIONS (ALI)—STRUCTURES, to revise its compliance interval” at the times in table 1—“Compliance Times” of ANAC Emergency AD 2022-05-02, this AD requires revising the existing maintenance or inspection program, as applicable, within 30 days after the effective date of this AD to incorporate the information specified in table 2—“Airworthiness Limitations Section Updates” of ANAC Emergency AD 2022-05-02; except do not include the information in the “Current Threshold/Interval” column. The initial compliance time for the airworthiness limitations task is within 1,000 flight hours after accomplishment of the tasks specified in paragraphs (a)(i) and (a)(ii) of ANAC Emergency AD 2022-05-02; except, for airplanes that have accumulated 7,499 flight hours or less from installation of an affected part number, as defined in ANAC Emergency AD 2022-05-02, the initial compliance time is before the accumulation of 10,000 flight hours from installation of the affected part number.
(7) Paragraph (b) of ANAC Emergency AD 2022-05-02 specifies to report crack findings to Embraer and ANAC within a certain compliance time. For this AD, report crack findings at the applicable time specified in paragraph (h)(7)(i) or (ii) of this AD.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 36 hours after accomplishment of the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 36 hours after the effective date of this AD.
(8) The “Alternative method of compliance (AMOC)” section of ANAC Emergency AD 2022-05-02 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
