Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
This AD applies to Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) Brazilian AD 2019-06-01, effective June 17, 2019 (“Brazilian AD 2019-06-01”).
The FAA is adopting a new airworthiness directive (AD) for certain Yabor[atilde] Ind[uacute]stria Aeron[aacute]utica S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of structural cracks in the wing lower skin stringers on both half wings. This AD requires repetitive inspections for cracking and fuel leakage of the lower skin stringers on both half wings, and applicable related investigative and corrective actions, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil National Civil Aviation Agency (ANAC) Brazilian AD, which is incorporated by reference. This AD also provides optional terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Brazilian AD 2019-06-01.
Accomplishing the installation of doublers reinforcement on the wing forward and rear lower skin panel, in accordance with the Accomplishment Instructions of Embraer Service Bulletin SB190-57-0056, dated December 5, 2019, terminates the repetitive inspections required by this AD, as specified in Brazilian AD 2019-06-01.
For purposes of determining compliance with the requirements of this AD:
(1) Where Brazilian AD 2019-06-01 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Alternative method of compliance (AMOC)” section of Brazilian AD 2019-06-01 does not apply to this AD.
(3) Where paragraph (a)(1) of Brazilian AD 2019-06-01 specifies an initial inspection time, this AD requires an initial inspection at the applicable time specified in paragraph (i)(3)(i) or (ii) of this AD, whichever occurs later.
(i) Before the accumulation of 17,000 total flight cycles or 27,000 total flight hours, whichever occurs first.
(ii) Within 680 flight cycles or 900 flight hours after the effective date of this AD, whichever occurs first.
(4) Where paragraph (a)(1)(ii) of Brazilian AD 2019-06-01 specifies to do a special detailed inspection (SDI) in case of any “signal” of cracks, this AD requires doing an SDI before further flight after the detection of any “sign” of structural cracks in the inspected area.
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.
